Product details
Overview
P4KE24-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 24 V breakdown voltage (VBR min/max = 22.8 V / 25.2 V), 20.5 V standoff voltage (VWM), 33.2 V clamping voltage at 12 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE24-E3/54 datasheet, P4KE24-E3/54 pinout, P4KE24-E3/54 application, or P4KE24-E3/54 equivalent, key selection criteria include clamping performance under 12 A surge, thermal resistance (RθJL = 66 °C/W), AEC-Q101 qualification status, RoHS compliance, and compatibility with manual or wave soldering per J-STD-002.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping protection device across DC power rails or signal lines, activating when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %), low incremental surge resistance, and fast response time (<1 ns).
The device complies with AEC-Q101 for automotive-grade reliability and supports 1.5 W steady-state power dissipation at TL = 75 °C. Its DO-41 package enables through-hole mounting with matte tin-plated leads, rated for solder dip up to 275 °C for 10 s per JESD 22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at IT = 1.0 mA - defines precise conduction onset range for reliable overvoltage triggering |
| VWM | 20.5 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 33.2 V at 12.0 A - clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 400 W - peak transient energy absorption capability without failure |
| RθJL | 66 °C/W - thermal resistance from junction to lead, critical for PCB trace heat sinking design |
| TJ max | +175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| IF surge | 40 A at 8.3 ms half-sine - forward surge rating for unidirectional polarity handling |
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 22-B102 intermetallic growth requirements.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs from load dump and alternator transients in passenger vehicles and commercial trucks. IC Role / Device Role / Timing Role: Unidirectional clamping device placed between battery rail and regulator input, conducting only during negative-going transients relative to ground. Use Value: Limits voltage to ≤33.2 V during 12 A surges, preventing damage to downstream LDOs and microcontrollers rated for 36 V absolute maximum. | Use Scenario: Shielding analog output lines of pressure/temperature sensors in factory automation PLC modules from ESD and relay-switching noise. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF) shunt protector on 4–20 mA current loop outputs, grounded at system common. Use Value: Clamps fast-rising transients within <1 ns while maintaining signal integrity due to minimal parasitic capacitance and low leakage (<1 μA at 20.5 V). |
| Telecom DC Power Input Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Safeguarding PoE-powered network switches and base stations against lightning-induced surges on 48 V DC input rails. IC Role / Device Role / Timing Role: Primary-level TVS mounted at board edge, coordinated with upstream fuses and secondary-stage MOVs. Use Value: Absorbs 400 W transient energy without degradation, enabling compliance with ITU-T K.21 basic protection level for outdoor telecom equipment. | Use Scenario: Suppressing inductive kickback from brushed DC motors in smart home appliances (e.g., vacuum cleaners, washing machines). IC Role / Device Role / Timing Role: Freewheeling path across motor terminals, diverting stored inductive energy back into the supply rail. Use Value: Withstands 40 A 8.3 ms surge current and operates up to +175 °C, ensuring reliability in thermally constrained motor control PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Surface-mount SMB package; 24 V VBR; 600 W PPPM; RθJA = 35 °C/W | Requires reflow-compatible layout; better thermal performance on copper pour but no through-hole mechanical retention | Select SMBJ24A for space-constrained, high-volume SMT designs where automated assembly is preferred. |
| 1.5KE24A | Same DO-41 package; 24 V VBR; 1500 W PPPM; higher IPPM (65.2 A); larger junction capacitance | Higher surge margin for heavy industrial environments; less suitable for high-speed signal lines due to higher CJ | Choose 1.5KE24A when legacy DO-41 footprint must be retained and surge immunity >400 W is required. |
Compared with SMBJ24A and 1.5KE24A, the P4KE24-E3/54 offers balanced surge capability (400 W), proven AEC-Q101 qualification, and cost-effective through-hole assembly-making it optimal for mid-tier automotive modules and industrial controls where reliability and manufacturability are jointly prioritized.

FAQ
What is the breakdown voltage tolerance of P4KE24-E3/54?
The P4KE24-E3/54 has a specified breakdown voltage range of 22.8 V to 25.2 V at test current IT = 1.0 mA, corresponding to a ±5 % tolerance around the nominal 24 V rating. This tight tolerance ensures predictable clamping behavior across production lots and temperature ranges, critical for designs where overvoltage margin is tightly constrained.
Is P4KE24-E3/54 suitable for automotive applications?
Yes, P4KE24-E3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C, making it suitable for under-hood and cabin-mounted automotive electronics. Its glass-passivated junction, DO-41 mechanical robustness, and validated surge performance align with requirements for engine control units, body controllers, and ADAS sensor interfaces.
What is the maximum clamping voltage of P4KE24-E3/54 during a surge event?
The maximum clamping voltage (VC) of P4KE24-E3/54 is 33.2 V at a peak pulse current (IPPM) of 12.0 A with a 10/1000 μs waveform. This value represents the upper limit of voltage seen by downstream components during standardized surge events, directly informing safe operating area calculations for protected ICs and regulators.
Does P4KE24-E3/54 have RoHS compliance documentation?
Yes, the "E3" suffix in P4KE24-E3/54 indicates RoHS-compliant construction per EU Directive 2011/65/EU, with matte tin-plated leads and UL 94 V-0 compliant epoxy molding compound. Full compliance data, including substance declarations and test reports, is available through Vishay's material categorization portal (www.vishay.com/doc?99912).
Can P4KE24-E3/54 be used in bidirectional configurations?
No, P4KE24-E3/54 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" suffix (e.g., P4KE24CA), which lacks polarity marking and provides symmetrical clamping in both directions. Using P4KE24-E3/54 in bidirectional circuits would result in unintended forward conduction during negative transients.
