Product details
Overview
P4SMA62CH from Taiwan Semiconductor is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode with a 50.2V working stand-off voltage, 55.8–68.2V breakdown range at 1mA, and 89.0V maximum clamping voltage under 10/1000μs surge. It is AEC-Q101 qualified and designed for automotive-grade DC/DC converter input protection.
For engineers reviewing the P4SMA62CH datasheet, P4SMA62CH pinout, P4SMA62CH application, or P4SMA62CH equivalent, this device offers verified bidirectional-capable packaging (CH suffix), ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, sub-1ps response time, and <1μA leakage above 10V - critical for robust ESD and load-dump suppression in harsh environments.
Technical Context
The P4SMA62CH employs a glass-passivated silicon junction optimized for fast transient suppression in automotive and industrial power rails. Its DO-214AC (SMA) package supports automated placement and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards.
It operates across –55°C to +150°C junction temperature, with peak pulse power rated at 400W (10/1000μs), 40A non-repetitive forward surge capability, and a temperature coefficient of VBR at 0.104%/°C - enabling stable clamping performance over wide thermal excursions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | DO-214AA package; 58V VWM, 64.4–71.4V VBR, 93.6V VC; 600W rating | Higher power rating but larger footprint; less suitable for space-constrained automotive modules | Select when higher surge margin is required and PCB area allows SMB package |
| 1.5SMC58A | DO-214AB package; same VWM/VBR range; 58V VWM, 64.4–71.4V VBR, 93.6V VC; 1500W rating | Substantially higher PPPM but 3× larger size and 0.33g weight - incompatible with SMA-reflow profiles | Choose only for legacy designs requiring 1.5kW surge handling and no space constraints |
Compared with SMBJ58A and 1.5SMC58A, the P4SMA62CH provides optimal balance of AEC-Q101 compliance, DO-214AC footprint compatibility, and precise 50.2V standoff - making it preferred for new automotive and compact industrial designs where board space and qualification rigor are prioritized over raw power headroom.

FAQ
What is the polarity configuration of the P4SMA62CH?
The P4SMA62CH is a unidirectional TVS diode with cathode band marking. Its anode connects to the protected line and cathode to ground, enabling clamping only during reverse-voltage transients. This configuration ensures minimal leakage during normal operation while providing precise 50.2V standoff and 89.0V clamping - essential for protecting sensitive 60V-rated controllers in automotive DC/DC converters using the P4SMA62CH.
Does the P4SMA62CH meet automotive qualification standards?
Yes, the P4SMA62CH is AEC-Q101 qualified and compliant with ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test waveforms. It is rated for –55°C to +150°C junction temperature and undergoes rigorous stress testing including HTOL, temperature cycling, and HAST - confirming suitability for under-hood automotive applications where the P4SMA62CH serves as primary transient protection on 12V/48V power rails.
What is the maximum clamping voltage of the P4SMA62CH under surge conditions?
The P4SMA62CH has a maximum clamping voltage (VC) of 89.0V at IPPM = 4.7A with a 10/1000μs waveform. This value is guaranteed across temperature and ensures downstream components - such as MOSFETs or controllers with 100V absolute maximum ratings - remain within safe operating limits during standardized load-dump events, directly validating the protective function of the P4SMA62CH in real-world deployments.
How does the P4SMA62CH compare to bidirectional variants like P4SMA62CH?
The P4SMA62CH is unidirectional; bidirectional equivalents (e.g., P4SMA62C) use CH suffix but differ in symmetry - the P4SMA62CH clamps only in reverse bias, whereas P4SMA62C clamps identically in both directions. For automotive power rails referenced to ground, the P4SMA62CH offers lower leakage (<1µA) and tighter VBR tolerance, making it preferable unless bipolar surge sources (e.g., floating data lines) require true bidirectional behavior.
What packaging and reel quantity is offered for the P4SMA62CH?
The P4SMA62CH is supplied in DO-214AC (SMA) package on 7,500-piece tape-and-reel format, compatible with standard SMT pick-and-place equipment. The matte tin-plated leads meet J-STD-002 solderability requirements, and moisture sensitivity level is rated at Level 1 (unlimited floor life), simplifying manufacturing flow for high-volume production of boards using the P4SMA62CH.
