Product details
Overview
P4KE22A-E3/54 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 20.9 V minimum / 23.1 V maximum breakdown voltage at 1.0 mA test current, 18.8 V stand-off voltage, 1.0 μA max reverse leakage at VWM, 13.1 A peak pulse current (10/1000 μs), and 30.6 V clamping voltage at IPPM - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the P4KE22A-E3/54 datasheet, P4KE22A-E3/54 pinout, P4KE22A-E3/54 application, or P4KE22A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, standoff voltage compatibility with nominal line voltage, thermal derating above 25 °C, and AEC-Q101 qualification status for automotive use.
Technical Context
This unidirectional TVS operates as a voltage-clamping device triggered by transient overvoltage events exceeding its breakdown threshold. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under 400 W peak pulse power (10/1000 μs waveform, 0.01 % duty cycle).
Designed for single-polarity protection, it exhibits forward conduction only when anode-to-cathode polarity is applied; the cathode is marked by a color band. Thermal performance is defined by RθJL = 66 °C/W and RθJA = 100 °C/W, with maximum junction temperature of +175 °C and operating range from –55 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 20.9 V min / 23.1 V max at 1.0 mA - defines precise overvoltage trigger point for reliable clamping onset |
| Stand-off Voltage VWM | 18.8 V - maximum continuous working voltage before leakage exceeds 1.0 μA; must exceed system nominal voltage |
| Clamping Voltage VC | 30.6 V at 13.1 A IPPM - peak voltage seen by protected circuit during worst-case transient; determines safe margin for downstream ICs |
| Peak Pulse Power PPPM | 400 W (10/1000 μs) - energy-handling capability for common lightning/surge waveforms per IEC 61000-4-5 |

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 nominal VBR; same 400 W PPPM but lower RθJA (50 °C/W) and higher IPPM (18.9 A) | Better thermal performance in PCB-constrained layouts; requires larger footprint than DO-41 | Select SMBJ22A when board space allows improved thermal dissipation and higher surge current handling is needed |
| 1.5KE22A | Same DO-41 package; 22 V nominal VBR; 1500 W PPPM (10/1000 μs); higher clamping voltage (35.5 V) | Higher energy rating suits infrequent, high-energy transients (e.g., AC mains surges); less suitable for fast, repetitive noise | Choose 1.5KE22A only where 1500 W capability is required and 35.5 V clamping is acceptable for protected circuitry |
Compared with SMBJ22A and 1.5KE22A, P4KE22A-E3/54 offers optimal balance of compact DO-41 form factor, AEC-Q101 qualification, and precise 30.6 V clamping - making it preferred for space-constrained automotive and industrial modules requiring certified reliability.

FAQ
What is the breakdown voltage tolerance of P4KE22A-E3/54?
The P4KE22A-E3/54 has a specified breakdown voltage range of 20.9 V minimum to 23.1 V maximum at 1.0 mA test current, representing a ±5 % tolerance around the nominal 22 V rating. This tight VBR window ensures consistent clamping onset across production lots and supports predictable circuit protection design for P4KE22A-E3/54 implementations.
Is P4KE22A-E3/54 suitable for bidirectional transient protection?
No, P4KE22A-E3/54 is a unidirectional TVS diode - it clamps only when reverse-biased beyond its breakdown voltage and conducts forward current like a standard diode. For bidirectional protection, Vishay offers the P4KE22CA variant; using P4KE22A-E3/54 in AC-coupled or symmetrical signal lines would require external circuitry to ensure correct polarity alignment.
Does P4KE22A-E3/54 meet automotive qualification standards?
Yes, P4KE22A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control, body electronics, and ADAS sensor interfaces. The E3 suffix denotes RoHS compliance and JESD 201 class 1A whisker testing, further validating reliability for automotive-grade production use of P4KE22A-E3/54.
What is the maximum clamping voltage for P4KE22A-E3/54 under surge conditions?
The maximum clamping voltage (VC) for P4KE22A-E3/54 is 30.6 V at its rated peak pulse current of 13.1 A (10/1000 μs waveform). This value defines the highest voltage imposed on the protected circuit during worst-case transient events and must be verified against the absolute maximum ratings of downstream ICs in any P4KE22A-E3/54 design.
How does the thermal resistance of P4KE22A-E3/54 affect its surge handling capability?
P4KE22A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient (RθJA) of 100 °C/W. At elevated ambient temperatures, its peak pulse power must be derated per Figure 2 in the datasheet; for example, at TA = 85 °C, usable PPPM drops to ~260 W - critical for sustained surge duty in P4KE22A-E3/54 deployments.
