Product details
Overview
P6KE82CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It features a nominal breakdown voltage of 82V, clamps transients to ≤113V at 5.5A peak pulse current, and delivers <1μA reverse leakage at 70.1V standoff voltage - enabling robust ESD and lightning-induced surge protection in 12V/24V systems.
For engineers reviewing the P6KE82CAH datasheet, P6KE82CAH pinout, P6KE82CAH application, or P6KE82CAH equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, bidirectional clamping symmetry, and verified 10/1000μs waveform surge capability - critical for automotive body control modules, industrial PLC I/O protection, and DC power supply input stages.
Technical Context
The P6KE82CAH implements a silicon avalanche diode structure optimized for fast transient response (<5.0ns for bidirectional operation) and low dynamic impedance. Its bidirectional configuration ensures symmetrical clamping in both polarities without external polarity management, supporting unidirectional or bidirectional signal/power line protection without circuit redesign.
Rated for 600W non-repetitive peak pulse power at 10/1000μs, it operates across -55°C to +175°C junction temperature range and maintains stable VBR with 0.105%/°C temperature coefficient - ensuring predictable clamping performance under thermal stress in engine bay or industrial enclosures.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | 600W rating, 85V VBR min (80.8–89.2V), DO-214AA package - 30% smaller footprint, higher thermal resistance | Preferred for space-constrained PCBs but requires derating above 75°C ambient | Select SMBJ85CA when board area is limited and thermal management permits lower power density |
| 1.5KE82CA | 1500W rating, same 82V nominal, DO-201AD package - larger size, higher surge margin, slower response (~10ns) | Suitable for legacy designs requiring higher energy absorption, not AEC-Q101 qualified | Choose 1.5KE82CA only if system-level testing confirms need for >600W surge handling and automotive qualification is not required |
Compared with SMBJ85CA and 1.5KE82CA, the P6KE82CAH uniquely balances AEC-Q101 compliance, DO-15 manufacturability, and precise 77.9–86.1V VBR tolerance - making it optimal for new automotive and industrial designs where qualification, consistency, and standard through-hole assembly are mandatory.

FAQ
What is the maximum clamping voltage of the P6KE82CAH at its rated peak pulse current?
The P6KE82CAH has a maximum clamping voltage (VC) of 113V at 5.5A peak pulse current (IPP), measured under the standard 10/1000μs waveform. This value ensures downstream components rated for ≤120V operation remain within safe operating limits during surge events. The P6KE82CAH achieves this clamping performance while maintaining low dynamic impedance and sub-5ns response time.
Is the P6KE82CAH suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the P6KE82CAH is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirming compliance with stress tests including high-temperature reverse bias, temperature cycling, and highly accelerated life testing. This makes the P6KE82CAH appropriate for under-hood and chassis-mounted automotive systems where reliability under thermal and mechanical stress is mandatory.
How does the bidirectional configuration of the P6KE82CAH affect PCB layout and circuit design?
The P6KE82CAH's bidirectional architecture eliminates polarity sensitivity - both terminals are functionally identical, allowing unrestricted orientation during placement. This simplifies PCB routing, removes risk of reverse installation, and supports direct integration on AC-coupled lines, differential buses, or floating power domains without additional diodes or orientation checks. The P6KE82CAH thus reduces BOM count and assembly complexity versus unidirectional alternatives.
What is the standoff voltage (VWM) of the P6KE82CAH, and why is it important for system design?
The P6KE82CAH has a maximum standoff voltage (VWM) of 70.1V, meaning it remains in high-impedance state below this DC or RMS voltage - drawing less than 1μA leakage current. This parameter ensures reliable operation in 60V nominal systems (e.g., 24V industrial rails with 200% tolerance) without unnecessary power loss or false triggering. Selecting a TVS with appropriate VWM prevents premature conduction while retaining sufficient margin above normal operating voltage.
Can the P6KE82CAH replace older P6KE82C parts in existing designs?
Yes, the P6KE82CAH is a direct replacement for P6KE82C with identical electrical specifications, DO-204AC package, and pin-compatible form factor - plus added AEC-Q101 qualification and halogen-free construction. No PCB or schematic changes are needed; the "H" suffix denotes enhanced reliability and environmental compliance. The P6KE82CAH maintains full backward compatibility while improving supply chain assurance and automotive eligibility.
