Product details
Overview
SMBJ150D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection of DC power rails and signal lines. It features a 150 V stand-off voltage (VWM), 170–182 V breakdown voltage (VBR) at 1 mA, 239 V clamping voltage (VC) at 2.53 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, I/O interfaces, and industrial sensor front-ends against lightning-induced transients.
For engineers reviewing the SMBJ150D-M3/H datasheet, SMBJ150D-M3/H pinout, SMBJ150D-M3/H application, or SMBJ150D-M3/H equivalent, key selection criteria include its unidirectional polarity, ±3.5 % VBR tolerance, low 0.5 μA reverse leakage 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 clamping device that remains non-conductive below VWM (150 V) and rapidly transitions to low-impedance conduction above VBR (min. 170 V), limiting transient voltages to ≤239 V at rated IPPM. Its junction-to-ambient thermal resistance is 125 °C/W on minimum recommended pad layout, supporting reliable operation up to TJ = 150 °C.
The SMBJ150D-M3/H complies with ANSI/IEEE C62.35 surge standards and meets UL 497B recognition (QVGQ2) for protector classification. It is rated for repetitive 0.01 % duty cycle surges and exhibits fast response time (<1 ns), low incremental surge resistance, and MSL Level 1 moisture sensitivity per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 170 V / 182 V at 1 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 239 V at 2.53 A - clamping voltage defines worst-case overvoltage seen by protected circuitry |
| PPPM | 600 W - peak pulse power handling capability with 10/1000 μs waveform, critical for lightning surge immunity |
| ID @ VWM | 0.5 μA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| TJ max. | 150 °C - enables use in high-temperature industrial environments without derating penalties |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height |
Pinout & Package

|---|---|---|
| Anode | Low-side connection point | Connected to ground or lower-potential rail during clamping; forms return path for surge current |
| Cathode | High-side connection point | Connected to protected line (e.g., 150 V supply rail); band-marked end identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Enables precise coordination with system overvoltage thresholds and reduces design margin uncertainty |
| 600 W PPPM (10/1000 μs) | Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow without preconditioning or special handling |
| M3 suffix compliance | Halogens-free, RoHS-compliant, and passes JESD 201 Class 2 whisker test for long-term reliability |
| Low 0.5 μA ID at VWM | Minimizes loading on high-impedance sensor outputs and precision reference circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A-M3/H | Bidirectional variant; symmetric clamping in both polarities; same VWM (150 V), but VBR min/max = 170–182 V applies to both directions | Required where AC-coupled or floating signal lines need protection against bipolar transients (e.g., RS-485, CAN bus) | Select SMBJ150A-M3/H only if bidirectional clamping is required; SMBJ150D-M3/H is optimal for DC rail protection with defined polarity |
| SMCJ150A | Larger SMC (DO-214AB) package; higher 1500 W PPPM rating; same VWM/VBR specs but 2× thermal mass and 50 % higher RθJA derating | Suitable for higher-energy surge environments (e.g., outdoor power supplies) where board space allows larger footprint | Choose SMCJ150A when 600 W is insufficient and PCB layout permits 7.11 mm × 6.22 mm footprint; SMBJ150D-M3/H offers superior density for space-constrained designs |
Compared with SMBJ150A-M3/H and SMCJ150A, the SMBJ150D-M3/H provides optimal balance of compact SMB packaging, precise unidirectional clamping, and industrial-grade reliability - making it ideal for DC power rail protection where polarity is fixed and board area is constrained.

FAQ
What is the clamping voltage of SMBJ150D-M3/H at its rated peak pulse current?
The SMBJ150D-M3/H has a maximum clamping voltage (VC) of 239 V at its rated peak pulse current (IPPM) of 2.53 A, measured using the standardized 10/1000 μs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-power transient event and is confirmed in the Vishay datasheet Document Number 87606, Table on page 2.
Is SMBJ150D-M3/H suitable for bidirectional signal line protection?
No, SMBJ150D-M3/H is a unidirectional TVS diode - it conducts only when the cathode is positive relative to the anode. For bidirectional protection (e.g., RS-485, CAN, or AC-coupled lines), the bidirectional variant SMBJ150A-M3/H must be used. The "D" suffix explicitly denotes unidirectional polarity, and no bidirectional functionality is supported by SMBJ150D-M3/H.
What does the "-M3/H" suffix indicate for SMBJ150D-M3/H?
The "-M3/H" suffix specifies halogen-free, RoHS-compliant construction (M3) and packaging in 7″ diameter plastic tape and reel (H), with a base quantity of 750 units per reel. The M3 designation also confirms compliance with JESD 201 Class 2 whisker testing and UL 94 V-0 flammability rating - all verified in Vishay's official documentation for SMBJ150D-M3/H.
Can SMBJ150D-M3/H replace SMBJ150A-M3/H in a circuit without modification?
No - SMBJ150D-M3/H cannot directly replace SMBJ150A-M3/H without circuit review. While both share identical VWM (150 V) and VBR (170–182 V), SMBJ150D-M3/H is unidirectional and will not suppress negative-going transients. Substitution requires verification of signal polarity, addition of external blocking diodes, or redesign to accommodate asymmetric clamping behavior.
What is the maximum steady-state power dissipation of SMBJ150D-M3/H at 25 °C ambient?
The SMBJ150D-M3/H has a maximum steady-state power dissipation (PD) of 1.0 W at TA = 25 °C, as specified in the "Maximum Ratings" table of the Vishay datasheet. This rating assumes mounting on standard PCB pads; derating is required above 25 °C per the published thermal curve (Fig. 5), with zero dissipation allowed at 150 °C ambient due to its 150 °C TJ max rating.
