Product details
Overview
P6KE24HE3/54 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 a 24 V nominal breakdown voltage (VBR = 22.8–25.2 V at 1 mA), 20.5 V maximum stand-off voltage (VWM), 33.2 V clamping voltage (VC) at 18.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive ECUs to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE24HE3/54 datasheet, P6KE24HE3/54 pinout, P6KE24HE3/54 application, or P6KE24HE3/54 equivalent, this AEC-Q101 qualified TVS offers verified surge robustness, low clamping ratio (VC/VWM ≈ 1.62), and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering - critical for high-reliability automotive and industrial power rail protection design.
Technical Context
The P6KE24HE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to ESD and lightning-induced transients. Its uni-directional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 50 A surge, with thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient).
It is rated for -55 °C to +175 °C operating junction temperature, supports 100 A non-repetitive forward surge current (8.3 ms half-sine), and maintains stable clamping performance across temperature due to a +0.094 %/°C VBR temperature coefficient - ensuring predictable protection behavior under thermal stress in engine-bay electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at 1 mA - defines reliable avalanche initiation threshold for consistent clamping onset |
| VWM | 20.5 V - maximum continuous reverse voltage before leakage exceeds 1 μA; sets safe DC operating margin |
| VC @ IPPM | 33.2 V at 18.1 A (10/1000 μs) - limits protected circuit voltage during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capacity without failure under standardized surge waveform |
| IFSM | 100 A (8.3 ms half-sine) - withstands high-current inductive switching events like relay coil de-energization |
| TJ max. | +175 °C - enables placement near heat sources (e.g., power MOSFETs) without derating concerns |
| RθJL | 20 °C/W - allows direct thermal coupling to PCB copper pour or heatsinked lead for sustained power dissipation |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards; HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during positive surge on cathode |
| Cathode (banded end) | Avalanche clamping terminal | Connected to protected line (e.g., 24 V rail); initiates breakdown when voltage exceeds VWM |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive-grade temperature cycling, humidity, mechanical shock, and lifetime surge endurance |

| Low clamping ratio (VC/VWM = 1.62) | Minimizes overvoltage stress on downstream ICs while maintaining sufficient margin above system VMAX |
| RoHS-compliant, matte tin plating | Ensures compatibility with lead-free reflow and wave soldering processes per J-STD-002B Class 2 |
Applications

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 | Same VWM (20.5 V) and VC (38.9 V), but lower PPPM (400 W) and SMC (DO-214AB) package | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a load-dump simulation | Select only if space-constrained layout favors SMC footprint and surge requirements are ≤400 W |
| 1.5KE24A | Higher PPPM (1500 W), same DO-204AC package, but larger body (DO-201AD) and higher VC (39.4 V) | Better for extreme surges but increases protected IC stress due to 18.5 % higher clamping voltage | Prefer when system must survive >1 kV/100 Ω IEC 61000-4-5 surges, accepting higher VC trade-off |
Compared with SMAJ24A and 1.5KE24A, the P6KE24HE3/54 delivers optimal balance of AEC-Q101 reliability, 600 W surge capacity, and tight 33.2 V clamping in the compact DO-15 form factor - making it the preferred choice for cost-sensitive, thermally constrained automotive and industrial 24 V protection nodes.

FAQ
What is the clamping voltage of the P6KE24HE3/54 under standard test conditions?
The P6KE24HE3/54 has a maximum clamping voltage (VC) of 33.2 V when subjected to its rated peak pulse current of 18.1 A using the 10/1000 μs waveform. This value is measured at the device terminals under controlled lab conditions per JEDEC standards and reflects the upper limit of voltage seen by downstream components during surge events - a key parameter used to verify compatibility with the absolute maximum ratings of protected ICs in the P6KE24HE3/54 application circuit.
Is the P6KE24HE3/54 suitable for automotive applications?
Yes, the P6KE24HE3/54 is explicitly AEC-Q101 qualified (denoted by the HE3 suffix), having passed stress tests including temperature cycling, high-temperature reverse bias, and surge endurance per automotive reliability standards. Its -55 °C to +175 °C operating range, 100 A surge rating, and UL recognition (QVGQ2) make the P6KE24HE3/54 appropriate for under-hood ECUs, body control modules, and ADAS power supplies where transient immunity is critical.
How does the P6KE24HE3/54 differ from the P6KE24A-E3/54 variant?
The P6KE24HE3/54 differs from P6KE24A-E3/54 solely in qualification level: the HE3 suffix indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas the E3 suffix denotes commercial-grade RoHS compliance only. Both share identical electrical specs (VBR, VWM, VC, PPPM) and DO-204AC packaging, but the P6KE24HE3/54 is required for automotive production use where component-level automotive qualification is mandated.
What is the maximum continuous reverse voltage the P6KE24HE3/54 can block?
The P6KE24HE3/54 has a maximum working peak reverse voltage (VWM) of 20.5 V - meaning it can continuously block up to 20.5 V in reverse bias while maintaining reverse leakage current below 1 μA at 25 °C. This value establishes the safe DC operating margin below the 22.8–25.2 V breakdown range and ensures stable operation on nominal 24 V systems where ripple and tolerance keep the rail within specification during normal operation of the P6KE24HE3/54.
Does the P6KE24HE3/54 require a heatsink for standard operation?
No, the P6KE24HE3/54 does not require an external heatsink for transient suppression duty, as its 600 W rating applies to non-repetitive pulses (duty cycle ≤0.01 %). However, for sustained power dissipation, its thermal resistance is 20 °C/W junction-to-lead - so mounting with ≥1 cm² of 2 oz copper connected to the cathode lead provides adequate conduction cooling. The P6KE24HE3/54's RθJA of 75 °C/W means ambient operation remains within limits up to ~5.0 W continuous dissipation only with significant PCB copper area.
