Product details
Overview
SMBJ5.0C-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection of sensitive ICs, MOSFETs, and signal lines in consumer, industrial, and telecom systems. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps transients to ≤9.2 V at 65.2 A.
For engineers reviewing the SMBJ5.0C-E3/52 datasheet, SMBJ5.0C-E3/52 pinout, SMBJ5.0C-E3/52 application, or SMBJ5.0C-E3/52 equivalent, key selection criteria include its unidirectional polarity, SMB (DO-214AA) package compatibility with automated placement, low clamping voltage under surge, and RoHS-compliant commercial-grade construction with matte tin-plated leads.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with power or signal paths, conducting only when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<800 µA at VWM), while its 100 °C/W junction-to-ambient thermal resistance supports operation up to +150 °C junction temperature.
The SMBJ5.0C-E3/52 delivers 600 W peak pulse power per 10/1000 µs waveform with 0.01% duty cycle, and exhibits fast response time (<1.0 ps) and low incremental surge resistance - critical for suppressing ESD, lightning-induced surges, and inductive switching transients before downstream components are damaged.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - Confirmed breakdown range ensures reliable triggering across process variation and temperature. |
| VC @ IPPM | ≤9.2 V at 65.2 A - Clamping voltage during 600 W surge; determines maximum stress imposed on protected circuitry. |
| PPPM | 600 W (10/1000 µs) - Peak transient energy absorption capability; validates suitability for IEC 61000-4-5 Level 3/4 surge immunity. |
| IFSM | 100 A (8.3 ms half-sine) - Surge current rating for unidirectional forward conduction; supports inrush and fault-current events. |
| Junction Temp. Range | −55 °C to +150 °C - Enables deployment in automotive under-hood, industrial control, and outdoor telecom environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with IPC-7351B land patterns. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to system ground or low-side return path; defines polarity-dependent clamping direction. |
| Cathode | Reverse voltage input / Surge current sink | Connected to protected line (e.g., VIN, signal trace); conducts surge current to ground when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Validated for IEC 61000-4-5 surge immunity up to 4 kV (line-earth) without derating on standard PCB copper pads. |
| Low clamping voltage (≤9.2 V) | Enables protection of 5 V logic rails and USB/RS-485 transceivers without violating absolute maximum ratings. |
| Glass passivated junction | Ensures stable VBR tolerance (±5%), low leakage (<800 µA), and long-term reliability under repeated surge stress. |
| SMB (DO-214AA) package | Supports high-volume automated pick-and-place assembly; footprint matches industry-standard layout guidelines for thermal dissipation. |
| RoHS-compliant, commercial grade | E3 suffix confirms lead-free, halogen-free compliance per JEDEC J-STD-020 MSL Level 1 (260 °C peak reflow). |
Applications
| USB Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
|
Use Scenario: Protecting 5 V USB VBUS lines against hot-plug transients, ESD, and nearby relay switching noise in embedded host devices. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between VBUS and GND, triggered within picoseconds of overvoltage onset. Use Value: Limits voltage excursion to ≤9.2 V during 65.2 A surge, preventing damage to USB controller ICs rated for 6 V absolute max. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA, 0–10 V) from field-wiring induced surges in PLC I/O modules. IC Role / Device Role / Timing Role: Standoff-connected TVS on signal path, absorbing inductive kickback from solenoid or motor feedback loops. Use Value: Clamps 600 W transients while maintaining <800 µA leakage at 5.0 V, preserving signal integrity and ADC accuracy. |
| DC Power Rail Protection (5 V) | Telecom Line Interface Protection |
|
Use Scenario: Secondary overvoltage defense on regulated 5 V supply rails feeding microcontrollers, memory, and interface ICs. IC Role / Device Role / Timing Role: Parallel-connected transient suppressor referenced to local ground plane; activated only during fault conditions. Use Value: Withstands 100 A 8.3 ms forward surge, enabling coordination with upstream fuses or e-fuses in multi-layer protection schemes. |
Use Scenario: Front-end surge suppression on low-voltage telecom interfaces (e.g., Ethernet PHY bias rails, management bus lines). IC Role / Device Role / Timing Role: Unidirectional clamp on isolated DC bias lines, coordinated with common-mode chokes and isolation transformers. Use Value: Meets GR-1089-CORE Level 3 surge requirements with no additional external components due to low Rsurge and fast response. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Unidirectional variant with identical VWM, VBR, and PPPM; differs only in marking code (KE vs. KE) and absence of "C" suffix - indicating same electrical spec. | No functional difference; both rated for 5.0 V standoff and 600 W surge. SMBJ5.0A-E3/52 is functionally identical but lacks explicit "C" designation in part number. | Select SMBJ5.0C-E3/52 when documentation or BOM requires explicit "C"-suffixed ordering code; otherwise SMBJ5.0A-E3/52 is electrically interchangeable. |
| SMCJ5.0A-E3/52 | Same VWM and VBR, but higher PPPM = 1500 W and larger SMC (DO-214AB) package; 2.5× higher surge current rating (172 A). | Used where higher surge robustness is required (e.g., outdoor PoE injectors, AC/DC front ends); not drop-in due to larger footprint and thermal mass. | Choose SMBJ5.0C-E3/52 for space-constrained 5 V rail protection with standard surge immunity; upgrade to SMCJ5.0A-E3/52 only if 1500 W rating and board area permit. |
Compared with SMBJ5.0A-E3/52, the SMBJ5.0C-E3/52 offers identical electrical performance and packaging, differing only in manufacturer-marked suffix convention; versus SMCJ5.0A-E3/52, it trades surge capacity for compact SMB footprint - making it optimal for dense consumer and telecom PCB layouts requiring certified 600 W protection.

FAQ
What is the breakdown voltage range of the SMBJ5.0C-E3/52?
The SMBJ5.0C-E3/52 has a guaranteed breakdown voltage (VBR) range of 6.4 V to 7.07 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent triggering behavior across temperature and unit-to-unit variation, directly supporting design margin calculations for 5 V systems.
Is the SMBJ5.0C-E3/52 unidirectional or bidirectional?
The SMBJ5.0C-E3/52 is a unidirectional TVS diode, as confirmed by its "C" suffix (per Vishay's naming convention) and cathode band marking. It conducts surge current only in reverse bias - from cathode to anode - and must be oriented with cathode toward the protected line and anode to ground.
What does the "-E3/52" suffix indicate in SMBJ5.0C-E3/52?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/52" specifies packaging in 7″ diameter plastic tape and reel, with 750 units per reel. This configuration meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance requirements.
Can SMBJ5.0C-E3/52 replace SMBJ5.0A-E3/52 in a design?
Yes - SMBJ5.0C-E3/52 and SMBJ5.0A-E3/52 share identical electrical specifications (VWM = 5.0 V, VBR = 6.4–7.07 V, PPPM = 600 W), package (SMB), and thermal characteristics. The "C" and "A" suffixes reflect Vishay's internal marking variants for the same unidirectional device; no layout or performance change is required.
What is the maximum clamping voltage of SMBJ5.0C-E3/52 under surge conditions?
The SMBJ5.0C-E3/52 clamps to a maximum of 9.2 V at its rated peak pulse current of 65.2 A (10/1000 µs waveform). This value is guaranteed per datasheet Table 1 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
