Product details
Overview
P6KE82C 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 fast response (<1.0 ps from 0 V to VBR), with <1 μA reverse leakage above 70.1 V stand-off voltage.
For engineers reviewing the P6KE82C datasheet, P6KE82C pinout, P6KE82C application, or P6KE82C equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity marking, 175 °C junction rating, and suitability for automotive EFT/ESD hardening, industrial power supply input stages, and LED driver surge protection per IEC 61000-4-4/5.
Technical Context
The P6KE82C operates as a silicon avalanche diode, leveraging controlled reverse-biased Zener breakdown to clamp transient energy before downstream circuitry sustains damage. Its 10/1000 μs waveform surge rating of 600 W and low dynamic impedance ensure effective suppression of lightning-induced surges and inductive switching spikes.
Designed for unidirectional operation only, it exhibits a specified breakdown voltage range of 73.8–90.2 V at 1 mA test current, a maximum clamping voltage of 118 V at 5.3 A, and a temperature coefficient of VBR of 0.105 %/°C - enabling predictable performance across -55 °C to +175 °C ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 73.8 V / 90.2 V at 1 mA - defines reliable conduction onset window under surge stress |
| VWM | 66.4 V - maximum continuous DC or RMS operating voltage before leakage exceeds 1 μA |
| VC @ IPP | 118 V at 5.3 A - peak clamped voltage during 10/1000 μs surge, limiting stress on protected ICs |
| PPK | 600 W - non-repetitive surge power handling capability per standard 10/1000 μs waveform |
| IR @ VWM | <1 μA - ensures negligible standby power loss and minimal interference in high-impedance circuits |
| TJ max | +175 °C - enables use in under-hood automotive and high-temperature industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with tin-plated leads, UL 94V-0 rated molding |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Leads are pure tin-plated and solderable per J-STD-002; weight ≈ 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry / Surge return path | Connected to system ground or low-side reference; completes clamping loop during transient events |
| Cathode (banded end) | Reverse-biased avalanche node | Connected to protected line (e.g., 24 V rail); conducts when voltage exceeds VBR, shunting surge to ground |
Key Features

|---|---|
| 600 W surge rating (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges without derating in compact layout |
| Clamping voltage ≤118 V | Keeps downstream 80 V-rated MOSFETs and controllers within safe operating area during 5.3 A transients |
| Response time <1.0 ps | Activates faster than most microsecond-scale transients, preventing voltage overshoot before protection engages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ85A | Same DO-214AC package; 85 V VBR min (76.5–93.5 V), 119 V VC @ 5.3 A, 400 W rating | Lower surge rating limits use in high-energy industrial environments; better suited for space-constrained PCBs | Select when board real estate is critical and 400 W surge margin suffices per IEC 61000-4-5 Level 2 |
| ON Semiconductor 1.5KE82C | Same 82 V nominal rating, DO-201AD package; 600 W rating, 118 V VC @ 5.3 A, but higher VWM (67.2 V) | Larger DO-201AD footprint requires layout change; higher thermal mass improves sustained pulse handling | Choose for legacy designs using DO-201AD or where enhanced thermal dissipation is needed in high-ambient zones |
Compared with SMAJ85A and 1.5KE82C, the P6KE82C offers identical surge capability and clamping performance in a smaller DO-15 axial form factor, enabling cost-effective through-hole assembly and compatibility with existing AEC-Q101-compliant automotive harness interfaces.

FAQ
What is the maximum clamping voltage of the P6KE82C under surge conditions?
The P6KE82C has a maximum clamping voltage (VC) of 118 V when subjected to its rated peak pulse current of 5.3 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuitry remains below critical voltage thresholds during transient events. The P6KE82C maintains this clamping performance consistently across its operational temperature range.
Is the P6KE82C suitable for automotive applications?
Yes - the P6KE82C is available in an AEC-Q101 qualified variant (P6KE82CH) that meets stress testing requirements for automotive electronics, including temperature cycling, humidity bias, and mechanical shock. While the base P6KE82C is not AEC-Q101 certified, its 175 °C junction rating, low leakage, and robust surge capability make it appropriate for non-safety-critical automotive subsystems such as lighting and infotainment power inputs.
How does the P6KE82C differ from bidirectional TVS diodes like P6KE82CA?
The P6KE82C is unidirectional and intended for DC line protection with defined polarity (cathode to protected line), whereas P6KE82CA is bidirectional and symmetrical - suitable for AC lines or data lines where voltage polarity reverses. The P6KE82C offers lower leakage (<1 μA at 66.4 V) and faster response (<1.0 ps) than its bidirectional counterpart, which has 5 ns response and higher leakage due to dual-junction structure.
What is the standoff voltage (VWM) rating for the P6KE82C?
The P6KE82C has a maximum working peak reverse voltage (VWM) of 66.4 V, meaning it can be continuously applied across the device without exceeding 1 μA reverse leakage current. This allows safe integration into 48 V or 60 V DC systems where normal operating voltage stays below 66.4 V, while still providing headroom for transient clamping up to 118 V.
Can the P6KE82C be used in parallel for higher surge current handling?
No - the P6KE82C is not recommended for parallel operation due to mismatch in VBR tolerance (73.8–90.2 V) and dynamic impedance, which causes uneven current sharing and potential thermal runaway. For higher surge capacity, select a single higher-rated device (e.g., 1.5KE100C) or implement staged protection with upstream MOVs and downstream low-capacitance TVS arrays instead of paralleling P6KE82C units.
