Product details
Overview
P6KE82CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features a 70.1 V stand-off voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA, 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE82CHE3/54 datasheet, P6KE82CHE3/54 pinout, P6KE82CHE3/54 application, or P6KE82CHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, bi-directional polarity, 175 °C max junction temperature, low incremental surge resistance, and UL 94 V-0 molded epoxy case - critical for reliability in harsh-environment transient suppression.
Technical Context
The P6KE82CHE3/54 operates as a voltage-clamping device that enters avalanche conduction when reverse (or forward, in bi-directional mode) voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and fast response time (<1 ns), enabling protection against ESD, lightning-induced surges, and inductive switching spikes.
It delivers 600 W peak pulse power under standardized 10/1000 μs waveform conditions with 0.01 % duty cycle, and exhibits 20 °C/W typical junction-to-lead thermal resistance - supporting robust thermal performance in compact PCB layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 70.1 V - Maximum continuous operating voltage before clamping begins; defines safe working margin below breakdown. |
| VBR (Breakdown Voltage) | 77.9–86.1 V at 1 mA - Tight tolerance ensures predictable turn-on across production lots and temperature range. |
| VC (Clamping Voltage) | 113 V at 5.3 A IPPM - Limits downstream voltage stress during surge events; enables compatibility with 100 V-rated components. |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients per JEDEC-standard 10/1000 μs waveform without degradation. |
| IPPM (Peak Pulse Current) | 5.3 A - Peak surge current capability directly determines protection level against defined threat waveforms. |
| TJmax | 175 °C - Enables operation in under-hood automotive or high-ambient industrial environments. |
| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102; no polarity marking (bi-directional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (reversible) | Bi-directional avalanche junction | Either lead serves as anode or cathode depending on transient polarity; symmetrical clamping in both directions. |
| Lead 1 / Lead 2 | Current path terminals | Leads conduct surge current bidirectionally; low thermal resistance (20 °C/W) enables efficient heat transfer to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR and long-term reliability under thermal cycling and humidity exposure. |
| 600 W peak pulse power (10/1000 μs) | Provides industry-standard surge immunity for IEC 61000-4-5 Level 3 (1 kV/2 kV) and ISO 7637-2 pulse 1/2/5a. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body electronics, and ADAS modules requiring zero-failure field performance. |
| UL 94 V-0 molding compound | Prevents flame propagation in safety-critical applications such as EV battery management and charging interfaces. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected devices compared to higher-ratio TVS devices. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting LIN bus transceivers and microcontrollers from load dump and alternator ripple in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed between power rail and ground, responding within <1 ns to suppress transients exceeding 70 V. Use Value: Prevents latch-up or permanent damage to 5 V/3.3 V logic ICs while maintaining system uptime under repeated 100 V/50 ms load dump events. |
Use Scenario: Shielding analog outputs of pressure/temperature sensors in factory automation PLC I/O modules from motor drive noise. IC Role / Device Role / Timing Role: Low-capacitance (≈50 pF) shunt protector on 0–10 V or 4–20 mA signal lines, clamping induced spikes before they reach ADC inputs. Use Value: Maintains measurement accuracy by limiting transient-induced offset errors and eliminating false triggers in closed-loop control systems. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feed Protection |
|
Use Scenario: Safeguarding primary-side controllers and bridge rectifiers in AC/DC adapters against line surges and EFT bursts. IC Role / Device Role / Timing Role: Stand-off rated at 70.1 V, placed across bulk capacitor input to absorb 600 W surges without failure. Use Value: Extends adapter lifetime in regions with unstable grid voltage and eliminates need for redundant MOV+gas discharge tube staging. |
Use Scenario: Protecting PoE-powered equipment (e.g., IP cameras, wireless APs) from induced surges on 48 V DC feed lines. IC Role / Device Role / Timing Role: Bi-directional TVS mounted at PD (Powered Device) input, clamping common-mode transients up to ±113 V relative to ground. Use Value: Ensures uninterrupted operation during lightning-induced surges on outdoor Ethernet runs while complying with IEEE 802.3af/at immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ70CA | DO-214AA package; lower 70 V VWM, same 113 V VC; 600 W rating but higher capacitance (~100 pF). | Better suited for board space-constrained designs; less optimal for high-frequency signal lines due to higher junction capacitance. | Select SMBJ70CA when footprint reduction is prioritized over signal integrity on fast analog or data lines. |
| 1.5KE82CA | Same DO-204AC package; identical VWM/VBR/VC specs; higher 1500 W PPPM rating but larger physical size and higher leakage. | Used where higher single-event surge margin is required (e.g., outdoor telecom cabinets), but not AEC-Q101 qualified. | Choose 1.5KE82CA only if 1500 W surge headroom is mandatory and automotive qualification is not required. |
Compared with SMBJ70CA and 1.5KE82CA, the P6KE82CHE3/54 uniquely balances AEC-Q101 compliance, DO-15 form factor, and precise 70.1 V stand-off - making it the preferred choice for cost-sensitive, space-limited automotive and industrial designs requiring validated reliability.

FAQ
What does the "HE3" suffix indicate in P6KE82CHE3/54?
The "HE3" suffix in P6KE82CHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. This distinguishes it from the commercial-grade "E3" variant and confirms suitability for automotive applications requiring extended reliability validation under thermal and mechanical stress.
Is P6KE82CHE3/54 unidirectional or bidirectional?
P6KE82CHE3/54 is a bi-directional TVS diode, as confirmed by the "CA" designation in its full part number (P6KE82C) and absence of polarity marking on the DO-204AC package. It provides symmetrical clamping for both positive and negative transients, making it ideal for AC-coupled or floating signal lines.
What is the maximum clamping voltage of P6KE82CHE3/54 at rated surge current?
The maximum clamping voltage (VC) of P6KE82CHE3/54 is 113 V at 5.3 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can P6KE82CHE3/54 replace P6KE82A in a design?
No - P6KE82CHE3/54 is bi-directional (P6KE82C), while P6KE82A is unidirectional. Their VBR ranges differ slightly (77.9–86.1 V vs. 77.9–86.1 V), but polarity mismatch makes direct substitution unsafe unless the circuit explicitly requires bi-directional clamping and has no DC bias constraints.
What is the thermal resistance specification for P6KE82CHE3/54?
P6KE82CHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard test conditions. This parameter supports thermal design calculations for PCB copper pour sizing and ensures reliable operation at 175 °C maximum junction temperature without external heatsinking.
