Product details
Overview
P6KE82 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 82 V, clamps transients to ≤118 V at 5.3 A peak surge current, and delivers low dynamic impedance with <1 μA leakage at 66.4 V standoff voltage - deployed in automotive body electronics, industrial PLC I/O modules, and AC/DC adapter input stages.
For engineers reviewing the P6KE82 datasheet, P6KE82 pinout, P6KE82 application, or P6KE82 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, 10/1000 μs surge rating, unidirectional polarity marking, and AEC-Q101 qualification status (P6KE82H variant only).
Technical Context
The P6KE82 operates as a silicon avalanche diode optimized for fast clamping of ESD and lightning-induced transients. Its junction structure enables sub-nanosecond response (<1 ps from 0 V to VBR) and maintains stable VBR (73.8–90.2 V) under 1 mA test current, with temperature coefficient of 0.105 %/°C.
It is rated for non-repetitive 600 W peak pulse power per 10/1000 μs waveform, derates linearly above 25 °C ambient, and supports maximum junction temperature of 175 °C. The device exhibits 118 V clamping voltage at 5.3 A IPP, with 66.4 V maximum standoff voltage and <1 μA reverse leakage at rated VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 73.8 V / 90.2 V - defines guaranteed avalanche initiation range under 1 mA test current |
| VWM | 66.4 V - maximum continuous reverse operating voltage before significant leakage |
| VC @ IPP | 118 V at 5.3 A - clamping voltage limiting downstream circuit stress during surge events |
| PPK | 600 W - peak pulse power handling per 10/1000 μs waveform, critical for lightning immunity |
| IR @ VWM | <1 μA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJMAX | 175 °C - enables reliable operation in under-hood automotive and industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94V-0 molding compound |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking for unidirectional polarity. 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 connection point | Connected to ground or return path; forms clamping loop with cathode |
| Cathode | High-side connection point | Marked with band; connects to protected line (e.g., 24 V rail or CAN_H); conducts during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche clamping speed | <1 ps response from 0 V to VBR - prevents nanosecond-scale voltage overshoot in sensitive analog inputs |
| Surge robustness | 600 W peak power at 10/1000 μs - meets IEC 61000-4-5 Level 4 (4 kV) for industrial equipment |
| Leakage control | <1 μA at 66.4 V - avoids false triggering and preserves battery life in always-on systems |
| Thermal reliability | 175 °C max junction temperature - supports operation in engine control units and motor drives |
| Material compliance | RoHS-compliant and halogen-free per IEC 61249-2-21 - satisfies automotive and EU environmental mandates |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|

IC Role / Device Role: Parallel-connected TVS across output capacitor to absorb stored inductive energy. Use Value: Absorbs 600 W surges without degradation, ensuring compliance with UL 62368-1 transient immunity requirements. |
Use Scenario: Protecting MOSFET gate drivers and current-sense amplifiers from inductive kickback in LED string switching. IC Role / Device Role: Clamp placed across half-bridge drain-source nodes to limit VDS overshoot. Use Value: Enables use of lower-voltage-rated 60 V MOSFETs by capping transients at 118 V, reducing BOM cost and footprint. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ85A | 85 V VBR min (80.8–89.2 V), 400 W PPK, SMA package | Lower surge rating and surface-mount form factor - suited for space-constrained PCBs but not direct replacement for axial DO-15 layout | Select when board area is limited and 400 W surge margin suffices; requires re-layout |
| ON Semiconductor 1.5KE82A | 82 V nominal, same DO-204AC package, 1500 W PPK, higher clamping (125 V) | Higher power handling but looser clamping - better for severe lightning zones, less ideal for low-voltage IC protection | Choose for enhanced surge margin where 125 V clamping is acceptable; identical footprint enables drop-in upgrade |
Compared with SMAJ85A, P6KE82 offers higher surge capacity and axial through-hole mounting; versus 1.5KE82A, it provides tighter clamping (118 V vs. 125 V) at lower peak power - optimizing protection for voltage-sensitive 24 V logic interfaces.

FAQ
What is the breakdown voltage range for P6KE82?
The P6KE82 has a guaranteed breakdown voltage range of 73.8 V to 90.2 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures consistent avalanche initiation across manufacturing lots and temperature extremes, making P6KE82 suitable for designs requiring predictable clamping onset in 24 V and 48 V systems.
Is P6KE82 RoHS and halogen-free compliant?
Yes, P6KE82 is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the pure tin-plated leads comply with J-STD-002 solderability requirements - confirming full environmental compliance for automotive and industrial deployments where P6KE82 is used.
Does P6KE82 have AEC-Q101 qualification?
The base P6KE82 is not AEC-Q101 qualified; however, the P6KE82H variant (ordering code with "H" suffix) is AEC-Q101 qualified per Version P2203 documentation. Engineers specifying P6KE82 for automotive applications must select P6KE82H to meet vehicle-grade reliability requirements.
What is the clamping voltage of P6KE82 at its rated surge current?
P6KE82 clamps to a maximum of 118 V at 5.3 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is verified per JEDEC test conditions and defines the upper voltage limit imposed on protected circuits during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Can P6KE82 be used in bidirectional configurations?
No, P6KE82 is a unidirectional TVS diode intended for DC line protection with defined anode/cathode polarity. For bidirectional protection, engineers must select the CA-suffixed variant (e.g., P6KE82CA) or equivalent bipolar part - using P6KE82 in AC or floating applications risks failure due to reverse conduction outside its design envelope.
