Product details
Overview
P4KE24AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on DC power rails and signal lines. It features 22.8 V to 25.2 V breakdown voltage (VBR) at 1 mA, 20.5 V stand-off voltage (VWM), 1.0 μA max reverse leakage at VWM, 33.2 V clamping voltage (VC) at 12.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE24AHE3/54 datasheet, P4KE24AHE3/54 pinout, P4KE24AHE3/54 application, or P4KE24AHE3/54 equivalent, key selection criteria include verified AEC-Q101 qualification, DO-41 mechanical compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJL = 66 °C/W) for board-level thermal design validation.
Technical Context
The P4KE24AHE3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to transient overvoltages. Its clamping behavior is defined by a well-controlled breakdown knee and low incremental surge resistance, enabling predictable energy absorption during ESD or inductive switching events.
Rated for -55 °C to +175 °C junction temperature range and qualified per AEC-Q101, it supports automotive-grade reliability in under-hood and body-control module applications. The device uses a 10/1000 μs test waveform with 0.01% duty cycle, and its forward voltage is 3.5 V at 25 A - consistent with P4KE220A and lower-voltage variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at 1 mA - defines reliable conduction onset threshold for overvoltage protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | DO-214AA package (smaller footprint), 300 W PPPM, same VBR range but higher VC (38.9 V) | Preferred for space-constrained PCBs where thermal mass is less critical | Select SMBJ24A only if board layout allows smaller SMC/SMB package and 38.9 V clamping is acceptable |
| 1.5KE24A | Same DO-41 package, higher PPPM (1500 W), higher VC (39.4 V), non-AEC-Q101 rated | Suitable for industrial mains-connected equipment requiring higher energy absorption | Choose 1.5KE24A when surge energy exceeds 400 W but automotive qualification is not required |
Compared with SMBJ24A and 1.5KE24A, the P4KE24AHE3/54 uniquely balances AEC-Q101 qualification, DO-41 legacy compatibility, and precise 33.2 V clamping - making it optimal for cost-sensitive automotive and industrial designs where thermal derating and regulatory compliance are jointly critical.

FAQ
What is the breakdown voltage tolerance of the P4KE24AHE3/54?
The P4KE24AHE3/54 has a specified breakdown voltage (VBR) range of 22.8 V to 25.2 V at 1 mA test current, representing ±5% tolerance around the nominal 24 V rating. This tight distribution ensures consistent clamping onset across production lots and supports deterministic overvoltage margin analysis in safety-critical circuits.
Is the P4KE24AHE3/54 suitable for bidirectional transient protection?
No, the P4KE24AHE3/54 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the P4KE24CA variant. Using P4KE24AHE3/54 in AC-coupled or symmetrical signal paths would result in unintended forward conduction during negative half-cycles.
Does the HE3 suffix on P4KE24AHE3/54 indicate AEC-Q101 qualification?
Yes, the "HE3" suffix explicitly denotes RoHS-compliant construction with AEC-Q101 qualification. This distinguishes it from the "E3" suffix version (e.g., P4KE24A-E3/54), which is commercial-grade only. The HE3 variant undergoes extended stress testing including temperature cycling, humidity bias, and high-temperature operating life per AEC-Q101 requirements.
What is the maximum allowable lead temperature during soldering for P4KE24AHE3/54?
The P4KE24AHE3/54 supports solder dip at up to 275 °C for 10 seconds maximum, per JESD22-B106. Reflow profiles must comply with JEDEC J-STD-020, and the device's matte tin-plated leads meet J-STD-002 and JESD22-B102 solderability standards - ensuring reliable wetting without intermetallic degradation.
How does the clamping voltage of P4KE24AHE3/54 compare to its breakdown voltage?
The P4KE24AHE3/54 clamps at 33.2 V when subjected to its rated 12.0 A peak pulse current (IPPM), yielding a clamping ratio (VC/VBR) of approximately 1.31. This low ratio reflects efficient avalanche conduction and minimal voltage overshoot - critical for protecting 24 V-rated ICs with 36 V absolute maximum ratings.
