Product details
Overview
P6SMB150AH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a 143–158 V breakdown voltage (VBR), 128 V stand-off voltage (VWM), and 207 V clamping voltage (VC) at 3.0 A peak pulse current. It delivers automotive-grade ESD and surge protection in DO-214AA (SMB) package for power supply rails and interface lines.
For engineers reviewing the P6SMB150AH datasheet, P6SMB150AH pinout, P6SMB150AH application, or P6SMB150AH equivalent, key selection criteria include its AEC-Q101 qualification, 1.0 mA test current, <1 µA leakage at VWM, 10/1000 µs waveform capability, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b.
Technical Context
The P6SMB150AH operates as a unidirectional avalanche diode, designed to clamp transient overvoltages above its VWM of 128 V while maintaining low leakage (<1 µA). Its junction-to-ambient thermal resistance is 55 °C/W, enabling reliable operation up to TJ = 150 °C under pulsed conditions.
It features glass-passivated junction construction, meets JESD201 Class 2 whisker resistance, and is rated for 100 A non-repetitive forward surge (IFSM) per 8.3 ms half-sine wave - critical for load-dump immunity in 24 V automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V - defines minimum and maximum voltage at which device enters avalanche conduction at 1.0 mA test current |
| VWM | 128 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 207 V at 3.0 A - clamped voltage during 10/1000 µs surge, limiting stress on downstream circuitry |
| PPPSM | 600 W - peak pulse power handling per single 10/1000 µs transient, derated above 25 °C ambient |
| IR @ VWM | <1 µA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | 150 °C - maximum junction temperature rating supports under-hood automotive deployment |
| Package | DO-214AA (SMB) - industry-standard surface-mount outline with 0.090 g mass and J-STD-002 solderability |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, cathode band marking polarity, UL 94V-0 flammability rating, and JEDEC-compliant mechanical dimensions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Same DO-214AA package, identical VBR range (143–158 V), but rated for 600 W with 1.0 mA IT and 1 µA IR - functionally aligned | Identical ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance; minor differences in RθJA (50 vs. 55 °C/W) | Select SMBJ150A if tighter thermal budget requires marginally better junction-to-ambient dissipation |
| 1.5SMC150A | Larger DO-214AB (SMC) package (7.11 × 6.22 mm vs. 4.57 × 3.94 mm), same electrical specs, higher PPPSM (1500 W) but not needed for 600 W use cases | Requires PCB layout change due to larger footprint and higher mounting height; suitable only where board space permits | Choose 1.5SMC150A only when legacy designs mandate SMC footprint or require headroom beyond 600 W |
Compared with SMBJ150A and 1.5SMC150A, the P6SMB150AH offers identical clamping performance in a smaller SMB package, optimized for high-density automotive and industrial PCBs where space and weight are constrained.

FAQ
What is the breakdown voltage tolerance of the P6SMB150AH?
The P6SMB150AH has a specified breakdown voltage (VBR) range of 143 V to 158 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 150 V rating. This tight spread ensures consistent clamping behavior across production lots and supports reliable design margining in 24 V and 48 V systems.
Is the P6SMB150AH suitable for bidirectional transient protection?
No - the P6SMB150AH is a unidirectional TVS diode, intended for clamping positive transients on DC lines referenced to ground. For bidirectional protection, Taiwan Semiconductor specifies the P6SMB150CAH variant (with CAH suffix), which provides symmetrical clamping in both polarities and uses different marking (NLJ).
Does the P6SMB150AH meet automotive qualification standards?
Yes - the P6SMB150AH is explicitly AEC-Q101 qualified and tested per ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms. Its glass-passivated junction, MSL Level 1 rating, and -55 °C to +150 °C operating range confirm suitability for under-hood and body-control module applications.
What is the maximum clamping voltage of the P6SMB150AH under surge conditions?
The P6SMB150AH exhibits a maximum clamping voltage (VC) of 207 V when subjected to its rated 3.0 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is guaranteed across temperature and lifetime, ensuring downstream components see no more than 207 V during worst-case transients.
How does the P6SMB150AH compare to older P6SMB150H in terms of leakage and clamping?
The P6SMB150AH improves upon the base P6SMB150H with tighter VBR tolerance (143–158 V vs. 135–165 V) and lower clamping voltage (207 V vs. 215 V at same IPPM). Both share identical VWM (128 V) and leakage (<1 µA), but the AH variant delivers enhanced precision and reduced stress on protected circuitry.
