Product details
Overview
P6KE30HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 30 V breakdown voltage (VBR min/max = 28.5–31.5 V), 41.4 V maximum clamping voltage at 14.5 A peak pulse current, 600 W peak pulse power rating (10/1000 µs waveform), and AEC-Q101 qualification for automotive-grade reliability - deployed in engine control units, infotainment power inputs, and industrial sensor interfaces.
For engineers reviewing the P6KE30HE3/54 datasheet, P6KE30HE3/54 pinout, P6KE30HE3/54 application, or P6KE30HE3/54 equivalent, key selection criteria include its DO-204AC (DO-15) package compatibility, 25.6 V stand-off voltage (VWM), 1.0 µA max reverse leakage at VWM, and thermal resistance of 20 °C/W (junction-to-lead), critical for surge-limited PCB layouts with constrained heatsinking.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 µA leakage at 25.6 V), then rapidly avalanches below 41.4 V to divert transient energy away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance across repeated 10/1000 µs pulses at 0.01% duty cycle.
The device is rated for -55 °C to +175 °C operating junction temperature, with thermal derating starting above 25 °C ambient. Its 100 A IFSM (8.3 ms half-sine) and 20 °C/W RθJL support robust handling of inductive switch-off surges in automotive 12 V systems without external heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V - Ensures reliable avalanche initiation before downstream component damage thresholds |
| VWM | 25.6 V - Maximum continuous DC operating voltage without significant leakage |
| VC @ IPPM | 41.4 V at 14.5 A - Clamping voltage limiting transient overshoot during 600 W surge events |
| IPPM | 14.5 A - Peak pulse current capability with 10/1000 µs waveform, defining surge-handling margin |
| PPPM | 600 W - Sustained transient energy absorption capacity per pulse, critical for ISO 7637-2 compliance |
| TJ max | +175 °C - Enables operation in under-hood automotive environments without thermal shutdown |
| RθJL | 20 °C/W - Low thermal resistance allows efficient heat transfer to PCB copper or lead frame |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Same VBR range (28.5–31.5 V), but SMA package (surface-mount); lower PPPM = 400 W | Requires rework for through-hole legacy boards; better suited for space-constrained new designs | Select SMAJ30A only if board layout supports SMD placement and 400 W surge margin is sufficient |
| 1.5KE30A | Same DO-15 package and VBR, but commercial-grade (non-AEC-Q101); higher VC = 48.4 V at same IPPM | Lacks automotive qualification; unsuitable for safety-critical vehicle subsystems | Choose 1.5KE30A only for cost-sensitive consumer applications where AEC-Q101 is not mandated |
Compared with SMAJ30A and 1.5KE30A, P6KE30HE3/54 uniquely delivers AEC-Q101 qualification in a through-hole DO-15 package with 600 W surge rating and 41.4 V clamping - making it the only option meeting ISO 16750-2 load dump and thermal cycling requirements for automotive power modules.

FAQ
What is the clamping voltage of P6KE30HE3/54 and how is it measured?
The P6KE30HE3/54 has a maximum clamping voltage (VC) of 41.4 V, measured at 14.5 A peak pulse current using a 10/1000 µs waveform per Fig. 1 in Vishay document 88369. This value represents the upper limit of voltage imposed on protected circuitry during a standardized surge event, ensuring downstream components remain within safe operating limits. The P6KE30HE3/54 achieves this clamping performance via controlled avalanche breakdown across its glass-passivated junction.
Is P6KE30HE3/54 suitable for automotive applications?
Yes, P6KE30HE3/54 is AEC-Q101 qualified (HE3 suffix), explicitly validated for automotive use per Vishay's documentation. It meets temperature cycling, humidity, mechanical shock, and surge endurance requirements for under-hood and cabin electronics. Its 175 °C max junction temperature, 600 W pulse rating, and DO-204AC mechanical robustness make P6KE30HE3/54 appropriate for engine control units, body controllers, and ADAS power supplies.
What does the 'HE3/54' suffix mean in P6KE30HE3/54?
The 'HE3' suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; '54' denotes the preferred package code for 13-inch paper tape and reel packaging (4000 units per reel). This distinguishes P6KE30HE3/54 from commercial-grade variants like P6KE30A-E3/54 (no AEC-Q101) and confirms full compliance with automotive supply chain traceability and reliability standards.
How does P6KE30HE3/54 compare to P6KE30A in terms of performance?
P6KE30HE3/54 shares identical electrical specifications (VBR, VC, PPPM) with P6KE30A but adds AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and enhanced process controls for automotive use. Both use DO-204AC packaging and have 25.6 V VWM, but only P6KE30HE3/54 is approved for safety-critical vehicle subsystems - making P6KE30HE3/54 the required choice where qualification evidence is mandatory.
What is the thermal resistance of P6KE30HE3/54 and why does it matter?
P6KE30HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, per Vishay document 88369. This low value enables efficient heat transfer from the silicon die to the PCB copper or chassis via the leads, critical for sustaining repetitive surge events without thermal runaway. In automotive 12 V systems experiencing frequent load dumps, this RθJL ensures P6KE30HE3/54 remains within its 175 °C TJ limit even with minimal copper pour.
