Product details
Overview
P6KE22HE3/54 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 sensitive electronics. It features a 20.9 V minimum breakdown voltage (VBR), 30.6 V maximum clamping voltage (VC) at 19.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and I/O lines in automotive ECUs and industrial motor controllers.
For engineers reviewing the P6KE22HE3/54 datasheet, P6KE22HE3/54 pinout, P6KE22HE3/54 application, or P6KE22HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), junction temperature range (–55 to +175 °C), and precise clamping behavior under transient stress - critical for surge immunity validation in ISO 7637-2 compliant designs.
Technical Context
The P6KE22HE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to ESD and lightning-induced transients. Its uni-directional polarity uses a cathode band marking and exhibits 18.8 V stand-off voltage (VWM) with ≤1.0 μA reverse leakage at that voltage.
It is rated for 100 A non-repetitive forward surge current (IFSM) at 8.3 ms half-sine, dissipates 5.0 W on infinite heatsink at TL = 75 °C, and maintains stable clamping performance across –55 °C to +175 °C operating junction temperature - validated per AEC-Q101 stress test conditions including HTGB, HTRB, and temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V at 1.0 mA test current - defines reliable avalanche initiation threshold under DC bias |
| VWM | 18.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 30.6 V at 19.6 A (10/1000 μs) - peak clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - surge energy handling capacity without degradation, enabling single-device protection against IEC 61000-4-5 Level 3 (1 kV/2 Ω) |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports sustained surge duty cycles without thermal runaway |
| TJ max. | +175 °C - extended junction temperature rating allows use in under-hood automotive environments |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including high-temperature reverse bias and accelerated life testing |

FAQ
What is the clamping voltage of the P6KE22HE3/54 under maximum surge conditions?
The P6KE22HE3/54 has a maximum clamping voltage (VC) of 30.6 V when subjected to its rated peak pulse current of 19.6 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures protected circuits remain below critical voltage thresholds during transient events. The P6KE22HE3/54 achieves this clamping performance while maintaining low incremental surge resistance and stable thermal behavior up to +175 °C junction temperature.
Is the P6KE22HE3/54 suitable for automotive applications?
Yes, the P6KE22HE3/54 is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its DO-204AC package, glass-passivated junction, and validated performance across –55 °C to +175 °C make it compliant with ISO 7637-2 and IEC 61000-4-5 requirements. The P6KE22HE3/54 also meets JESD 201 Class 2 whisker resistance and RoHS standards required for modern automotive production.
How does the P6KE22HE3/54 differ from the commercial-grade P6KE22A-E3/54?
The P6KE22HE3/54 differs from P6KE22A-E3/54 solely in qualification level: the "H" suffix indicates AEC-Q101 qualification, including additional stress testing (HTGB, HTRB, temperature cycling), while both share identical electrical specs, DO-204AC packaging, and RoHS compliance. The P6KE22HE3/54 is screened to automotive reliability standards, whereas P6KE22A-E3/54 is commercial-grade. Both use the same die and process - only final test screening differs.
What is the maximum reverse leakage current for the P6KE22HE3/54 at its stand-off voltage?
The P6KE22HE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its stand-off voltage (VWM) of 18.8 V, measured at TA = 25 °C. This low leakage ensures minimal power loss and signal interference in always-on circuits such as automotive wake-up lines or sensor bias networks. The P6KE22HE3/54 maintains this specification across its full operating temperature range, supporting reliable long-term operation in battery-critical systems.
Can the P6KE22HE3/54 be used in bi-directional configurations?
No, the P6KE22HE3/54 is a uni-directional TVS diode, indicated by the "A" suffix and cathode band marking. Bi-directional variants use the "CA" suffix (e.g., P6KE22CA). Using the P6KE22HE3/54 in bi-directional applications would result in forward conduction during negative transients, causing failure. For symmetric surge protection, select P6KE22CAHE3/54 - which shares the same AEC-Q101 qualification and DO-204AC package as the P6KE22HE3/54.
