Product details
Overview
P6KE24AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 600 W peak pulse power (10/1000 μs), 22.8 V minimum breakdown voltage (VBR), 20.5 V standoff voltage (VWM), and clamps to ≤33.2 V at 18.1 A peak pulse current (IPPM). Used for IC and MOSFET protection in automotive and industrial power supply rails.
For engineers reviewing the P6KE24AHE3/54 datasheet, P6KE24AHE3/54 pinout, P6KE24AHE3/54 application, or P6KE24AHE3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, DO-15 mechanical compatibility, clamping performance under 10/1000 μs surge, and thermal resistance (RθJL = 20 °C/W).
Technical Context
This device operates as a voltage-clamping protector with glass-passivated junction and low incremental surge resistance. Its unidirectional configuration uses a cathode band marking and delivers fast response time (<1 ns) and excellent clamping ratio (VC/VBR ≈ 1.46 at IPPM), enabling robust transient suppression on DC power lines and signal paths.
Thermally rated for TJ up to +175 °C and qualified per AEC-Q101, the P6KE24AHE3/54 supports high-reliability automotive applications. Its 5.0 W steady-state power dissipation (PD) and 100 A non-repetitive forward surge capability (IFSM) allow integration into compact, high-surge environments without external heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 20.5 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC bias limit. |
| VBR (min/max) | 22.8 V / 25.2 V at 1.0 mA - Confirmed breakdown range ensures reliable turn-on during overvoltage events. |
| VC @ IPPM | ≤33.2 V at 18.1 A - Clamping voltage limits downstream component stress during 10/1000 μs transients. |
| PPPM | 600 W - Peak pulse power rating determines survivability of standardized lightning/surge waveforms. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance enables direct PCB trace heat sinking without added copper area. |

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 (SMB), 600 W rating, VWM = 20.5 V, VC = 38.9 V at 15.4 A | Surface-mount alternative with higher clamping voltage and lower IPPM; requires PCB rework. | Select SMBJ24A only if board space constraints mandate SMD mounting and clamping voltage margin allows. |
| 1.5KE24A | DO-201AD package, 1500 W rating, VWM = 20.5 V, VC = 36.0 V at 41.7 A | Larger through-hole package with higher surge capacity but slower thermal response and no AEC-Q101 qualification. | Choose 1.5KE24A for non-automotive applications requiring higher single-pulse energy absorption. |
Compared with SMBJ24A and 1.5KE24A, the P6KE24AHE3/54 offers AEC-Q101 qualification, tighter clamping (33.2 V vs. 36–38.9 V), and DO-15 compatibility with legacy through-hole designs-making it optimal for cost-sensitive, automotive-qualified power rail protection.

FAQ
What is the maximum clamping voltage of the P6KE24AHE3/54 under standard surge conditions?
The P6KE24AHE3/54 has a maximum clamping voltage (VC) of 33.2 V when subjected to its rated 10/1000 μs peak pulse current of 18.1 A. This value is measured per JEDEC standards and guarantees predictable overvoltage limiting for downstream components such as MOSFETs or interface ICs. The P6KE24AHE3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KE24AHE3/54 suitable for automotive applications?
Yes, the P6KE24AHE3/54 is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and infotainment power supplies. Its DO-15 package, 175 °C maximum junction temperature, and validated surge performance make it appropriate for under-hood and cabin environments. The P6KE24AHE3/54 meets stringent automotive qualification tests for thermal cycling, humidity, and high-temperature reverse bias.
How does the P6KE24AHE3/54 differ from bidirectional TVS diodes like P6KE24CA?
The P6KE24AHE3/54 is unidirectional and features a cathode band for polarity identification, whereas P6KE24CA is bidirectional with no polarity marking and symmetric clamping in both directions. The P6KE24AHE3/54 provides lower forward voltage drop (VF = 3.5 V at 50 A) and is intended for DC line protection where only positive transients occur. Bidirectional variants are used in AC or differential signal lines.
What is the standoff voltage (VWM) and why is it critical for P6KE24AHE3/54 selection?
The P6KE24AHE3/54 has a standoff voltage (VWM) of 20.5 V, meaning it remains non-conductive below this DC or RMS voltage level, with leakage current ≤1 μA. This parameter ensures the device does not interfere with normal circuit operation while providing precise overvoltage thresholding. Selecting a P6KE24AHE3/54 with correct VWM prevents false triggering on 24 V nominal rails with typical ripple and tolerance margins.
Does the P6KE24AHE3/54 require heatsinking in typical applications?
No, the P6KE24AHE3/54 does not require external heatsinking for transient suppression duty cycles (e.g., <0.01 % duty cycle per datasheet), thanks to its low RθJL of 20 °C/W and ability to dissipate 5.0 W continuously on an infinite heatsink. In practice, standard PCB copper traces connected to its leads provide sufficient thermal path. The P6KE24AHE3/54's thermal design supports direct integration into compact power supply layouts without added thermal management.
