Product details
Overview
P6KE100AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 95.0–105 V breakdown voltage (VBR), 85.5 V maximum standoff voltage (VWM), 137 V clamping voltage at 4.4 A peak pulse current (IPPM), 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification - deployed in automotive body control modules to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE100AHE3/54 datasheet, P6KE100AHE3/54 pinout, P6KE100AHE3/54 application, or P6KE100AHE3/54 equivalent, key selection criteria include verified clamping performance under 10/1000 µs surge, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, RoHS-compliant matte tin leads, and AEC-Q101 qualification for automotive-grade reliability validation.
Technical Context
The P6KE100AHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transient overvoltages. Its unidirectional configuration provides cathode-marked polarity for DC rail protection, with clamping action triggered when reverse voltage exceeds VBR (95.0–105 V at 1.0 mA test current).
It sustains 600 W peak pulse power per 10/1000 µs waveform at TA = 25 °C, derating linearly above 25 °C per Fig. 2, and supports 100 A non-repetitive forward surge current (8.3 ms half-sine). Junction temperature range spans −55 °C to +175 °C, and thermal resistance from junction-to-lead is 20 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V at 1.0 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 85.5 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 137 V at 4.4 A - clamped voltage during 600 W transient, limiting stress on downstream ICs |
| PPPM | 600 W (10/1000 µs) - surge energy handling capacity compatible with ISO 7637-2 Pulse 5a load-dump profiles |
| IFSM | 100 A (8.3 ms half-sine) - withstands high-current inductive kick without failure |
| TJ max. | +175 °C - enables operation in under-hood automotive environments |
| RθJL | 20 °C/W - low thermal resistance supports PCB trace heat sinking without external heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | DO-214AA package; 100 V VWM, 111 V VC @ 5.4 A; 600 W rating; same AEC-Q101 qualification | Lower clamping voltage but larger footprint; requires PCB layout change | Select when lower VC is critical and board space allows SMB package |
| 1.5KE100A | DO-201AD package; identical VBR/VWM/VC specs; 1500 W rating; commercial grade only (no AEC-Q101) | Higher power handling but no automotive qualification; higher leakage at elevated temperature | Select for cost-sensitive industrial power supplies where AEC-Q101 is not required |
Compared with P6KE100AHE3/54, SMBJ100A offers tighter clamping in a surface-mount format ideal for automated assembly, while 1.5KE100A delivers higher surge margin in through-hole form but lacks automotive qualification - making P6KE100AHE3/54 the optimal choice for space-constrained, AEC-Q101–mandated automotive DC protection.

FAQ
What is the clamping voltage of the P6KE100AHE3/54 under maximum rated surge conditions?
The P6KE100AHE3/54 exhibits a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.4 A (10/1000 µs waveform), as specified in the Vishay datasheet Document Number 88369. This value ensures downstream components see limited overvoltage stress during transient events. The P6KE100AHE3/54 maintains this clamping performance across its full operating temperature range and is validated per AEC-Q101 stress testing protocols.
Is the P6KE100AHE3/54 suitable for automotive applications?
Yes, the P6KE100AHE3/54 is AEC-Q101 qualified (as confirmed by the HE3 suffix and datasheet Note 1), making it suitable for automotive applications including body control modules, infotainment power supplies, and lighting drivers. Its 175 °C maximum junction temperature, glass-passivated junction, and robust surge ratings align with under-hood environmental demands. The P6KE100AHE3/54 meets ISO 7637-2 Pulse 5a requirements when applied per recommended layout guidelines.
How does the P6KE100AHE3/54 differ from the commercial-grade P6KE100AE3/54?
The P6KE100AHE3/54 differs from P6KE100AE3/54 solely in qualification level: the "H" in HE3 denotes AEC-Q101 qualification, whereas E3 indicates commercial-grade RoHS compliance only. Both share identical electrical specifications (VBR, VWM, VC, PPPM), DO-15 packaging, and matte tin plating. The P6KE100AHE3/54 undergoes additional stress testing per AEC-Q101, including temperature cycling, HTRB, and UHAST, ensuring reliability in automotive deployments.
What is the standoff voltage rating for the P6KE100AHE3/54?
The P6KE100AHE3/54 has a maximum standoff voltage (VWM) of 85.5 V, meaning it remains in high-impedance state with ≤1.0 µA reverse leakage current up to this DC or RMS voltage level. This allows safe integration into 72–80 V nominal systems (e.g., 24 V automotive or industrial rails with ripple) without false triggering. The P6KE100AHE3/54's VWM is derived from its 95.0–105 V VBR range and ensures sufficient margin against normal operating transients.
Can the P6KE100AHE3/54 be used in bidirectional configurations?
No, the P6KE100AHE3/54 is a unidirectional TVS diode, as indicated by the "A" suffix (per Vishay's naming convention: "A" = unidirectional, "CA" = bidirectional). It conducts only in forward bias and clamps in reverse bias; using it in bidirectional circuits would leave positive-going transients unprotected. For bidirectional protection at ~100 V, the P6KE100CA variant must be selected - the P6KE100AHE3/54 is strictly for DC rail or polarized signal line protection.
