Product details
Overview
P4KE22CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 20.9 V minimum breakdown voltage (VBR), 18.8 V maximum standoff voltage (VWM), 30.6 V clamping voltage at 13.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the P4KE22CHE3/54 datasheet, P4KE22CHE3/54 pinout, P4KE22CHE3/54 application, or P4KE22CHE3/54 equivalent, key selection criteria include verified AEC-Q101 qualification, DO-41 mechanical compatibility, bidirectional-capable variant availability (P4KE22CHE3/54 is unidirectional), and thermal resistance (RθJL = 66 °C/W) for board-level surge margining.
Technical Context
This TVS diode operates as a silicon avalanche device with glass-passivated junction, delivering sub-nanosecond response to ESD and inductive switching transients. Its unidirectional polarity uses cathode-band marking and exhibits 1.0 mA test current (IT) for VBR measurement, with forward voltage limited to 3.5 V at 25 A per JESD22-B102 solderability spec.
Thermal performance is defined by RθJL = 66 °C/W and RθJA = 100 °C/W (LLead = 10 mm), enabling operation up to +175 °C junction temperature. The device meets UL 94 V-0 flammability and JESD201 Class 2 whisker resistance (HE3 suffix), confirming suitability for automotive-grade reflow and long-term reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 20.9 V - ensures reliable avalanche conduction onset above normal operating voltage of 18.8 V systems |
| VWM | 18.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 30.6 V - clamped voltage during 13.1 A 10/1000 μs transient, limiting downstream IC stress |
| PPPM | 400 W - peak pulse power handling capability under standardized surge waveform |
| IFSM | 40 A - non-repetitive forward surge current rating (8.3 ms half-sine), supporting inrush immunity |
| TJ max | +175 °C - extended junction temperature range enables under-hood automotive use |
| RθJL | 66 °C/W - low junction-to-lead thermal resistance supports PCB copper pour heat sinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A | DO-214AA package; 22 V VWM; 35.5 V VC @ 11.3 A; 600 W PPPM | Higher power rating but larger footprint; requires PCB layout change | Select SMBJ22A when higher surge margin (>400 W) and surface-mount assembly are required. |
| P4KE22A-E3/54 | Same DO-41 package and electrical specs, but commercial-grade (non-AEC-Q101) | Lacks automotive qualification; unsuitable for under-hood or safety-critical functions | Choose P4KE22A-E3/54 only for cost-sensitive consumer or industrial applications where AEC-Q101 is not mandated. |
Compared with SMBJ22A and P4KE22A-E3/54, the P4KE22CHE3/54 uniquely combines AEC-Q101 qualification, DO-41 through-hole compatibility, and validated 175 °C operation - making it the sole option for legacy automotive designs requiring leaded components with full automotive reliability assurance.

FAQ
What is the clamping voltage of the P4KE22CHE3/54 under standard surge conditions?
The P4KE22CHE3/54 clamps to a maximum of 30.6 V at its rated peak pulse current of 13.1 A, measured with a 10/1000 μs waveform. This value is guaranteed per Vishay Document Number 88365 and defines the upper voltage limit imposed on protected circuitry during transient events. The P4KE22CHE3/54 maintains this clamping performance across its full operating temperature range up to +175 °C.
Is the P4KE22CHE3/54 suitable for automotive applications?
Yes, the P4KE22CHE3/54 is AEC-Q101 qualified (confirmed by HE3 suffix and datasheet note on page 3), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its DO-41 package, 175 °C junction rating, and JESD201 Class 2 whisker resistance meet stringent automotive reliability requirements - unlike the commercial-grade P4KE22A-E3/54 variant.
How does the P4KE22CHE3/54 differ from the P4KE22A-E3/54?
The P4KE22CHE3/54 and P4KE22A-E3/54 share identical electrical parameters and DO-41 packaging, but differ in qualification: P4KE22CHE3/54 carries AEC-Q101 certification and JESD201 Class 2 whisker resistance, while P4KE22A-E3/54 is commercial grade only. This makes the P4KE22CHE3/54 appropriate for automotive and high-reliability industrial use, whereas the P4KE22A-E3/54 is limited to non-automotive applications.
What is the standoff voltage rating for the P4KE22CHE3/54?
The P4KE22CHE3/54 has a maximum standoff voltage (VWM) of 18.8 V, meaning it remains non-conductive with leakage current ≤1.0 μA up to this reverse voltage. This allows safe integration into 15–18 V nominal systems such as automotive 12 V circuits or industrial 24 V rails, ensuring no interference with normal operation while providing immediate clamping above threshold.
Does the P4KE22CHE3/54 have bidirectional capability?
No, the P4KE22CHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants in the same family use the "CA" suffix (e.g., P4KE22CA). For applications requiring symmetrical clamping on AC lines or differential signals, a separate bidirectional part must be selected - the P4KE22CHE3/54 only clamps in reverse bias and conducts forward like a standard diode.
