Product details
Overview
P6KE82A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 70.1V reverse standoff voltage (VRWM), 77.9V minimum breakdown voltage (VBR), 113V maximum clamping voltage (VC) at 5.3A peak pulse current, and DO-15 package with glass-passivated junction-used in industrial power supplies and automotive body electronics.
For engineers reviewing the P6KE82A-T datasheet, P6KE82A-T pinout, P6KE82A-T application, or P6KE82A-T equivalent, this page delivers verified electrical parameters, clamping performance under 1.0ms 600W pulses, thermal resistance values (RθJA = 75°C/W), and direct substitution guidance against active alternatives with matching VRWM and IPP ratings.
Technical Context
This unidirectional TVS diode operates as a fast-acting shunt protector, triggering when transient voltage exceeds its 77.9V–86.1V breakdown range (VBR) and clamping to ≤113V at 5.3A (IPP). Its glass-passivated die ensures stable leakage (<5µA @ VRWM) and robust surge handling across -55°C to +175°C.
The device complies with IEC 61000-4-2/4-4/4-5 standards for ESD, EFT, and surge immunity. Its DO-15 package supports 5.0W steady-state dissipation at TL = +75°C with RθJC = 20°C/W, enabling reliable mounting on copper land areas ≥40mm².
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms non-repetitive 10/1000µs waveform; defines maximum transient energy absorption) |
| Reverse Standoff Voltage (VRWM) | 70.1V (maximum continuous DC or RMS voltage before significant leakage; sets operating rail margin) |
| Breakdown Voltage (VBR) | 77.9V min / 86.1V max @ 1.0mA (voltage at which device enters avalanche conduction; determines turn-on threshold) |
| Clamping Voltage (VC) | 113V max @ 5.3A IPP (voltage seen by protected circuit during surge; critical for downstream IC survival) |
| Peak Pulse Current (IPP) | 5.3A (maximum surge current the device can safely divert without degradation) |
| Thermal Resistance (RθJA) | 75°C/W (junction-to-ambient; used to calculate temperature rise under sustained power dissipation) |
| Operating Temperature | -55°C to +175°C (enables use in under-hood automotive and industrial environments) |
Pinout & Package
Package: DO-15 molded plastic case (UL 94V-0 rated), 0.4g weight, with axial leads plated for MIL-STD-202 solderability. Cathode band marking identifies polarity for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during reverse-biased surge | Connected to protected line; conducts avalanche current to ground when VC exceeded |
| Cathode | Reference terminal / polarity indicator | Marked with band; ties to system ground or lower-potential rail to establish clamping reference |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Supports high-energy transients per IEC 61000-4-5 Level 4 (4kV surge) on 12V/24V systems |
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage (<5µA) over lifetime and temperature |
| Fast response time (<1ps) | Clamps surges before sensitive downstream components experience overstress |
| RoHS-compliant lead finish | Enables compliance with environmental regulations without sacrificing solder wetting or reliability |
| DO-15 mechanical robustness | Withstands board-level mechanical stress and thermal cycling in automotive engine compartments |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input 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 |
|---|---|---|---|
| SMBJ80A-T | DO-214AA package; 80V VRWM; 125V VC @ 4.8A; 600W rating | Surface-mount footprint; higher thermal resistance (RθJA = 110°C/W); lower IPP (4.8A vs. 5.3A) | Select for space-constrained PCBs where reflow compatibility outweighs axial-leaded mechanical robustness |
| 1.5KE82A-T | DO-201AD package; identical 70.1V VRWM and 113V VC; 1500W rating; larger thermal mass | Higher surge capacity (1500W vs. 600W); same clamping but longer lead time and higher cost | Choose when legacy designs require higher energy margin or when operating near thermal limits of P6KE82A-T |
Compared with SMBJ80A-T, P6KE82A-T offers superior thermal performance in through-hole mounting and higher IPP; versus 1.5KE82A-T, it provides identical clamping with smaller footprint and lower cost-but reduced single-pulse energy handling.

FAQ
Is P6KE82A-T still in active production?
No-P6KE82A-T is officially obsolete per Diodes Incorporated's DS21502 Rev. 20-4 (August 2024). While Aetrix Electronics maintains limited legacy stock for continuity support, new designs should migrate to active alternatives like SMBJ80A-T or 1.5KE82A-T with documented qualification status.
What is the meaning of the 'A' suffix in P6KE82A-T?
The 'A' suffix denotes unidirectional polarity (cathode-banded), distinguishing it from bidirectional variants marked 'CA'. This confirms the device functions as a single-quadrant shunt clamp-ideal for DC rail protection where polarity is fixed and reverse conduction must be blocked.
Can P6KE82A-T replace P6KE82CA in a circuit?
No-P6KE82A-T is unidirectional; P6KE82CA is bidirectional. Substituting them requires verifying circuit polarity constraints: using P6KE82A-T in AC-coupled or floating signal paths may cause forward conduction failure or no clamping during negative transients.
How does P6KE82A-T perform under repeated surge stress?
Its 600W rating applies to non-repetitive 1.0ms pulses. Derating curves show >75% peak power retention up to +75°C ambient; however, repetitive surges require thermal analysis using RθJA = 75°C/W and duty cycle limits to avoid junction overheating beyond 175°C.
