Product details
Overview
SMBJ58D-M3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive switching transients and ESD events on power and signal lines. It features a 58 V stand-off voltage (VWM), 65.4–70.2 V breakdown voltage (VBR) at 1 mA, 92.3 V maximum clamping voltage (VC) at 6.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMBJ58D-M3/I datasheet, SMBJ58D-M3/I pinout, SMBJ58D-M3/I application, or SMBJ58D-M3/I equivalent, key selection criteria include unidirectional polarity, ±3.5 % VBR tolerance, low leakage (<0.5 μA at VWM), M3 halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates as a voltage-clamping protection device placed in parallel with sensitive circuit nodes. Its silicon avalanche structure enables sub-nanosecond response to transients, with clamping action triggered when reverse voltage exceeds VBR, limiting downstream voltage to ≤92.3 V at 6.5 A IPPM.
Thermal performance is defined by RθJA = 125 °C/W (on minimum pad) and RθJM = 20 °C/W, supporting operation from –55 °C to +150 °C junction temperature. Power derating begins above TA = 25 °C, with 1.0 W steady-state dissipation at ambient and 5.0 W at TM = 50 °C on infinite heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 58 V - Maximum continuous reverse operating voltage before significant conduction begins |
| VBR (Breakdown Voltage) | 65.4–70.2 V at 1 mA - Tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC (Clamping Voltage) | 92.3 V at IPPM = 6.5 A - Limits transient voltage seen by protected IC or MOSFET during surge |
| PPPM (Peak Pulse Power) | 600 W with 10/1000 μs waveform - Withstands high-energy surges common in industrial motor drives and telecom interfaces |
| ID (Reverse Leakage) | <0.5 μA at VWM - Minimizes standby power loss and avoids false triggering in low-current sensor circuits |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with IPC-7351B standard, supports automated pick-and-place |
| Polarity | Unidirectional - Cathode band denotes terminal; blocks forward current, clamps reverse transients only |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards; M3 suffix indicates halogen-free, RoHS-compliant, industrial-grade construction with JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / low-impedance return during clamping | Connected to system ground or lower-potential rail; carries full surge current during transient suppression |
| Cathode (banded end) | Reverse-biased clamping node | Connected to protected line (e.g., 48 V supply rail or RS-485 bus); initiates avalanche conduction when V > VBR |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-M3/I | Bidirectional variant; symmetrical VBR (65.4–70.2 V) in both polarities; no cathode band marking | Required where AC-coupled lines (e.g., RS-485, CAN) need clamping for both positive and negative transients | Select SMBJ58A-M3/I only if bidirectional protection is mandated; SMBJ58D-M3/I is preferred for DC rails with defined polarity |
| SMCJ58A-M3/I | Larger SMC (DO-214AB) package; same VWM/VBR/VC specs but higher 1500 W PPPM rating and lower RθJA (60 °C/W) | Suitable for higher-energy surge environments (e.g., outdoor telecom cabinets) where 600 W is insufficient | Choose SMCJ58A-M3/I when surge energy exceeds SMBJ58D-M3/I capability; requires larger PCB footprint and layout revision |
Compared with SMBJ58D-M3/I, SMBJ58A-M3/I provides bidirectional clamping at identical voltage ratings but lacks polarity identification, while SMCJ58A-M3/I delivers 2.5× higher surge power handling in a physically larger package-requiring trade-offs between board space, thermal margin, and protection level.

FAQ
What is the maximum clamping voltage of SMBJ58D-M3/I at its rated peak pulse current?
The SMBJ58D-M3/I has a maximum clamping voltage (VC) of 92.3 V when subjected to its peak pulse current (IPPM) of 6.5 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees the upper voltage limit imposed on protected circuitry during surge events, making SMBJ58D-M3/I suitable for safeguarding 60 V-rated components in industrial power systems.
Is SMBJ58D-M3/I compatible with lead-free reflow soldering processes?
Yes, SMBJ58D-M3/I meets MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, fully compatible with standard lead-free (SnAgCu) soldering profiles. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, ensuring reliable wetting and joint integrity without pre-baking or special handling-critical for high-yield SMT manufacturing of SMBJ58D-M3/I.
How does the VWM of 58 V relate to the breakdown voltage range of SMBJ58D-M3/I?
The 58 V stand-off voltage (VWM) of SMBJ58D-M3/I is the maximum DC or continuous reverse voltage the device can block without entering avalanche conduction; its specified breakdown voltage (VBR) range of 65.4–70.2 V at 1 mA ensures ≥7.4 V margin above VWM. This design margin prevents false triggering during normal operation while guaranteeing activation within 100 ns when transients exceed the lower VBR limit-key for reliable SMBJ58D-M3/I deployment in noisy 48 V systems.
What is the reverse leakage current specification for SMBJ58D-M3/I at its rated VWM?
SMBJ58D-M3/I exhibits a maximum reverse leakage current (ID) of 0.5 μA at its 58 V stand-off voltage (VWM) and TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes quiescent power loss in always-on industrial control circuits-confirming SMBJ58D-M3/I's suitability for precision analog and battery-backed applications where standby current matters.
Does SMBJ58D-M3/I have a defined polarity, and how is it marked on the package?
Yes, SMBJ58D-M3/I is a unidirectional TVS diode with clearly defined polarity: the cathode is identified by a distinct band printed on the SMB (DO-214AA) package body. During PCB layout, the banded end must be connected to the line being protected (e.g., 48 V rail), while the anode connects to ground-ensuring correct orientation for reverse-biased clamping operation and preventing forward conduction during normal system operation of SMBJ58D-M3/I.
