Product details
Overview
SMBJ58C-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 93.6 V maximum clamping voltage (VC) at 6.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ58C-E3/5B datasheet, SMBJ58C-E3/5B pinout, SMBJ58C-E3/5B application, or SMBJ58C-E3/5B equivalent, key selection criteria include unidirectional polarity, 5.0 W steady-state power dissipation, -55 °C to +150 °C operating junction temperature, 100 A IFSM surge rating, and RoHS-compliant matte tin-plated leads suitable for automated SMT placement.
Technical Context
This TVS diode operates as a voltage-clamping protection device in parallel with sensitive circuit nodes. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle. The device is rated for 600 W peak pulse power and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads.
Designed for unidirectional operation, SMBJ58C-E3/5B uses cathode-band marking for polarity identification and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is not AEC-Q101 qualified (suffix lacks HE3/HM3), and its 58 V VWM makes it suitable for 48 V nominal DC bus protection where transient overshoot must be limited below 94 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse working voltage before significant leakage; sets upper limit for normal DC bias operation. |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - Confirmed breakdown range ensures reliable turn-on during overvoltage events without premature conduction. |
| VC @ IPPM | 93.6 V at 6.4 A - Clamping voltage under 10/1000 µs surge defines worst-case stress on downstream components. |
| PPPM | 600 W - Peak pulse power handling capacity determines survivability against lightning-induced or inductive-switching transients. |
| IFSM | 100 A - Single half-sine surge rating (8.3 ms) supports robustness against high-energy AC line faults or motor commutation spikes. |
| TJ max | +150 °C - Maximum junction temperature enables use in high-ambient environments like enclosed industrial enclosures or automotive under-hood zones. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint, compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional configuration with cathode band marking. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path when cathode is at higher transient voltage. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 48 V rail); band-marked end conducts during overvoltage to shunt current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables suppression of high-energy transients common in industrial motor drives and power supply inputs without thermal runaway. |
| Glass passivated chip junction | Ensures long-term reliability and stable VBR performance across temperature and humidity variations in harsh environments. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD or relay bounce), improving protection margin for 3.3 V/5 V logic. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead in high-volume SMT lines. |
| RoHS-compliant, commercial grade (E3 suffix) | Meets global environmental compliance requirements while maintaining cost-effective commercial qualification (not automotive AEC-Q101). |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) Input Protection |
|---|---|
|
Use Scenario: Protects 48 V DC input stage of programmable logic controllers (PLCs) against load dump and inductive switching surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input terminals to clamp transients before they reach upstream DC-DC converters and microcontrollers. Use Value: Limits voltage excursion to ≤93.6 V during 6.4 A surges, preventing damage to 100 V-rated input capacitors and enabling use of lower-voltage-rated downstream components. |
Use Scenario: Shields LIN bus interface and power inputs of BCM modules from battery line transients during jump-start or alternator load dump. IC Role / Device Role / Timing Role: Standoff-rated TVS on 12 V/24 V supply rails absorbs energy from ISO 7637-2 Pulse 5a (load dump) events. Use Value: With 58 V VWM, it remains non-conductive during normal operation but clamps within spec during 120 V/500 ms load dump pulses, preserving system uptime. |
| Telecom Remote Radio Unit (RRU) Power Interface | Consumer Smart Home Gateway DC Input Protection |
|
Use Scenario: Guards PoE-powered remote radio units against induced surges from nearby lightning strikes on outdoor cabling. IC Role / Device Role / Timing Role: Primary front-end TVS on 48 V PoE input, coordinated with secondary GDT or MOV for staged protection. Use Value: 600 W rating handles multi-kA induced surges; fast response (<1 ns) prevents latch-up in RF front-end amplifiers before slower protection stages activate. |
Use Scenario: Secures 12 V DC adapter input of smart home gateways against ESD and AC adapter plug-in transients. IC Role / Device Role / Timing Role: First-line unidirectional suppressor on main DC input, placed before fuse and input filter capacitor. Use Value: 93.6 V clamping voltage ensures downstream 16 V-rated electrolytic capacitors and LDO regulators remain within safe operating limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-E3/5B | Same VWM (58 V), identical package and ratings; differs only in marking code (A vs C) - both denote unidirectional SMBJ58x family members per Vishay documentation. | No functional difference; SMBJ58A-E3/5B is the base designation; SMBJ58C-E3/5B is an alternate marking variant with identical electrical specs. | Select SMBJ58C-E3/5B when matching existing BOMs or legacy design documentation referencing the "C" suffix variant. |
| SMCJ58A-E3/57T | Higher power rating (1500 W), larger SMC (DO-214AB) package, same VWM/VC - requires PCB layout change and higher mounting pad area. | Suitable for higher-energy threat environments (e.g., railway or utility-grade equipment) where 600 W is insufficient. | Choose SMCJ58A-E3/57T only if system-level testing confirms need for >600 W surge handling; otherwise, SMBJ58C-E3/5B offers optimal size-power balance. |
Compared with SMBJ58A-E3/5B (identical function, alternate marking) and SMCJ58A-E3/57T (higher-power, larger package), SMBJ58C-E3/5B delivers verified 600 W transient suppression in the smallest standardized SMB footprint - ideal for space-constrained 48 V industrial and telecom power interfaces where layout revision is not feasible.

FAQ
What is the polarity configuration of SMBJ58C-E3/5B?
SMBJ58C-E3/5B is a unidirectional TVS diode, with the cathode identified by a visible band on the SMB (DO-214AA) package. This configuration allows it to conduct only when the cathode is at a higher potential than the anode - making it suitable for DC line protection where reverse voltage is not expected. Its unidirectional behavior is confirmed in Vishay's SMBJ5.0A–SMBJ188A datasheet, section "Polarity".
Does SMBJ58C-E3/5B meet AEC-Q101 automotive qualification?
No, SMBJ58C-E3/5B does not meet AEC-Q101 qualification. It carries the "E3" suffix, indicating RoHS-compliant commercial grade per Vishay's ordering information table. AEC-Q101 qualified variants use "HE3" or "HM3" suffixes (e.g., SMBJ58AHE3_B/I). For automotive applications requiring qualification, SMBJ58C-E3/5B must be validated separately by the end customer per their internal reliability requirements.
What is the maximum clamping voltage of SMBJ58C-E3/5B under surge conditions?
The maximum clamping voltage (VC) of SMBJ58C-E3/5B is 93.6 V at 6.4 A peak pulse current (IPPM) with a 10/1000 µs waveform, as specified in the Electrical Characteristics table of Vishay document 88392. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is critical for ensuring downstream components remain within their absolute maximum ratings.
Can SMBJ58C-E3/5B be used in bidirectional signal line protection?
No, SMBJ58C-E3/5B is unidirectional and not suitable for bidirectional signal line protection. Bidirectional operation requires the "CA" suffix (e.g., SMBJ58CA), which implements symmetrical breakdown in both directions. Using SMBJ58C-E3/5B on AC or bidirectional data lines risks forward conduction during negative half-cycles and failure to suppress reverse transients - refer to Vishay's note: "For bidirectional devices use CA suffix."
What is the thermal resistance and derating behavior of SMBJ58C-E3/5B?
SMBJ58C-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads, per Vishay's Thermal Characteristics table. Its peak pulse power must be derated linearly above 25 °C ambient, with full 600 W rating only at TA = 25 °C - dropping to ~400 W at 75 °C and ~200 W at 125 °C, as shown in Figure 2 of document 88392.
