Product details
Overview
P4KE24CHE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® 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 min/max = 22.8 V / 25.2 V), 20.5 V stand-off 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 P4KE24CHE3/73 datasheet, P4KE24CHE3/73 pinout, P4KE24CHE3/73 application, or P4KE24CHE3/73 equivalent, this AEC-Q101 qualified TVS diode supports automotive-grade ESD and surge protection in power supply inputs, sensor interfaces, and MOSFET gate drivers where stable clamping performance and low leakage (<1 μA at VWM) are required.
Technical Context
The P4KE24CHE3/73 employs a glass-passivated silicon junction optimized for fast response (<1 ns) to transient events and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on positive-going surges while blocking reverse leakage below 1 μA at 20.5 V.
Thermal design is supported by RθJL = 66 °C/W (junction-to-lead) and operation up to TJ = +175 °C, with derating applied above 25 °C ambient per Fig. 2. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 2 whisker resistance (HE3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at 1.0 mA - defines reliable conduction onset under surge conditions |
| VWM | 20.5 V - maximum continuous DC or RMS operating voltage before leakage exceeds 1 μA |
| VC @ IPPM | 33.2 V at 12.0 A - clamped voltage during 400 W 10/1000 μs transient, limiting stress on downstream ICs |
| IPPM | 12.0 A - peak surge current capability with defined waveform, directly usable for IEC 61000-4-5 Level 3 compliance margining |
| PPPM | 400 W - peak pulse power handling with 0.01 % duty cycle, enabling repetitive surge suppression in industrial controls |
| TJ max. | +175 °C - high-temperature operation support for under-hood automotive and high-power converter applications |

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump transients up to 35 V and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary clamping element placed between input fuse and DC-DC converter input. Use Value: Limits voltage to ≤33.2 V during 12 A surge, protecting downstream LDOs and microcontrollers rated for 36 V absolute max. |
Use Scenario: Analog output lines from pressure/temperature sensors in PLC I/O modules subject to field wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional shunt protector on 4–20 mA loop or 0–10 V analog output traces. Use Value: Sub-μA leakage at 20.5 V ensures <0.01 % full-scale error in precision analog circuits; 1 ns response prevents latch-up in op-amps. |
| MOSFET Gate Driver Protection | Consumer Power Adapter Input Stage |
Use Scenario: High-side N-channel MOSFET gate drive circuits in motor controllers experiencing Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Cathode tied to gate, anode to source; clamps negative-going gate-source transients. Use Value: 33.2 V clamping prevents gate oxide breakdown in 30 V-rated MOSFETs; low CJ avoids signal distortion at PWM frequencies >100 kHz. |
Use Scenario: Secondary-side DC bus in AC-DC adapters subjected to lightning-induced surges on mains-connected outputs. IC Role / Device Role / Timing Role: Stand-off voltage matched to 24 V nominal output; placed across bulk capacitor terminals. Use Value: 400 W pulse rating absorbs multiple 10/1000 μs events without parameter shift; AEC-Q101 grade ensures production longevity. |
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; 600 W PPPM; 38.9 V VC @ 15.4 A; 1.5× larger footprint | Higher power handling but requires PCB area increase; better suited for 1.2/50 μs lightning surges | Select SMBJ24A when surge energy exceeds 400 W limits or when board layout allows SMC/SMB package |
| 1.5KE24A | Same DO-41 package; 1500 W PPPM; 38.7 V VC @ 38.8 A; higher leakage (5 μA at VWM) | Higher surge capacity but looser VBR tolerance (±10 %) and reduced precision in low-leakage designs | Choose 1.5KE24A only for non-precision, high-energy industrial surge zones where leakage <1 μA is not critical |
Compared with SMBJ24A and 1.5KE24A, the P4KE24CHE3/73 delivers optimal balance of AEC-Q101 reliability, tight 5 % VBR tolerance, sub-μA leakage, and compact DO-41 fit-making it preferred for space-constrained automotive and precision industrial protection where consistent clamping voltage and long-term stability are mandatory.

FAQ
What is the breakdown voltage range for P4KE24CHE3/73?
The P4KE24CHE3/73 has a guaranteed breakdown voltage range of 22.8 V to 25.2 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This 5 % tolerance ensures precise and repeatable clamping onset across production lots, critical for protecting 24 V nominal systems without premature conduction.
Is P4KE24CHE3/73 suitable for automotive applications?
Yes, the P4KE24CHE3/73 carries the HE3 suffix indicating AEC-Q101 qualification, including stress testing for temperature cycling, high-temperature reverse bias, and ESD. Its +175 °C max junction temperature and robust DO-41 construction make it approved for under-hood and body-control module use in passenger vehicles and commercial vehicles.
What does the "HE3" suffix mean in P4KE24CHE3/73?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike standard E3 variants, HE3 guarantees automotive-grade reliability, including enhanced plating adhesion and long-term stability under thermal-humidity bias conditions required for automotive electronics.
How does P4KE24CHE3/73 compare to P4KE24A-E3/73?
The P4KE24CHE3/73 differs from P4KE24A-E3/73 solely in qualification level: HE3 is AEC-Q101 qualified and Class 2 whisker-tested, while E3 is commercial-grade only. Electrically and dimensionally identical, both share same VBR, VWM, VC, and DO-41 package-but only P4KE24CHE3/73 is approved for automotive production.
What is the maximum clamping voltage of P4KE24CHE3/73 under surge conditions?
The P4KE24CHE3/73 clamps to a maximum of 33.2 V at its rated peak pulse current of 12.0 A (10/1000 μs waveform). This value is guaranteed across temperature and lifetime, enabling accurate system-level overvoltage margining for 36 V-rated ICs and MOSFETs in automotive and industrial power stages.
