Product details
Overview
P6KE24CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 600 W peak pulse power (10/1000 μs), 22.8 V to 25.2 V breakdown voltage at 1 mA, 20.5 V stand-off voltage, 33.2 V maximum clamping voltage at 18.1 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE24CHE3/73 datasheet, P6KE24CHE3/73 pinout, P6KE24CHE3/73 application, or P6KE24CHE3/73 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, thermal resistance (RθJL = 20 °C/W), RoHS-compliant matte tin plating, and compatibility with J-STD-002 solderability standards.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at 20.5 V).
Designed for single-pulse and low-duty-cycle repetitive transients, it supports 100 A non-repetitive forward surge current (8.3 ms half-sine) and derates linearly above 25 °C ambient-maintaining 5.0 W power dissipation at TL = 75 °C on infinite heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 20.5 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 33.2 V at 18.1 A - clamping voltage during 10/1000 μs surge; limits stress on protected circuitry |
| PPPM | 600 W - peak pulse power handling capability per standard 10/1000 μs waveform |
| RθJL | 20 °C/W - thermal resistance from junction to lead; enables direct PCB copper pour heat sinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | Lower peak pulse power (400 W), SMA package (surface-mount), higher RθJA (110 °C/W) | Better suited for space-constrained PCB layouts but requires thermal relief pads for equivalent power handling | Select when board area is limited and surge duty cycle is low; verify thermal margin at full 18.1 A IPPM |
| 1.5KE24A | Same DO-15 package, identical VBR/VC, but only commercial-grade (not AEC-Q101 qualified) | Lacks automotive qualification; suitable for industrial/commercial power supplies where qualification is not mandated | Choose for cost-sensitive non-automotive designs requiring identical electrical specs and through-hole assembly |
Compared with P6KE24CHE3/73, SMAJ24A trades package size and mounting method for reduced surge capacity, while 1.5KE24A matches form/fit/function but omits AEC-Q101 validation-making P6KE24CHE3/73 the sole choice for production automotive systems requiring certified reliability.

FAQ
What is the clamping voltage of P6KE24CHE3/73 at its rated peak pulse current?
The P6KE24CHE3/73 has a maximum clamping voltage (VC) of 33.2 V at its rated peak pulse current (IPPM) of 18.1 A under the standard 10/1000 μs waveform. This value is guaranteed across temperature and ensures downstream components see no more than 33.2 V during surge events. The P6KE24CHE3/73 achieves this with low incremental surge resistance and fast avalanche response.
Is P6KE24CHE3/73 suitable for automotive applications?
Yes, P6KE24CHE3/73 is AEC-Q101 qualified and specifically designed for automotive use. Its construction includes glass-passivated junction, matte tin-plated leads compliant with J-STD-002, and operation up to +175 °C junction temperature. The HE3 suffix confirms AEC-Q101 qualification, making P6KE24CHE3/73 appropriate for engine control, body electronics, and ADAS modules.
What does the "HE3" suffix mean in P6KE24CHE3/73?
The "HE3" suffix in P6KE24CHE3/73 indicates RoHS-compliant, AEC-Q101 qualified construction with JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions and confirms compliance with automotive reliability standards, UL 94 V-0 flammability, and halogen-free materials per JEDEC JS709A.
How does P6KE24CHE3/73 differ from P6KE24A-E3/73?
P6KE24CHE3/73 is the AEC-Q101 qualified version, whereas P6KE24A-E3/73 is commercial grade only. Both share identical electrical parameters (VBR, VC, PPPM) and DO-15 packaging, but only P6KE24CHE3/73 undergoes automotive stress testing (HTGB, HTRB, TCT). The "H" in HE3 explicitly denotes AEC-Q101 qualification-critical for automotive production releases.
What is the maximum reverse leakage current for P6KE24CHE3/73 at its stand-off voltage?
The maximum reverse leakage current (ID) for P6KE24CHE3/73 is 1.0 μA at its stand-off voltage (VWM) of 20.5 V and TA = 25 °C. This low leakage ensures minimal power loss in standby mode and prevents false triggering in high-impedance circuits. The P6KE24CHE3/73 maintains this specification across its full operating temperature range (-55 °C to +175 °C).
