Product details
Overview
P6KE8.2CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 600 W peak pulse power (10/1000 μs), 7.79–8.61 V breakdown voltage at 10 mA, 7.02 V stand-off voltage, 12.1 V maximum clamping voltage at 49.6 A peak pulse current, and AEC-Q101 qualification - deployed in automotive sensor interface protection.
For engineers reviewing the P6KE8.2CHE3/73 datasheet, P6KE8.2CHE3/73 pinout, P6KE8.2CHE3/73 application, or P6KE8.2CHE3/73 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, thermal resistance (20 °C/W junction-to-lead), unidirectional polarity marking, RoHS-compliant matte tin plating, and 175 °C max junction temperature capability.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 7.02 V), but avalanches rapidly (<1 ns response) when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR and low leakage (≤200 μA at VWM), while the DO-204AC package enables surface-mount or through-hole mounting with 0.375" lead length for thermal management.
The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine), dissipates 5.0 W on infinite heatsink at TL = 75 °C, and exhibits +0.065 %/°C temperature coefficient of VBR - critical for stability across automotive ambient ranges (-40 to +125 °C board temp).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 7.79 V / 8.61 V at 10 mA - defines precise avalanche initiation window for reliable triggering without false trips |
| VWM | 7.02 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 12.1 V at 49.6 A - clamping voltage limiting stress on downstream ICs during 10/1000 μs transients |
| PPPM | 600 W - peak surge energy handling capacity per single transient event |
| RθJL | 20 °C/W - enables direct PCB copper pour heat sinking to maintain <175 °C junction temp under repeated surges |
| TJ max | 175 °C - supports operation in under-hood automotive environments with minimal derating |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TC, and ESD testing per JESD47 |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during positive transients when cathode is biased higher |
| Cathode | Avalanche clamping terminal | Marked end; connected to protected line (e.g., 5 V rail); clamps voltage to ≤12.1 V when transient exceeds 7.79 V |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance (±5 %) and low leakage (<200 μA) over 10-year field life |
| 600 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 1/2a/5a surges without degradation in automotive ECUs |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity bias, and mechanical shock |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., load dump edge rates >100 V/μs) |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance - suitable for high-reliability industrial control systems |
Applications
| Automotive Sensor Interface | Industrial PLC 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 |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; 8.0 V VWM, 12.0 V VC @ 49.2 A; 600 W rating; same AEC-Q101 qualification | Surface-mount only; requires PCB rework for replacement; lower thermal resistance (RθJA = 40 °C/W vs. 75 °C/W) | Select SMBJ8.0A for space-constrained SMT designs where leaded DO-15 layout is unavailable. |
| 1.5KE8.2A | Same DO-204AC package; identical VBR/VWM/VC; 1500 W PPPM; no AEC-Q101 qualification; commercial grade only | Higher surge capacity but lacks automotive reliability validation; not suitable for safety-critical vehicle systems | Choose 1.5KE8.2A only for cost-sensitive industrial equipment where AEC-Q101 is not mandated. |
Compared with SMBJ8.0A and 1.5KE8.2A, the P6KE8.2CHE3/73 uniquely balances AEC-Q101 compliance, through-hole manufacturability, and precise 7.02 V stand-off for 5 V system protection - making it optimal for automotive Tier-1 module assembly and legacy through-hole production lines.

FAQ
What is the maximum clamping voltage of the P6KE8.2CHE3/73 under standard test conditions?
The P6KE8.2CHE3/73 has a maximum clamping voltage (VC) of 12.1 V at 49.6 A peak pulse current using the 10/1000 μs waveform. This value is measured per JEDEC standards and represents the upper voltage limit imposed on protected circuitry during worst-case transient events - critical for ensuring compatibility with 5 V logic interfaces and automotive microcontrollers.
Is the P6KE8.2CHE3/73 suitable for automotive applications?
Yes, the P6KE8.2CHE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junction, matte tin-plated leads meeting JESD 22-B102, and operation up to 175 °C junction temperature - fulfilling requirements for engine control units, body electronics, and ADAS sensor modules per ISO 16750-2.
How does the HE3 suffix affect the P6KE8.2CHE3/73 specification?
HE3 denotes RoHS-compliant, AEC-Q101-qualified version with JESD 201 Class 2 whisker resistance. Unlike base E3 variants, HE3 guarantees automotive-grade reliability and enhanced lead finish durability - essential for high-vibration environments and extended thermal cycling in vehicle platforms.
What is the stand-off voltage (VWM) of the P6KE8.2CHE3/73, and why does it matter?
The P6KE8.2CHE3/73 has a stand-off voltage (VWM) of 7.02 V, meaning it remains non-conductive up to this DC or RMS voltage level. This parameter ensures no leakage-induced power loss or false triggering in 5 V systems, while providing sufficient margin below the 7.79 V minimum breakdown voltage to prevent premature conduction during normal operation.
Can the P6KE8.2CHE3/73 be used in bi-directional protection circuits?
No, the P6KE8.2CHE3/73 is a uni-directional TVS diode, identified by the "A" suffix and cathode band marking. For bi-directional applications (e.g., AC lines or differential data buses), Vishay specifies CA-suffixed variants like P6KE8.2CA - which have symmetric breakdown in both polarities and no polarity marking.
