Product details
Overview
P6KE82H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in power supply inputs, automotive ECUs, and industrial control interfaces. It features a nominal breakdown voltage of 82 V, clamping voltage of 118 V at 5.3 A peak surge current, and stand-off voltage of 66.4 V - enabling robust ESD and lightning-induced surge suppression in 24–48 V systems.
For engineers reviewing the P6KE82H datasheet, P6KE82H pinout, P6KE82H application, or P6KE82H equivalent, this device is selected for high-energy transient immunity in DC power rails where fast response (<1 ps), low leakage (<1 µA @ 66.4 V), and AEC-Q101 qualification are required for automotive-grade reliability.
Technical Context
The P6KE82H operates as a unidirectional avalanche diode with a single-die DO-204AC (DO-15) package. Its junction exhibits a temperature coefficient of 0.105 %/°C and maximum junction temperature of +175 °C, supporting operation in under-hood automotive environments.
It delivers 600 W non-repetitive peak pulse power per 10/1000 µs waveform, with clamping performance validated at 118 V (VC) under 5.3 A (IPP) surge current - ensuring predictable voltage limiting during fast transients such as load dump or inductive switching events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 73.8 V / 90.2 V - defines guaranteed avalanche conduction onset range at 1 mA test current; ensures consistent turn-on across production lots |
| VWM | 66.4 V - maximum continuous reverse operating voltage; sets safe DC rail margin before leakage rises above 1 µA |
| VC @ IPP | 118 V @ 5.3 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient stress level |
| PPK | 600 W - peak pulse power handling capability; enables survival of ISO 7637-2 Pulse 1/2/5a surges without degradation |
| IR @ VWM | <1 µA - ultra-low reverse leakage at rated stand-off; minimizes standby power loss in always-on systems |
| TJMAX | +175 °C - maximum junction temperature; supports placement near heat-generating components in engine control modules |
| AEC-Q101 | Qualified - certified for automotive electronic components per stress test requirements including HTOL, TCT, and HAST |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to system ground or return path; forms current sink during transient clamp event |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., battery rail); conducts avalanche current toward anode when VAK exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity bias, and high-temperature operating life |
| 600 W surge rating (10/1000 µs) | Withstands ISO 7637-2 Pulse 5a (load dump) up to 120 V without failure in 12 V systems |
| Clamping voltage ≤118 V | Limits downstream IC stress to safe levels during 5.3 A transient events - critical for protecting 100 V-rated MOSFETs and gate drivers |
| Response time <1 ps | Activates faster than most microsecond-scale transients, preventing voltage overshoot before protection engages |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and UL 94V-0 flammability standard - suitable for enclosed industrial enclosures |
Applications
| Automotive Power Input Protection | Industrial PLC I/O Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85A | Bi-directional configuration; 85 V standoff; 100 W lower peak power (500 W) | Requires polarity-aware layout; less suited for unidirectional DC rails with strict leakage limits | Select only if bidirectional protection is needed and 500 W rating suffices for system-level surge profile |
| 1.5KE82A | Same unidirectional function but higher leakage (5 µA @ 66.4 V); no AEC-Q101 qualification | Lacks automotive qualification; unsuitable for OEM ECU designs requiring PPAP documentation | Acceptable for cost-sensitive industrial applications where AEC-Q101 is not mandated |
Compared with SMBJ85A and 1.5KE82A, P6KE82H offers superior automotive qualification, lower leakage, and higher surge margin - making it the preferred choice for safety-critical 24–48 V power rail protection where long-term reliability and regulatory compliance are mandatory.

FAQ
What is the key difference between P6KE82H and P6KE82A?
The P6KE82H is AEC-Q101 qualified and intended for automotive applications, whereas P6KE82A lacks that qualification and is targeted at industrial use. Both share identical electrical specs - 73.8–90.2 V breakdown, 66.4 V stand-off, and 118 V clamping - but P6KE82H undergoes additional stress testing per automotive reliability standards. P6KE82H remains the recommended part for any design requiring formal automotive qualification.
Does P6KE82H support bidirectional transient suppression?
No, P6KE82H is a unidirectional TVS diode - it conducts only when cathode voltage exceeds anode voltage by ≥73.8 V. For bidirectional protection, select P6KE82CA or P6KE82A (which is also unidirectional) - note that "A" suffix denotes tighter VBR tolerance, not polarity. True bidirectional variants carry "C" or "CA" suffixes and have symmetric breakdown in both directions.
What is the maximum ambient temperature for continuous operation of P6KE82H?
P6KE82H supports continuous operation up to +125 °C ambient when mounted on 5 × 5 mm copper pads per terminal, based on derating curves in the datasheet. At 75 °C ambient, its steady-state power dissipation is rated at 5 W. Junction temperature must remain ≤+175 °C, so thermal design must account for power dissipation during infrequent surge events and ambient conditions.
Can P6KE82H be used in parallel to increase surge current handling?
No - P6KE82H should not be paralleled due to mismatch in VBR (±6.2 V spread) causing uneven current sharing and potential thermal runaway. To handle higher surge currents, select a higher-power TVS like 15KP82A or implement staged protection with upstream fusing and downstream MOVs. Always verify layout parasitics and ensure single-point grounding for optimal clamping performance.
Is P6KE82H compliant with RoHS and halogen-free standards?
Yes, P6KE82H is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and leads are pure tin-plated per J-STD-002. These attributes make P6KE82H suitable for environmentally regulated markets including EU automotive and industrial equipment, with full material declarations available upon request.
