Product details
Overview
P6KE8.2HE3/73 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 a 6.45 V minimum breakdown voltage (VBR), 7.02 V maximum stand-off voltage (VWM), 12.1 V clamping voltage (VC) at 49.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used in automotive ECU input protection and industrial sensor interface circuits.
For engineers reviewing the P6KE8.2HE3/73 datasheet, P6KE8.2HE3/73 pinout, P6KE8.2HE3/73 application, or P6KE8.2HE3/73 equivalent, key selection criteria include clamping performance under 50 A surge, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, and RoHS-compliant matte tin-plated leads per J-STD-002.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (7.02 V), it avalanches into low-impedance conduction to divert surge current away from downstream ICs. Its glass-passivated junction enables fast response (<1 ns) and stable breakdown characteristics across temperature.
The device is rated for 100 A non-repetitive forward surge current (IFSM) and exhibits 0.065 %/°C temperature coefficient of VBR, ensuring predictable clamping behavior from –55 °C to +175 °C operating junction range. Thermal design relies on lead-to-case conduction (RθJL = 20 °C/W), not PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.02 V maximum - defines highest continuous DC or RMS voltage the device blocks without significant leakage |
| VBR @ IT = 10 mA | 7.79–8.61 V - ensures reliable avalanche initiation before system damage occurs during transients |
| VC @ IPPM = 49.6 A | 12.1 V - maximum voltage seen by protected circuit during worst-case 600 W surge event |
| PPPM | 600 W - peak power handling capability with 10/1000 μs waveform, supporting IEC 61000-4-5 Level 4 compliance |
| IFSM | 100 A - withstands 8.3 ms half-sine surge without failure, critical for relay coil or motor switch-off spikes |
| TJ max. | +175 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures |
| RθJL | 20 °C/W - quantifies thermal path efficiency from junction to lead; dictates minimum lead length for thermal derating |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0. Cathode indicated by color band on one end; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Low-side reference node | Connected to ground or lowest potential rail; completes shunt path during avalanche conduction |

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage (<1000 μA at VWM) over 15+ year service life |
| 600 W peak pulse power | Supports robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 4 kV surge events |
| Matte tin plated leads | Guarantees solderability per J-STD-002 and whisker resistance per JESD 201 Class 2 (HE3 suffix) |
| Low clamping ratio (VC/VBR ≈ 1.5) | Minimizes stress on downstream 5 V logic devices during transient suppression |

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; same 600 W rating but lower RθJA (50 °C/W vs. 75 °C/W) | Better suited for surface-mount layouts with limited board space; lacks AEC-Q101 qualification | Select SMBJ8.0A only if SMT assembly is required and automotive qualification is not mandatory. |
| P6KE8.2A-E3/54 | Same die and electrical specs; differs only in packaging - tape-and-reel (54) vs. bulk (73); both HE3 suffix indicates AEC-Q101 and Class 2 whisker test | No functional difference; identical performance in circuit; choice depends solely on procurement logistics | Choose P6KE8.2A-E3/54 for automated pick-and-place; P6KE8.2HE3/73 for manual or low-volume prototyping. |
Compared with SMBJ8.0A, P6KE8.2HE3/73 offers automotive-grade reliability and through-hole mechanical robustness but requires more PCB real estate; versus P6KE8.2A-E3/54, it delivers identical protection performance with optimized packaging for small-batch builds.

FAQ
What is the maximum clamping voltage of the P6KE8.2HE3/73 under surge conditions?
The P6KE8.2HE3/73 clamps to a maximum of 12.1 V when subjected to its rated peak pulse current of 49.6 A (10/1000 μs waveform). This value is measured per JEDEC standards and guarantees that downstream 5 V logic components remain within safe operating voltage limits during transient events. The P6KE8.2HE3/73 achieves this with minimal voltage overshoot due to its low incremental surge resistance and glass-passivated junction.
Is the P6KE8.2HE3/73 qualified for automotive applications?
Yes, the P6KE8.2HE3/73 carries the HE3 suffix, which denotes full AEC-Q101 qualification per Vishay's documentation (Document Number: 88369, Revision: 18-Sep-12). This includes stress testing for temperature cycling, humidity bias, and high-temperature operating life - confirming suitability for under-hood and chassis-mounted automotive electronics. The P6KE8.2HE3/73 is explicitly listed in the AEC-Q101 qualified devices table in the datasheet.
How does the P6KE8.2HE3/73 differ from the P6KE8.2A-E3/54?
The P6KE8.2HE3/73 and P6KE8.2A-E3/54 share identical electrical specifications, thermal characteristics, and AEC-Q101 qualification. Their only difference lies in packaging format: P6KE8.2HE3/73 is supplied in bulk (73), while P6KE8.2A-E3/54 uses 13" paper tape-and-reel (54). Both carry the HE3 suffix, confirming RoHS compliance and JESD 201 Class 2 whisker resistance. The P6KE8.2HE3/73 is optimized for manual or low-volume assembly workflows.
What is the standoff voltage rating of the P6KE8.2HE3/73?
The P6KE8.2HE3/73 has a maximum stand-off voltage (VWM) of 7.02 V, meaning it remains in high-impedance blocking mode for any continuous DC or RMS voltage up to this level. This allows safe integration into 5 V systems with margin for ripple and tolerance stack-up. Leakage current stays below 1000 μA at VWM, ensuring negligible power loss in standby operation. The P6KE8.2HE3/73 maintains this rating across its full operating temperature range (–55 °C to +175 °C).
Can the P6KE8.2HE3/73 be used in bi-directional protection circuits?
No - the P6KE8.2HE3/73 is a uni-directional TVS diode, identifiable by its cathode band marking and specified VBR/VWM values only for reverse bias. For bi-directional applications (e.g., AC lines or differential data buses), Vishay specifies CA-suffix variants like P6KE8.2CA. Using the P6KE8.2HE3/73 in forward-biased configurations risks permanent conduction and failure; always verify polarity alignment in schematic capture and layout for the P6KE8.2HE3/73.
