Product details
Overview
SMBJ36D-M3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 36 V stand-off voltage (VWM), 40.6–43.6 V breakdown voltage (VBR) at 1 mA, 57.3 V clamping voltage (VC) at 10.5 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in industrial motor drives, telecom power supplies, and automotive body control modules.
For engineers reviewing the SMBJ36D-M3/I datasheet, SMBJ36D-M3/I pinout, SMBJ36D-M3/I application, or SMBJ36D-M3/I equivalent, key selection criteria include unidirectional polarity, ±3.5 % VBR tolerance, M3 halogen-free RoHS-compliant construction, 150 °C max junction temperature, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM (36 V) and rapidly transitions to low-impedance conduction above VBR (min 40.6 V), limiting transient-induced overvoltage to ≤57.3 V at 10.5 A. Its low incremental surge resistance and fast response time ensure effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The SMBJ36D-M3/I is rated for 600 W peak pulse power (10/1000 μs), derated linearly above 25 °C ambient per Fig. 2, with thermal resistance RθJA = 125 °C/W on minimum recommended pad layout. It meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-M3/I | Bidirectional variant; symmetric VBR/VWM (36 V both polarities); same PPPM, VC, and package | Required where AC-coupled or dual-polarity transients (e.g., RS-485, Ethernet PHY) must be suppressed | Select SMBJ36A-M3/I only if bidirectional clamping is needed; SMBJ36D-M3/I is optimal for DC rail protection with defined polarity |
| SMAJ36A-M3/8A | Lower PPPM (400 W), higher VC (63.6 V at 6.3 A), SMA package (smaller footprint, higher RθJA) | Suitable for space-constrained designs with lower surge severity (e.g., IEC 61000-4-2 ESD only) | Choose SMAJ36A-M3/8A when board area is critical and 600 W surge immunity is not required; SMBJ36D-M3/I delivers superior power handling |
Compared with SMBJ36A-M3/I and SMAJ36A-M3/8A, the SMBJ36D-M3/I provides unidirectional clamping optimized for DC power rails, higher 600 W surge capacity than SMAJ variants, and tighter VBR tolerance - making it preferred for industrial and automotive applications demanding precise, high-energy transient suppression.

FAQ
What is the breakdown voltage range for SMBJ36D-M3/I?
The SMBJ36D-M3/I has a specified breakdown voltage (VBR) range of 40.6 V to 43.6 V at 1 mA test current, reflecting a tight ±3.5 % tolerance. This precise VBR window ensures consistent clamping behavior across production units and supports accurate system-level overvoltage margining in designs using the SMBJ36D-M3/I.
Is SMBJ36D-M3/I unidirectional or bidirectional?
SMBJ36D-M3/I is a unidirectional transient voltage suppressor, indicated by the "D" suffix and presence of a cathode band. It conducts only when the cathode is biased positively relative to the anode, making it suitable for DC rail protection where polarity is fixed - unlike bidirectional variants (e.g., SMBJ36CD-M3/I) used for AC or differential signal lines.
What does the "M3" suffix mean in SMBJ36D-M3/I?
The "M3" suffix denotes Vishay's industrial-grade, halogen-free, RoHS-compliant construction with matte tin-plated leads qualified to JESD 201 Class 2 whisker resistance. It also confirms compliance with J-STD-020 MSL Level 1 and UL 94 V-0 flammability - all verified specifications for the SMBJ36D-M3/I.
Can SMBJ36D-M3/I be used in automotive applications?
Yes, SMBJ36D-M3/I is qualified for automotive use with a junction temperature range of –55 °C to +150 °C and robust surge ratings meeting ISO 7637-2 Pulse 5a requirements. Its M3 qualification, low leakage (<0.5 μA), and stable VBR make it suitable for body control modules, infotainment power rails, and sensor interface protection in the SMBJ36D-M3/I design context.
What is the clamping voltage of SMBJ36D-M3/I at its rated peak pulse current?
The SMBJ36D-M3/I clamps to a maximum of 57.3 V at its rated peak pulse current (IPPM) of 10.5 A, measured with a 10/1000 μs waveform. This VC value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is a critical parameter for validating safe operation of downstream ICs when using the SMBJ36D-M3/I.
