Product details
Overview
P6SMB62AH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 62V, clamping voltage of 85.0V at 7.4A peak pulse current, and stand-off voltage of 53.0V. It features glass passivated junction, AEC-Q101 qualification, and DO-214AA (SMB) package for automotive and industrial overvoltage protection.
For engineers reviewing the P6SMB62AH datasheet, P6SMB62AH pinout, P6SMB62AH application, or P6SMB62AH equivalent, this device is selected for high-reliability ESD and surge protection in power supply rails, automotive control modules, and industrial sensor interfaces where low leakage (<1µA @ 53V), fast response (<1.0ps), and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance are required.
Technical Context
The P6SMB62AH operates as a unidirectional avalanche diode, conducting only in reverse bias above its specified VBR (58.9–65.1V) to clamp transients. Its 600W peak pulse power rating (10/1000μs waveform) and 85.0V clamping voltage at 7.4A define its energy-handling capability in real-world surge events.
Thermal performance is characterized by RθJC = 10°C/W and RθJA = 55°C/W, supporting operation from –55°C to +150°C junction temperature. It exhibits <1µA reverse leakage at VWM = 53.0V and a VBR temperature coefficient of 0.104%/°C, ensuring stable clamping across automotive temperature ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | VBR = 71.1–78.6V; VC = 103V @ 5.8A; same DO-214AA package | Higher clamping voltage reduces margin for 60V-rated downstream components | Select when higher VBR tolerance is acceptable and system VMAX > 103V |
| 1.5SMC62A | VBR = 68.9–76.2V; VC = 101V @ 5.9A; DO-214AB (SMC) package, larger footprint | Larger SMC package requires PCB redesign; higher thermal mass suits high-duty-cycle environments | Choose when board space permits larger package and higher steady-state power dissipation (5W vs. 3W) is needed |
Compared with SMBJ64A and 1.5SMC62A, the P6SMB62AH offers tighter VBR tolerance (58.9–65.1V), lower clamping voltage (85.0V), and optimized thermal resistance (RθJA = 55°C/W) for compact automotive modules where voltage margin and layout density are critical.

FAQ
What is the maximum clamping voltage of the P6SMB62AH under standard 10/1000μs surge conditions?
The P6SMB62AH has a maximum clamping voltage (VC) of 85.0V when subjected to its rated peak pulse current of 7.4A using the standard 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream circuitry. The P6SMB62AH maintains this clamping performance across its full operating temperature range of –55°C to +150°C.
Is the P6SMB62AH suitable for bidirectional transient suppression applications?
No, the P6SMB62AH is a unidirectional TVS diode intended for DC circuits with defined polarity. For bidirectional protection, Taiwan Semiconductor specifies parts with "CAH" suffix (e.g., P6SMB62CAH). The P6SMB62AH features a cathode band marking and conducts only in reverse bias; using it in AC or bipolar signal paths would result in forward conduction and failure.
Does the P6SMB62AH meet automotive qualification standards?
Yes, the P6SMB62AH is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements. It is rated for junction temperatures from –55°C to +150°C and manufactured under IATF 16949-compliant processes. These qualifications confirm its suitability for under-hood and chassis-mounted automotive electronics where reliability under harsh electrical and thermal stress is mandatory.
What is the reverse leakage current specification for the P6SMB62AH at its stand-off voltage?
The P6SMB62AH exhibits a maximum reverse leakage current (IR) of 1µA when biased at its rated stand-off voltage (VWM) of 53.0V. This ultra-low leakage is verified at TA = 25°C and supports low-power system designs, especially in battery-operated or always-on automotive modules where quiescent current must remain minimal. The P6SMB62AH maintains <5µA leakage up to 80% of VWM.
How does the thermal performance of the P6SMB62AH compare to similar SMB-package TVS diodes?
The P6SMB62AH has a junction-to-ambient thermal resistance (RθJA) of 55°C/W and junction-to-case resistance (RθJC) of 10°C/W, measured on standard FR-4 PCB with recommended pad layout. This matches industry benchmarks for DO-214AA devices and enables reliable operation at full 600W pulse rating with ≤10°C junction rise per watt under typical mounting conditions. The P6SMB62AH's thermal design supports repeated surge events without derating in most automotive PCB layouts.
