Product details
Overview
P6SMB10 from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with breakdown voltage range 9.0–11.0 V, stand-off voltage 8.10 V, and clamping voltage 15.0 V at 42 A peak pulse current - designed for overvoltage protection in low-voltage DC power rails such as AC/DC adapters and SMPS input stages.
For engineers reviewing the P6SMB10 datasheet, P6SMB10 pinout, P6SMB10 application, or P6SMB10 equivalent, key selection criteria include its 8.10 V working voltage, 15.0 V clamping performance at 42 A, unidirectional polarity, 1.0 mA test current, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b automotive transients.
Technical Context
The P6SMB10 operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 9.0–11.0 V breakdown range under 1.0 mA test current. It clamps transient energy to ≤15.0 V at 42 A (10/1000 µs waveform), with <1 µA leakage at 8.10 V and fast response time <1.0 ps from 0 V to VBR(min).
Thermally, it features RθJC = 10 °C/W and RθJA = 55 °C/W, rated for TJ = –55 to +150 °C, and meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1 - enabling reliable automated placement and reflow soldering in high-volume manufacturing.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Bi-directional variant; VBR = 11.1–12.3 V; VC = 17.0 V at 35.3 A; same DO-214AA package | Required where bidirectional protection (e.g., data lines, AC-coupled signals) is needed instead of DC-rail clamping | Select SMBJ10A only if symmetrical clamping in both polarities is required; P6SMB10 offers tighter VBR tolerance and lower VC for unidirectional use. |
| 1.5SMC10A | Same VBR range but in larger DO-214AB (SMC) package; VC = 16.7 V at 35.7 A; higher thermal mass | Better suited for high-temperature or high-duty-cycle surge environments where SMB footprint is insufficient | Choose 1.5SMC10A when board space allows and thermal derating margin is critical; P6SMB10 provides identical electrical specs in compact SMB form factor. |
Compared with SMBJ10A and 1.5SMC10A, P6SMB10 delivers lower clamping voltage (15.0 V vs. ≥16.7 V) and tighter breakdown tolerance (9.0–11.0 V vs. 11.1–12.3 V or 10.0–11.1 V) in the smallest DO-214AA footprint - optimizing protection density for space-constrained 12 V rail designs.

FAQ
What is the breakdown voltage range of the P6SMB10?
The P6SMB10 has a specified breakdown voltage (VBR) range of 9.0 V to 11.0 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent avalanche initiation across production units while allowing design margin for 12 V nominal systems. The P6SMB10 is tested and binned to meet this specification under controlled conditions.
Is the P6SMB10 unidirectional or bidirectional?
The P6SMB10 is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its single cathode band marking and forward voltage (VF) specification of 3.5 V at 50 A. It protects against positive-going transients on DC lines and must be oriented with cathode toward the protected voltage rail. The P6SMB10 does not conduct in reverse bias until breakdown occurs.
What is the maximum clamping voltage of the P6SMB10 under surge conditions?
The P6SMB10 exhibits a maximum clamping voltage (VC) of 15.0 V when subjected to a 10/1000 µs waveform peak pulse current of 42 A. This value is guaranteed across temperature and process variation, and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB10 achieves this performance with no external components or biasing.
Does the P6SMB10 meet automotive transient standards?
Yes, the P6SMB10 meets ISO 7637-2 requirements for Pulse 1, 2a, 2b, 3a, and 3b, making it suitable for 12 V automotive subsystems such as infotainment power supplies and body control modules. Its 600 W peak pulse rating, low clamping voltage, and –55 to +150 °C operating range align with automotive environmental and reliability expectations. The P6SMB10 is not AEC-Q200 qualified but satisfies the electrical test criteria of the standard.
What package type does the P6SMB10 use, and is it RoHS compliant?
The P6SMB10 uses the DO-214AA (SMB) surface-mount package with matte tin-plated leads and UL 94V-0 mold compound. It is RoHS compliant and halogen-free per IEC 61249-2-21, with moisture sensitivity level (MSL) 1 per J-STD-020 - enabling lead-free reflow without baking. The P6SMB10's SMB footprint supports high-density PCB layouts and automated pick-and-place assembly.
