Product details
Overview
P6KE82CHE3/73 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 70.1 V minimum breakdown voltage (VBR), 77.9–86.1 V breakdown range at 1 mA, 70.1 V stand-off voltage (VWM), 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 - deployed in automotive ECU input protection, industrial sensor interface circuits, and 24 V DC power supply surge suppression.
For engineers reviewing the P6KE82CHE3/73 datasheet, P6KE82CHE3/73 pinout, P6KE82CHE3/73 application, or P6KE82CHE3/73 equivalent, this device delivers AEC-Q101-qualified transient immunity for harsh environments, low incremental surge resistance for precise clamping, glass-passivated junction reliability, and DO-204AC (DO-15) through-hole compatibility with matte tin-plated leads meeting J-STD-002 solderability standards.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, diverting surge current away from downstream ICs. Its unidirectional polarity enables targeted protection of positive-rail circuits without reverse-bias conduction path concerns.
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), supporting 5.0 W steady-state dissipation on infinite heatsink at TL = 75 °C. The device sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 0.105 %/°C temperature coefficient of VBR, ensuring stable clamping across -55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 70.1 V - Maximum continuous reverse working voltage before leakage exceeds 1 μA; sets upper limit for safe DC rail operation. |
| VBR (min/max) | 77.9 V / 86.1 V at 1 mA - Confirmed breakdown threshold range; ensures reliable triggering above nominal system voltage. |
| VC @ IPPM | 113 V at 5.3 A - Clamped voltage during 10/1000 µs surge; defines worst-case stress imposed on protected load. |

| TJ max. | +175 °C - Maximum junction temperature; enables use in under-hood automotive and high-temperature industrial enclosures. |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package with 0.300" lead spacing; compatible with legacy PCB layouts and wave soldering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ70A-E3/52 | DO-214AA package; lower 70 V VWM, same 113 V VC; 600 W rating; surface-mount only. | Requires PCB redesign for SMD layout; better thermal performance in forced-air environments due to lower RθJA. | Select when board space is constrained and reflow assembly is available; not drop-in for through-hole designs. |
| 1.5KE82A | Same DO-204AC package; identical VWM/VBR/VC specs; 1500 W rating; no AEC-Q101 qualification. | Higher surge margin for infrequent extreme events; lacks automotive qualification and JESD 201 Class 2 whisker resistance. | Choose for cost-sensitive industrial applications where AEC-Q101 is not mandated and higher single-pulse headroom is needed. |
Compared with SMBJ70A-E3/52 and 1.5KE82A, P6KE82CHE3/73 uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, and JESD 201 Class 2 whisker resistance - making it the preferred choice for automotive and long-lifecycle industrial deployments requiring proven reliability and legacy assembly support.

FAQ
What is the maximum clamping voltage of the P6KE82CHE3/73 under standard test conditions?
The P6KE82CHE3/73 has a maximum clamping voltage (VC) of 113 V when subjected to its rated peak pulse current (IPPM) of 5.3 A using the 10/1000 µs waveform. This value is measured at the device terminals and represents the upper bound of voltage seen by protected circuitry during a surge event. The clamping performance is guaranteed across the full operating temperature range (-55 °C to +175 °C) and is integral to the device's ability to safeguard downstream components such as microcontrollers and power management ICs in the P6KE82CHE3/73 application circuit.
Is the P6KE82CHE3/73 suitable for automotive applications?
Yes, the P6KE82CHE3/73 is AEC-Q101 qualified and specifically designed for automotive use, including body control modules, infotainment power supplies, and sensor interfaces. Its construction includes glass-passivated junction technology, matte tin-plated leads compliant with J-STD-002, and JESD 201 Class 2 whisker resistance - all validated per automotive reliability standards. The P6KE82CHE3/73 withstands load dump pulses (ISO 7637-2 Pulse 5a), ESD events (IEC 61000-4-2), and repetitive transients typical in 12 V/24 V vehicle electrical systems.
How does the HE3 suffix in P6KE82CHE3/73 differ from the E3 suffix?
The HE3 suffix in P6KE82CHE3/73 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas the E3 suffix indicates RoHS compliance and commercial-grade qualification only. Both meet UL 94 V-0 flammability and J-STD-002 solderability requirements, but P6KE82CHE3/73 adds automotive-grade process controls, extended temperature validation, and enhanced metallurgical stability for long-term deployment in harsh environments - critical for applications where field reliability of the P6KE82CHE3/73 cannot be compromised.
What is the thermal resistance from junction to lead (RθJL) for the P6KE82CHE3/73?
The P6KE82CHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard test conditions with 0.375" (9.5 mm) lead length. This parameter directly impacts steady-state power handling: at 5.0 W dissipation, the junction-to-lead temperature rise is ~100 °C, allowing safe operation up to +175 °C maximum junction temperature when lead temperature is maintained ≤75 °C. Accurate thermal modeling of the P6KE82CHE3/73 requires this value to determine required copper pour area and trace width in PCB layout.
Can the P6KE82CHE3/73 be used in bi-directional protection circuits?
No, the P6KE82CHE3/73 is a uni-directional TVS diode and is not rated for bi-directional operation. Its electrical characteristics - including breakdown voltage, clamping behavior, and leakage current - are specified only for reverse-bias conduction. For bi-directional protection, Vishay offers the P6KE82C variant (e.g., P6KE82CA), which features symmetrical VBR in both polarities and no cathode marking. Using P6KE82CHE3/73 in AC or floating signal paths may result in unintended forward conduction and failure to suppress negative-going transients.
