Product details
Overview
SMBJ90D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 90 V stand-off voltage (VWM), 102–109 V breakdown voltage (VBR) at 1 mA, 144 V maximum clamping voltage (VC) at 4.17 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMBJ90D-M3/H datasheet, SMBJ90D-M3/H pinout, SMBJ90D-M3/H application, or SMBJ90D-M3/H equivalent, key selection criteria include clamping performance under 4.17 A surge, thermal resistance (RθJA = 125 °C/W on minimum pad), unidirectional polarity with cathode band marking, and industrial-grade halogen-free M3 construction compliant with JESD 201 class 2 whisker test.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, activating when reverse voltage exceeds its VBR range (102–109 V) to divert transient energy away from downstream circuitry. Its low incremental surge resistance and fast response time ensure effective suppression of 10/1000 μs transients without significant voltage overshoot.
Designed for operation across -55 °C to +150 °C junction temperature range, SMBJ90D-M3/H delivers 1.0 W steady-state power dissipation at 25 °C ambient and 5.0 W at 50 °C case temperature, with derating governed by Fig. 5 in the Vishay datasheet. The device meets UL 497B recognition (QVGQ2) and complies with MSL level 1 per J-STD-020.
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 |
|---|---|---|---|
| SMBJ90A-M3/H | Same package and VWM, but bidirectional; symmetric clamping in both polarities | Required where AC-coupled or dual-polarity signal lines need protection (e.g., RS-485, CAN) | Select SMBJ90A-M3/H only if bidirectional clamping is required; SMBJ90D-M3/H is optimal for DC rail or unidirectional signal protection. |
| SMCJ90A | Larger SMC (DO-214AB) package; higher 1500 W PPPM rating; same 90 V VWM and bidirectional configuration | Used where higher surge energy handling is needed and board space allows larger footprint | Choose SMCJ90A when system-level surge testing exceeds 600 W requirements; SMBJ90D-M3/H fits tighter layouts with adequate 600 W rating for most industrial IEC 61000-4-5 applications. |
Compared with SMBJ90A-M3/H and SMCJ90A, SMBJ90D-M3/H provides optimized unidirectional clamping in the smallest standard surface-mount TVS package with verified 600 W surge capability, making it ideal for space-constrained DC power and signal line protection where polarity is fixed and bidirectional behavior is unnecessary.

FAQ
What is the breakdown voltage range for SMBJ90D-M3/H?
The SMBJ90D-M3/H has a guaranteed breakdown voltage (VBR) range of 102 V to 109 V at 1 mA test current, reflecting a tight ±3.5 % tolerance. This specification is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 09-Jan-2024 (Document Number: 87606). The narrow VBR window ensures consistent clamping behavior across production lots and simplifies system-level overvoltage margining for the SMBJ90D-M3/H.
Does SMBJ90D-M3/H support lead-free reflow soldering?
Yes, SMBJ90D-M3/H is rated for lead-free reflow soldering with a maximum peak temperature of 260 °C and meets MSL level 1 per J-STD-020. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards. The M3 suffix explicitly confirms qualification to JESD 201 class 2 whisker resistance, making SMBJ90D-M3/H suitable for high-reliability automated assembly processes without moisture sensitivity concerns.
What is the maximum clamping voltage of SMBJ90D-M3/H under surge conditions?
The SMBJ90D-M3/H exhibits a maximum clamping voltage (VC) of 144 V when subjected to its rated peak pulse current (IPPM) of 4.17 A using the standard 10/1000 μs waveform. This value is specified in the Electrical Characteristics table of the Vishay datasheet and represents the upper bound of voltage seen by protected circuitry during worst-case transient events. Designers use this VC value to verify that downstream components remain within their absolute maximum ratings during surge conditions involving the SMBJ90D-M3/H.
Is SMBJ90D-M3/H certified for use in safety-critical telecom applications?
Yes, SMBJ90D-M3/H carries Underwriters Laboratory (UL) recognition under file number E136766 for both unidirectional and bidirectional variants, complying with UL 497B for signal circuit protectors. This certification validates its suitability in telecom infrastructure equipment requiring third-party safety approval. The SMBJ90D-M3/H is explicitly listed in the UL QVGQ2 category, confirming its qualification for use in safety-critical telecom line interface designs where certified transient suppression is mandated.
How does the thermal resistance of SMBJ90D-M3/H affect PCB layout?
The SMBJ90D-M3/H has a typical junction-to-ambient thermal resistance (RθJA) of 125 °C/W when mounted on the minimum recommended pad layout per Vishay's datasheet. This value means that for every watt of power dissipated, the junction temperature rises 125 °C above ambient - so even 1 W of sustained dissipation could exceed the 150 °C TJ max if ambient exceeds 25 °C. To maintain reliability, designers must use adequate copper area (e.g., 5.0 mm × 5.0 mm pads) to reduce RθJA toward the 100 °C/W value specified for larger pads, especially in high-temperature environments where SMBJ90D-M3/H operates near its thermal limits.
