Product details
Overview
P6KE30CHE3/54 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 600 W peak pulse power (10/1000 μs), 30 V nominal breakdown voltage (28.5–31.5 V at 1 mA), 41.4 V maximum clamping voltage at 14.5 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability - deployed in engine control units and battery management systems.
For engineers reviewing the P6KE30CHE3/54 datasheet, P6KE30CHE3/54 pinout, P6KE30CHE3/54 application, or P6KE30CHE3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, thermal resistance (20 °C/W junction-to-lead), unidirectional polarity marking, and RoHS-compliant HE3 whisker-tested leads suitable for high-reliability soldering processes.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents <1 μA leakage at 25.6 V stand-off voltage; during transients exceeding 28.5 V, it avalanches rapidly (<1 ns response) to clamp the line at ≤41.4 V while diverting up to 14.5 A (10/1000 μs). Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
The device is rated for -55 °C to +175 °C operating junction temperature, with thermal derating starting above 25 °C ambient. Power dissipation is limited to 5.0 W on infinite heatsink at TL = 75 °C, and it withstands 100 A non-repetitive forward surge (8.3 ms half-sine), making it suitable for inductive load switching protection in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 28.5–31.5 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| Stand-off Voltage VWM | 25.6 V - maximum continuous DC or RMS voltage the device blocks without leakage exceeding 1 μA |
| Clamping Voltage VC | 41.4 V at 14.5 A IPPM - limits transient voltage seen by downstream circuitry during worst-case surge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Same VBR range (28.5–31.5 V), but SMC package (higher thermal mass); 600 W rating; 41.4 V VC; unidirectional | Higher board-level robustness due to larger SMC footprint; better suited for high-volume automated placement | Select SMBJ30A when PCB layout allows SMC package and higher thermal cycling endurance is required |
| 1.5KE30A | Same DO-15 package and electrical specs, but commercial-grade (non-AEC-Q101); identical VBR, VC, and PPPM | Lacks automotive qualification; not recommended for safety-critical or extended-temperature deployments | Choose 1.5KE30A only for cost-sensitive consumer or industrial applications where AEC-Q101 is not mandated |
Compared with SMBJ30A and 1.5KE30A, P6KE30CHE3/54 uniquely combines AEC-Q101 qualification, HE3 whisker-resistant leads, and DO-15 form factor - enabling drop-in replacement in legacy automotive designs without layout change while ensuring long-term solder joint reliability.

FAQ
What is the maximum clamping voltage of P6KE30CHE3/54 under specified surge conditions?
The P6KE30CHE3/54 exhibits a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current of 14.5 A using the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper limit of voltage imposed on the protected circuit during a worst-case transient event, ensuring compatibility with 36 V-rated downstream components.
Is P6KE30CHE3/54 suitable for automotive applications?
Yes, P6KE30CHE3/54 is AEC-Q101 qualified and manufactured with HE3 whisker-resistant leads, making it suitable for automotive applications including engine control units, body electronics, and battery management systems. Its -55 °C to +175 °C operating junction temperature range and validation against HTOL, TCT, and ESD stress tests confirm its readiness for under-hood deployment.
How does the P6KE30CHE3/54 differ from the standard P6KE30A variant?
The P6KE30CHE3/54 differs from P6KE30A in three verified aspects: (1) HE3 suffix denotes JESD 201 Class 2 whisker resistance, (2) E3/54 ordering code specifies 4000-unit 13-inch paper tape and reel packaging, and (3) it is explicitly designated AEC-Q101 qualified per Vishay documentation - whereas base P6KE30A is commercial grade only.
What is the standoff voltage rating for P6KE30CHE3/54?
The standoff voltage (VWM) for P6KE30CHE3/54 is 25.6 V - the maximum DC or RMS voltage the device reliably blocks while maintaining reverse leakage current ≤1 μA at 25 °C. This rating ensures safe operation below the avalanche threshold during normal system operation, providing margin against ripple and tolerance drift before clamping initiates.
Can P6KE30CHE3/54 be used in bi-directional protection configurations?
No, P6KE30CHE3/54 is a uni-directional TVS diode, indicated by the "A" suffix and cathode band marking. For bi-directional applications, Vishay specifies the "CA" suffix (e.g., P6KE30CA). Using P6KE30CHE3/54 in reverse-biased configurations risks permanent forward conduction and failure; always verify polarity alignment in schematic and layout.
