Product details
Overview
P6KE39A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on power and signal lines. It features 37.1 V minimum breakdown voltage (VBR), 33.3 V standoff voltage (VWM), 53.9 V maximum clamping voltage (VC) at 11.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and ICs in automotive power supplies.
For engineers reviewing the P6KE39A-E3/54 datasheet, P6KE39A-E3/54 pinout, P6KE39A-E3/54 application, or P6KE39A-E3/54 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and DO-15 lead-form compatibility with legacy PCB footprints.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (33.3 V), it avalanches at VBR (37.1–41.0 V) and limits transient voltage to ≤53.9 V at 11.1 A IPPM. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance.
Rated for -55 °C to +175 °C operating junction temperature, it delivers 5.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C and withstands 100 A non-repetitive forward surge (8.3 ms half-sine). The device is RoHS-compliant (E3 suffix) and meets JESD 201 Class 1A whisker test requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 33.3 V - maximum continuous reverse working voltage before avalanche conduction begins |
| VBR (min/max) | 37.1 V / 41.0 V at 1.0 mA - ensures reliable turn-on within defined tolerance band for predictable clamping onset |
| VC @ IPPM | 53.9 V at 11.1 A - maximum clamped voltage during 10/1000 μs transient, directly limiting stress on downstream components |
| PPPM | 600 W - peak pulse power handling capability defines survivability against standard lightning/surge waveforms |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance enables effective heat transfer to PCB copper or heatsink |
| IFSM | 100 A - peak forward surge current rating supports robustness against accidental polarity reversal events |
| TJ max. | +175 °C - high junction temperature rating allows operation in under-hood automotive or industrial environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | DO-214AA package; 36 V VWM, 58.1 V VC @ 10.3 A; 600 W rating; same 10/1000 μs waveform | Higher clamping voltage (+4.2 V) and lower IPPM (-0.8 A); surface-mount only | Select when board space constraints require SMD layout and thermal design accommodates SMB footprint |
| 1.5KE39A | Same DO-15 package; identical VWM/VBR/VC specs; 1500 W PPPM; higher IFSM (200 A) | Over-specified power handling increases cost and may reduce surge lifetime consistency at lower energies | Choose only if system-level testing confirms need for >600 W surge margin or legacy 1.5KE footprint reuse |
Compared with SMBJ36A and 1.5KE39A, P6KE39A-E3/54 offers optimal balance of clamping precision (VC/VBR = 1.42), through-hole manufacturability, and AEC-Q101 qualification - making it preferred for cost-sensitive, high-volume automotive and industrial power rail protection where DO-15 lead spacing is fixed.

FAQ
What is the standoff voltage rating of the P6KE39A-E3/54?
The P6KE39A-E3/54 has a maximum reverse standoff voltage (VWM) of 33.3 V, meaning it remains non-conductive up to this DC or RMS voltage level under normal operation. This value is derived from the 10% below minimum breakdown voltage (37.1 V × 0.9 = 33.39 V, rounded per spec table), ensuring safe operation in 33 V nominal systems without leakage-induced power loss.
Is the P6KE39A-E3/54 suitable for automotive applications?
Yes, the P6KE39A-E3/54 is AEC-Q101 qualified per Vishay documentation (note "(1) AEC-Q101 qualified" in datasheet), confirming its suitability for automotive powertrain and body electronics. Its -55 °C to +175 °C operating range, 100 A IFSM, and DO-15 mechanical robustness meet critical automotive reliability requirements - though final qualification depends on system-level validation per vehicle OEM standards.
How does the clamping voltage of P6KE39A-E3/54 compare to its breakdown voltage?
The P6KE39A-E3/54 clamps to 53.9 V at 11.1 A peak pulse current, while its breakdown voltage ranges from 37.1 V to 41.0 V. This yields a clamping ratio (VC/VBR(min)) of 1.42 - indicating tight voltage control during surge events. That ratio is critical for protecting 36 V-rated ICs, as it guarantees the protected node never exceeds 53.9 V even under worst-case 600 W transients.
What is the thermal resistance specification for P6KE39A-E3/54?
The P6KE39A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured per JEDEC standards. This value reflects efficient heat transfer from the silicon die to the leads, enabling reliable 5.0 W steady-state power dissipation when leads are soldered to ≥1 sq-in copper area - essential for sustained operation in enclosed automotive junction boxes or industrial enclosures.
Does P6KE39A-E3/54 have bidirectional capability?
No, P6KE39A-E3/54 is a unidirectional TVS diode, as indicated by the "A" suffix (per Vishay naming convention: "A" = unidirectional, "CA" = bidirectional). It conducts only in reverse bias above VWM; forward conduction follows standard diode behavior with VF ≈ 3.5 V at 50 A. For bidirectional protection, the equivalent part is P6KE39CA-E3/54, which lacks polarity marking and clamps symmetrically.
