Product details
Overview
SMBJ58CD-M3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 58 V stand-off voltage (VWM), 65.4–70.2 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), and clamps to ≤92.3 V at 6.5 A peak surge current - deployed in industrial sensor interfaces and telecom line protection.
For engineers reviewing the SMBJ58CD-M3/I datasheet, SMBJ58CD-M3/I pinout, SMBJ58CD-M3/I application, or SMBJ58CD-M3/I equivalent, key selection criteria include bidirectional clamping capability, ±3.5% VBR tolerance, low leakage (<0.5 μA at VWM), MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction per JESD 201 Class 2 whisker test.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both polarities, enabling suppression of positive and negative transients without polarity dependency. Its low incremental surge resistance and fast response time ensure effective protection against ESD, lightning-induced surges, and inductive switching spikes.
The SMBJ58CD-M3/I is rated for 150 °C maximum junction temperature, derated linearly above 25 °C ambient, with thermal resistance RθJA = 125 °C/W on minimum pad layout and RθJM = 20 °C/W to mounting surface - critical for sustained surge handling in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR min/max | 65.4 V / 70.2 V at 1 mA - tight ±3.5% tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | ≤92.3 V at 6.5 A - clamping voltage under 600 W 10/1000 μs surge; limits stress on downstream components. |
| ID @ VWM | ≤0.5 μA - ultra-low leakage preserves signal integrity and battery life in always-on interfaces. |
| PPPM | 600 W - peak transient energy absorption capability per single 10/1000 μs pulse at 0.01% duty cycle. |
| TJ max | 150 °C - enables operation in harsh industrial environments with minimal derating. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height. |
Pinout & Package
Two-terminal bidirectional device in SMB (DO-214AA) package; no polarity marking - symmetric terminals accept voltage transients in either direction. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, with M3 suffix confirming halogen-free, RoHS-compliant, industrial-grade construction and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; no cathode band - enables layout flexibility and eliminates polarity orientation errors during placement. |
| Cathode Band (absent) | Polarity indicator | Not present - confirms bidirectional functionality; distinguishes SMBJ58CD-M3/I from unidirectional variants like SMBJ58D-M3/I. |

| ±3.5% VBR tolerance | Reduces design margin requirements and improves consistency in multi-channel protection schemes. |
| 600 W peak pulse rating | Meets IEC 61000-4-5 Level 4 (4 kV surge) when combined with appropriate series impedance. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without pre-baking, simplifying manufacturing flow. |
| Halogen-free & RoHS | Complies with environmental regulations and avoids corrosive decomposition products under fault conditions. |
Applications
| Industrial Sensor Interface | Telecom Line Protection |
|---|---|
Use Scenario: Protecting analog output lines (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors in factory automation cabinets exposed to relay coil flyback and ground bounce. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed directly at connector entry point, shunting transients before reaching precision ADC or op-amp front-end. Use Value: Prevents latch-up or parametric shift in signal conditioning ICs by limiting transient excursions to ≤92.3 V while maintaining <0.5 μA leakage at 58 V nominal. |
Use Scenario: Safeguarding RS-485 transceiver bus lines in outdoor base station backhaul units subjected to induced lightning surges. IC Role / Device Role / Timing Role: Bidirectional transient suppressor mounted differential pair (A/B) with common-mode choke, absorbing common- and differential-mode surges. Use Value: Maintains data integrity during 600 W surges by clamping within 1.5 ns response time and holding VWM at 58 V to avoid false triggering during normal 5 V or 3.3 V logic swings. |
| Power Supply Input Stage | Automotive Body Control Module |
Use Scenario: Secondary overvoltage protection on 48 V DC input rails of PoE-powered edge computing nodes after primary DC-DC converter. IC Role / Device Role / Timing Role: Standoff-rated TVS placed post-filtering but pre-LDO, acting as last-line defense against load dump or hot-swap transients. Use Value: Withstands repetitive 600 W pulses at 0.01% duty cycle and dissipates 1.0 W at 25 °C ambient - sufficient for intermittent surge events without thermal runaway. |
Use Scenario: CAN FD physical layer protection in body control modules where LIN/CAN buses share chassis ground with high-current actuators. IC Role / Device Role / Timing Role: Bidirectional clamp on CAN_H/CAN_L differential pair, coordinated with common-mode choke to meet ISO 16750-2 pulse 5a/b immunity. Use Value: Matches CAN FD's 5 Mbps timing budget with sub-nanosecond response and maintains signal rise/fall times due to low junction capacitance (<100 pF at 0 V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA-M3/5B (Vishay) | Same VWM/VBR/PPPM specs; differs only in packaging - 7" tape (5B) vs. 13" tape (I); identical electrical and thermal performance. | No functional difference; selected based on SMT line reel size compatibility and volume order batching. | Choose SMBJ58CA-M3/5B only if 7" reels align with pick-and-place feeder configuration and lot-size planning. |
| SMCJ58CA (Littelfuse) | Same SMB package and bidirectional 58 V rating, but higher 1500 W PPPM rating and larger 7.11 mm × 6.22 mm SMC (DO-214AB) footprint. | Requires PCB layout change; suited for higher-energy surge environments where 600 W is insufficient. | Select SMCJ58CA only when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space allows larger SMC footprint. |
Compared with SMBJ58CD-M3/I, SMBJ58CA-M3/5B offers identical protection performance in a different reel format, while SMCJ58CA provides higher surge capacity at the cost of larger board area and non-drop-in replacement - making SMBJ58CD-M3/I optimal for space-constrained 600 W-class designs requiring M3-grade reliability.

FAQ
What is the clamping voltage of SMBJ58CD-M3/I at its rated peak pulse current?
The SMBJ58CD-M3/I clamps to a maximum of 92.3 V at its specified peak pulse current of 6.5 A (10/1000 μs waveform). This value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The SMBJ58CD-M3/I achieves this clamping performance while maintaining low incremental surge resistance, ensuring consistent protection across production units.
Is SMBJ58CD-M3/I suitable for bidirectional signal line protection?
Yes, SMBJ58CD-M3/I is explicitly designed for bidirectional applications, as indicated by the "CD" suffix and confirmed by its symmetrical electrical characteristics in both polarities. It has no cathode band and exhibits matched VBR and VC values regardless of voltage polarity - making it ideal for protecting AC-coupled interfaces like RS-485, CAN, or audio lines where signal swing crosses zero. The SMBJ58CD-M3/I delivers identical clamping behavior for positive and negative transients.
What does the "M3" suffix signify in SMBJ58CD-M3/I?
Within the Vishay SMBJ series, the "M3" suffix denotes halogen-free, RoHS-compliant construction meeting JESD 201 Class 2 whisker resistance requirements, and industrial-grade qualification. It also specifies matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. The "M3" designation applies to the SMBJ58CD-M3/I device itself - not just packaging - and is verified per material categorization document 99912. This ensures reliability in high-reliability production environments.
How does SMBJ58CD-M3/I compare to unidirectional SMBJ58D-M3/I in layout and usage?
The SMBJ58CD-M3/I differs from SMBJ58D-M3/I primarily in polarity: SMBJ58CD-M3/I is bidirectional with no cathode band and symmetrical IV characteristics, while SMBJ58D-M3/I is unidirectional with a visible cathode band and conducts only in reverse bias. Layout for SMBJ58CD-M3/I requires no orientation check, simplifying automated placement and reducing assembly errors. Both share identical SMB (DO-214AA) mechanical dimensions and thermal ratings, but SMBJ58CD-M3/I must be used where bipolar transients occur.
What is the maximum steady-state power dissipation of SMBJ58CD-M3/I at room temperature?
The SMBJ58CD-M3/I has a maximum steady-state power dissipation (PD) of 1.0 W at TA = 25 °C when mounted on standard PCB pads, and 5.0 W at TM = 50 °C when mounted on an infinite heatsink. These ratings reflect continuous DC or low-frequency power handling - distinct from its 600 W peak pulse capability. For reliable long-term operation, designers must apply thermal derating curves (Fig. 5 in datasheet 87606) when ambient temperatures exceed 25 °C or when PCB copper area is less than the recommended 5.0 mm × 5.0 mm pad.
