Product details
Overview
P6KE62AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in DC power rails and signal lines. It features a nominal breakdown voltage of 62 V, maximum clamping voltage of 85.0 V at 7.4 A peak surge current, stand-off voltage of 53.0 V, and low dynamic impedance for fast response to ESD and lightning-induced transients - deployed in automotive body control modules and industrial PLC I/O protection.
For engineers reviewing the P6KE62AH datasheet, P6KE62AH pinout, P6KE62AH application, or P6KE62AH equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility with legacy through-hole layouts, 175°C junction temperature rating, and verified clamping performance under 10/1000 µs surge waveforms.
Technical Context
The P6KE62AH operates as a silicon avalanche diode with unidirectional polarity, activated only during reverse-biased overvoltage events. Its breakdown voltage range (58.9–65.1 V) ensures reliable triggering above system operating voltage while maintaining <1 µA leakage at 53.0 V stand-off.
It delivers 600 W peak pulse power per 10/1000 µs waveform, with thermal derating above 25°C ambient and junction temperature limits up to 175°C. The device exhibits a VBR temperature coefficient of 0.104 %/°C and typical response time under 1.0 ps from 0 V to VBR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single 10/1000 µs surges without failure in automotive load-dump or inductive switching events |
| Breakdown Voltage VBR | 58.9–65.1 V - tight tolerance ensures predictable turn-on margin above 53.0 V DC rail |
| Clamping Voltage VC | 85.0 V @ 7.4 A - limits downstream IC stress to safe levels during 10/1000 µs transients |
| Stand-Off Voltage VWM | 53.0 V - supports continuous operation on 48 V nominal systems with 10% margin |
| Leakage Current ID | <1 µA @ 53.0 V - negligible standby power loss in always-on circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ60A | Same DO-214AC (SMA) package; 60 V VBR min, 96.8 V VC @ 6.2 A; lower peak power (400 W) | Not AEC-Q101 qualified; suited for commercial-grade industrial but not automotive front-end protection | Select when space-constrained SMT layout required and AEC-Q101 not mandated |
| ON Semiconductor 1.5KE62A | Same DO-204AC (DO-15) package; identical 62 V nominal rating; 85 V VC @ 7.4 A; 1500 W peak power | Higher surge capacity enables longer-duration transients; larger thermal mass requires adjusted PCB copper area | Choose for enhanced ruggedness in harsh environments where 1500 W capability justifies footprint and cost increase |
Compared with SMAJ60A and 1.5KE62A, the P6KE62AH uniquely balances AEC-Q101 compliance, through-hole DO-15 compatibility, and 600 W clamping in a cost-optimized automotive-qualified package - making it optimal for legacy-replacement and new BCM designs requiring qualification traceability.

FAQ
What is the clamping voltage of the P6KE62AH under standard 10/1000 µs surge conditions?
The P6KE62AH has a maximum clamping voltage (VC) of 85.0 V when subjected to a 7.4 A peak surge current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components experience no more than 85.0 V during standardized surge events - critical for protecting 60 V-rated MOSFETs and 5 V/3.3 V logic interfaces in automotive and industrial systems.
Is the P6KE62AH suitable for bidirectional transient suppression?
No, the P6KE62AH is a unidirectional TVS diode, indicated by the "H" suffix (AEC-Q101 qualified) and absence of "CA" or "C" designation. It conducts only in reverse bias above its breakdown voltage and must be oriented with cathode toward the protected line. For bidirectional protection, select P6KE62CA or equivalent symmetric devices - the P6KE62AH will not suppress positive-going transients on grounded lines.
Does the P6KE62AH require heatsinking in typical PCB layouts?
The P6KE62AH does not require external heatsinking for single-event surge suppression due to its short pulse duration (≤1 ms). However, for repetitive surge duty cycles or elevated ambient temperatures (>75°C), PCB copper pour ≥5 × 5 mm per lead is recommended per datasheet derating curves. Its 5 W steady-state power dissipation rating at 75°C assumes this copper area - insufficient copper may cause thermal runaway during sustained overvoltage.
How does the AEC-Q101 qualification of the P6KE62AH impact automotive design validation?
The AEC-Q101 qualification of the P6KE62AH means it has passed accelerated stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD - eliminating the need for additional component-level qualification in automotive ECUs. Designers can directly reference TSC's AEC-Q101 certificate for P6KE62AH in PPAP submissions, reducing validation time and cost for BCM, lighting, and ADAS subsystems.
What is the leakage current specification for the P6KE62AH at its rated stand-off voltage?
The P6KE62AH specifies maximum reverse leakage current (ID) of less than 1 µA at its stand-off voltage of 53.0 V and 25°C ambient. This ultra-low leakage ensures minimal power loss in always-on automotive modules such as door lock controllers or CAN wake-up receivers - preserving battery life over extended vehicle parking periods without compromising clamping responsiveness.
