Product details
Overview
P6KE220HE3/73 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 209 V minimum breakdown voltage (VBR), 185 V maximum stand-off voltage (VWM), 328 V clamping voltage (VC) at 1.8 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE220HE3/73 datasheet, P6KE220HE3/73 pinout, P6KE220HE3/73 application, or P6KE220HE3/73 equivalent, this device is selected for robust ESD and surge protection in automotive ECUs, industrial sensor interfaces, and telecom power supplies where stable clamping performance under repetitive transients is required.
Technical Context
The P6KE220HE3/73 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to transient events and low incremental surge resistance. Its uni-directional polarity enables integration into DC-biased circuits without reverse conduction during normal operation.
It is rated for 175 °C maximum junction temperature, exhibits 0.108 %/°C temperature coefficient of VBR, and maintains 1.0 µA maximum reverse leakage at VWM. The device complies with UL 497B recognition (QVGQ2) and meets JESD 22-B102 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220AHE3/A | Lower peak pulse power (400 W), SMA package (surface-mount), same VWM/VBR range | Better suited for space-constrained PCBs; less thermal mass than DO-15 for high-frequency transients | Select when board area is limited and 400 W surge margin suffices |
| 1.5KE220A | Same DO-204AC package, 1500 W peak power, higher VC (355 V), no AEC-Q101 qualification | Higher energy handling for non-automotive industrial use; lacks automotive reliability validation | Select when higher single-pulse energy tolerance is needed and automotive qualification is not required |
Compared with P6KE220HE3/73, SMAJ220AHE3/A offers compact SMT integration but reduced surge capacity, while 1.5KE220A delivers greater pulse energy handling at the cost of automotive qualification and tighter clamping performance.

FAQ
What is the maximum clamping voltage of the P6KE220HE3/73 under standard test conditions?
The P6KE220HE3/73 has a maximum clamping voltage (VC) of 328 V when subjected to its rated peak pulse current of 1.8 A using the 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on the protected circuit during transient events. The P6KE220HE3/73 maintains this clamping performance across its qualified temperature range and after AEC-Q101 stress testing.
Is the P6KE220HE3/73 suitable for automotive applications?
Yes, the P6KE220HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, glass-passivated junction, and UL 497B recognition make it appropriate for protecting power inputs in engine control units, body control modules, and ADAS sensor power supplies. The HE3 suffix confirms AEC-Q101 compliance per the Vishay ordering nomenclature.
How does the P6KE220HE3/73 differ from the P6KE220A-E3/73 variant?
The P6KE220HE3/73 is AEC-Q101 qualified (HE3 suffix), whereas the P6KE220A-E3/73 is commercial-grade only (E3 suffix). Both share identical electrical parameters (VBR, VWM, VC, PPPM) and DO-204AC packaging, but only the HE3 version undergoes automotive-specific stress testing including temperature cycling, high-temperature operating life, and ESD verification. The P6KE220HE3/73 is the correct choice for automotive production designs.
What is the reverse leakage current specification for the P6KE220HE3/73 at its maximum working voltage?
At its maximum stand-off voltage (VWM) of 185 V and ambient temperature of 25 °C, the P6KE220HE3/73 exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal impact on system power budget and signal integrity in high-impedance sensing or bias networks. Leakage remains within specification up to 175 °C junction temperature per thermal derating curves.
Can the P6KE220HE3/73 be used in bi-directional protection configurations?
No, the P6KE220HE3/73 is a uni-directional TVS diode, indicated by the "A" suffix and presence of a cathode band. For bi-directional applications, Vishay specifies the "CA" suffix (e.g., P6KE220CA). Using the P6KE220HE3/73 in reverse-biased configurations risks permanent failure due to lack of symmetric avalanche capability. Always match device polarity to circuit topology-P6KE220HE3/73 is intended for DC-biased lines with defined ground reference.
