Product details
Overview
P6SMB100H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 90–110 V, stand-off voltage of 81.0 V, and clamping voltage of 144 V at 4.3 A peak pulse current. It features glass-passivated junction, AEC-Q101 qualification, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive transients.
For engineers reviewing the P6SMB100H datasheet, P6SMB100H pinout, P6SMB100H application, or P6SMB100H equivalent, key selection criteria include its 144 V clamping performance under 10/1000 µs surge, 5.0 V forward voltage at 50 A, and DO-214AA (SMB) package compatibility with automated SMT assembly in automotive power rail and ECU protection designs.
Technical Context
The P6SMB100H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 90–110 V breakdown range (tested at 1 mA). Its clamping action limits transient-induced voltage to ≤144 V during 10/1000 µs surges up to 4.3 A, with <1 µA leakage at 81.0 V stand-off.
Thermally, it supports operation from −55 °C to +150 °C junction temperature, with RθJC = 10 °C/W and RθJA = 55 °C/W. It delivers 600 W non-repetitive peak pulse power and withstands 100 A 8.3 ms forward surge per JESD201 Class 2 whisker-tested matte tin leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 90 V / 110 V - Ensures reliable avalanche conduction above system nominal voltage while avoiding false triggering |
| VWM | 81.0 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC@IPPM | 144 V @ 4.3 A - Clamped voltage during standardized 10/1000 µs transient, defining protected circuit voltage ceiling |
| PPPSM | 600 W - Peak pulse power handling capability under defined waveform, critical for ISO 7637-2 compliance |
| VF@50 A | 5.0 V - Forward voltage drop during high-current inductive turn-off events, affecting power dissipation in uni-directional clamp paths |
| TJ max | +150 °C - Enables placement near hot components (e.g., power MOSFETs, DC-DC converters) without derating |
| Package | DO-214AA (SMB) - Standardized 2-pin surface-mount outline with 0.090 g mass and UL 94V-0 molding compound |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Same DO-214AA package; bidirectional variant with symmetric 100 V VBR; 600 W rating; VC = 166 V @ 3.6 A | Required where AC-coupled or bipolar transients dominate (e.g., CAN bus, RS-485 lines) | Select SMBJ100A only if bidirectional clamping is needed; P6SMB100H offers lower VC and higher IPPM for unidirectional DC rails. |
| 1.5SMC100A | Higher power (1500 W); same VBR range (90–110 V); larger DO-214AB (SMC) package; VC = 158 V @ 9.5 A | Suitable for systems requiring higher surge margin or legacy SMC footprint compatibility | Choose 1.5SMC100A when 1500 W pulse handling is mandated; P6SMB100H saves board space and cost for 600 W-class protection. |
Compared with SMBJ100A and 1.5SMC100A, the P6SMB100H delivers optimal balance of compact SMB footprint, 144 V clamping, and AEC-Q101 qualification-making it preferred for space-constrained, automotive-grade 24 V DC rail protection where unidirectional surge directionality is known.

FAQ
What is the breakdown voltage range of the P6SMB100H?
The P6SMB100H has a specified breakdown voltage (VBR) range of 90 V to 110 V, measured at 1 mA test current. This range ensures consistent avalanche initiation across manufacturing lots and temperature extremes, enabling reliable overvoltage protection for 24 V and 48 V systems where nominal rail voltages may vary. The P6SMB100H achieves this performance using a glass-passivated silicon junction.
Does the P6SMB100H meet automotive qualification standards?
Yes, the P6SMB100H is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b transient immunity requirements. These qualifications validate its suitability for under-hood and ECU applications subject to harsh electrical environments. The P6SMB100H also complies with JESD201 Class 2 whisker testing and moisture sensitivity level 1, supporting standard SMT reflow without pre-bake.
What is the clamping voltage of the P6SMB100H under standard surge conditions?
The P6SMB100H exhibits a maximum clamping voltage (VC) of 144 V when subjected to a 10/1000 µs waveform peak pulse current of 4.3 A. This value defines the upper voltage limit imposed on protected circuitry during standardized transients and is critical for ensuring downstream ICs remain within their absolute maximum ratings. The P6SMB100H achieves this with <1 µA leakage at its 81.0 V stand-off voltage.
Is the P6SMB100H unidirectional or bidirectional?
The P6SMB100H is a unidirectional TVS diode, indicated by the absence of "CAH" or "CH" suffix and confirmed by its single-polarity marking (cathode band) and forward voltage specification (VF = 5.0 V at 50 A). It conducts only in reverse bias above VBR and blocks forward current up to its 100 A 8.3 ms surge rating. Bidirectional variants like P6SMB100AH require explicit CAH suffix designation.
What package type does the P6SMB100H use, and what are its mechanical advantages?
The P6SMB100H uses the DO-214AA (SMB) surface-mount package: a low-profile, 2-pin outline with UL 94V-0 flammability-rated molding compound and matte tin-plated leads. Its 0.090 g mass and J-STD-002-compliant terminations support high-yield automated placement and reflow. The SMB footprint enables dense PCB layouts in space-constrained modules such as ADAS sensors and body control units-key advantages of the P6SMB100H over larger SMC or axial packages.
