Product details
Overview
P4KE24CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 24 V breakdown voltage (VBR = 22.8–25.2 V at 1.0 mA), 20.5 V stand-off voltage (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 - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P4KE24CHE3/54 datasheet, P4KE24CHE3/54 pinout, P4KE24CHE3/54 application, or P4KE24CHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, clamping performance under surge conditions, and direct alternatives for board-level ESD/transient hardening.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at VWM), while the DO-41 package supports manual or wave-solder assembly with matte tin-plated leads compliant to J-STD-002.
The device is rated for 40 A non-repetitive forward surge (8.3 ms half-sine), 175 °C max junction temperature, and exhibits 0.094 %/°C temperature coefficient of VBR. Its thermal resistance is 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient, LLead = 10 mm), enabling reliable operation in thermally constrained environments without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping onset |
| VWM | 20.5 V - maximum continuous reverse operating voltage before leakage rises above 1.0 μA |
| VC @ IPPM | 33.2 V at 12.0 A - clamped voltage during 10/1000 μs surge, limiting stress on protected ICs |
| PPPM | 400 W - peak transient power handling capability per single 10/1000 μs pulse |
| IFSM | 40 A - withstands 8.3 ms half-sine surge without failure, critical for inductive load switching events |
| TJ max | +175 °C - enables use in under-hood automotive and high-temperature industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; cathode indicated by color band on body. Matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance (HE3 suffix). Dimensions: 25.4 mm min length, 5.2 mm max body diameter, 0.86 mm lead diameter.
| Pin/Terminal | Circuit Role | Design Meaning |

Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | DO-214AA package; 24 V VBR; 600 W PPPM; 38.9 V VC @ 15.4 A | Higher power rating but larger footprint; lower surge current density per mm² | Select SMBJ24A when higher peak power margin is required and PCB space allows SMC/SMB footprint. |
| 1.5KE24A | DO-201AD package; same VBR/VWM; 1500 W PPPM; 38.7 V VC @ 38.8 A | Higher surge capacity but longer lead inductance; less suitable for fast-edge transients | Choose 1.5KE24A for legacy designs requiring higher single-pulse energy absorption where layout permits larger leaded package. |
Compared with SMBJ24A and 1.5KE24A, P4KE24CHE3/54 offers optimal balance of AEC-Q101 compliance, compact DO-41 form factor, and precise 20.5 V standoff for 24 V systems - making it preferred for space-constrained automotive and industrial control boards where qualification and repeatability are mandatory.

FAQ
What is the breakdown voltage range of the P4KE24CHE3/54?
The P4KE24CHE3/54 has a specified breakdown voltage (VBR) range of 22.8 V to 25.2 V at a test current of 1.0 mA. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage protection design for 24 V nominal systems. The value is measured per ANSI/IEEE C62.35 standards and confirmed in Vishay's official datasheet revision 16-Sep-2021.
Is the P4KE24CHE3/54 qualified for automotive applications?
Yes, the P4KE24CHE3/54 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Document Number: 88365, Revision: 16-Sep-2021). The HE3 suffix denotes AEC-Q101 qualification, covering stress tests including temperature cycling, high-temperature reverse bias, and ESD. This makes P4KE24CHE3/54 suitable for under-hood and chassis-mounted automotive electronics.
What is the clamping voltage of the P4KE24CHE3/54 under surge conditions?
The P4KE24CHE3/54 clamps to a maximum of 33.2 V at its rated peak pulse current of 12.0 A (10/1000 μs waveform). This VC value is guaranteed across temperature and lot variations, ensuring downstream components like microcontrollers or transceivers remain within their absolute maximum voltage ratings during transient events.
Does the P4KE24CHE3/54 have polarity marking, and how is it identified?
Yes, the P4KE24CHE3/54 is unidirectional and features a cathode band - a visible color stripe on the epoxy body - indicating the cathode terminal. The anode is the unmarked lead. This marking aligns with JEDEC DO-41 conventions and is essential for correct orientation during PCB placement to ensure proper clamping function in 24 V rail protection circuits.
What package type and lead finish does the P4KE24CHE3/54 use?
The P4KE24CHE3/54 uses the DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads. It meets J-STD-002 solderability requirements and JESD 201 Class 2 whisker resistance. The HE3 suffix confirms both RoHS compliance and AEC-Q101 qualification, and the package is rated for solder dip at 275 °C for up to 10 seconds per JESD 22-B106.
