Product details
Overview
P6KE82HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 77.9 V minimum breakdown voltage (VBR), 70.1 V maximum stand-off voltage (VWM), 113 V clamping voltage (VC) at 5.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive engine control units, industrial PLC I/O modules, and telecom power supply inputs.
For engineers reviewing the P6KE82HE3/54 datasheet, P6KE82HE3/54 pinout, P6KE82HE3/54 application, or P6KE82HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, 175 °C max junction temperature, and verified clamping performance under repetitive 0.01% duty cycle surges - critical for robust ESD and load-dump protection design.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VWM (70.1 V), it transitions from high-impedance blocking to low-impedance conduction at VBR (77.9–86.1 V), limiting transient energy via controlled avalanche breakdown. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and repeatable clamping behavior across temperature.
Designed for unidirectional DC line protection, P6KE82HE3/54 delivers 113 V clamping at 5.3 A IPPM (10/1000 µs), with thermal resistance RθJL = 20 °C/W enabling effective lead-based heat dissipation. It meets JESD22-B106 solderability (275 °C, 10 s) and JESD201 Class 2 whisker resistance - confirming suitability for automotive-grade reflow and long-term reliability.

IC Role / Device Role / Timing Role: Primary front-end protection element mounted adjacent to screw-terminal block, absorbing energy before optocoupler or Schmitt trigger input stage. Use Value: Maintains signal integrity by holding clamp voltage below 113 V while sustaining <1 µA leakage at 24 V - avoiding false triggering or input loading errors. |
| Telecom Power Supply DC Output | Consumer Appliance Motor Drive Board |
|
Use Scenario: Safeguards +48 V DC output of telecom rectifier modules against lightning-induced surges on distribution bus lines. IC Role / Device Role / Timing Role: Secondary-stage TVS located after bulk filter capacitors and before hot-swap controllers or backplane connectors. Use Value: Delivers 600 W surge capacity with 113 V clamping, ensuring compliance with ITU-T K.20/21 secondary protection requirements without compromising hold-up time. |
Use Scenario: Guards microcontroller GPIO and gate driver supply lines on washing machine motor control boards exposed to brush-commutator noise and pump startup spikes. IC Role / Device Role / Timing Role: Localized protection device placed near MCU VDD pins and half-bridge driver VBS supplies to suppress fast-rising (<1 ns) commutation transients. Use Value: Fast response time and low dynamic impedance limit overshoot to <113 V, preventing reset corruption or MOSFET shoot-through due to supply rail disturbance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; 8.0 V VWM, 12.3 V VC @ 43.3 A; same 600 W rating but higher IPPM and lower clamping ratio | Surface-mount alternative for space-constrained PCBs; requires rework of footprint and thermal relief design | Select when board real estate is limited and SMT assembly is preferred; verify thermal pad layout for RθJA = 40 °C/W |
| 1.5KE82A | Same DO-204AC package; identical VWM/VBR/VC specs but not AEC-Q101 qualified; commercial-grade only | Acceptable for non-automotive industrial use where qualification is not mandated; lower cost but no automotive traceability | Choose for cost-sensitive consumer or white-goods applications where AEC-Q101 is unnecessary; avoid in automotive BOMs |
Compared with SMBJ8.0A and 1.5KE82A, P6KE82HE3/54 uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, and verified 175 °C operation - making it the only option qualified for under-hood automotive deployment without footprint or reliability compromise.

FAQ
What is the maximum clamping voltage of the P6KE82HE3/54 under standard test conditions?
The P6KE82HE3/54 has a maximum clamping voltage (VC) of 113 V when subjected to a 10/1000 µs waveform peak pulse current (IPPM) of 5.3 A. This value is measured per JEDEC standards and reflects worst-case voltage seen by downstream circuitry during surge events - critical for ensuring protected ICs remain within their absolute maximum ratings. The P6KE82HE3/54 maintains this clamping performance across its full operating temperature range (-55 °C to +175 °C).
Is the P6KE82HE3/54 suitable for automotive applications?
Yes, the P6KE82HE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units and body electronics. Its construction - glass-passivated junction, matte tin-plated leads meeting JESD 201 Class 2, and 175 °C maximum junction temperature - satisfies stress test requirements for temperature cycling, high-temperature operating life, and mechanical shock. The P6KE82HE3/54 appears in Vishay's official AEC-Q101 certified product list with full test report traceability.
What does the 'HE3/54' suffix indicate in P6KE82HE3/54?
The 'HE3' suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; '54' specifies the preferred packaging code for 13-inch paper tape and reel with 4000 units per reel. This distinguishes P6KE82HE3/54 from commercial-grade variants like P6KE82A-E3/54 (non-AEC-Q101) and confirms full automotive process control and material compliance - essential for Tier-1 supplier documentation and PPAP submission. The P6KE82HE3/54 meets UL 94 V-0 flammability and J-STD-002 solderability standards.
How does the P6KE82HE3/54 compare to the 1.5KE82A in terms of reliability and application scope?
The P6KE82HE3/54 shares identical electrical specifications (VWM, VBR, VC, PPPM) with the 1.5KE82A but adds AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and extended temperature validation. While 1.5KE82A serves commercial/industrial uses, the P6KE82HE3/54 is approved for automotive under-hood deployment. Both use DO-204AC packages, but only the P6KE82HE3/54 guarantees traceable lot-level qualification data required for automotive BOMs - making the P6KE82HE3/54 mandatory where functional safety or OEM compliance applies.
Can the P6KE82HE3/54 be used in bi-directional protection configurations?
No, the P6KE82HE3/54 is strictly a uni-directional TVS diode, as confirmed by its part number suffix 'A' (not 'CA') and specification table entries listing only VBR and VWM for single-polarity operation. Bi-directional variants such as P6KE82CA exist in the same family but feature symmetric breakdown in both directions and no polarity marking. Using P6KE82HE3/54 in AC or floating-line applications would result in forward conduction during negative half-cycles - potentially damaging the device or failing to protect. Always select P6KE82CA for bi-directional needs.
