Product details
Overview
P6KE39AHE3/54 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 39 V breakdown voltage (VBR min/max: 37.1–41.0 V), 33.3 V stand-off voltage (VWM), 53.9 V clamping voltage at 11.1 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor interface protection and industrial I/O modules.
For engineers reviewing the P6KE39AHE3/54 datasheet, P6KE39AHE3/54 pinout, P6KE39AHE3/54 application, or P6KE39AHE3/54 equivalent, key selection criteria include verified AEC-Q101 qualification, DO-15 mechanical compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJL = 20 °C/W) critical for sustained surge handling in constrained PCB layouts.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, limiting downstream voltage to ≤53.9 V at 11.1 A. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
Designed for single-pulse and low-duty-cycle repetitive transients (0.01 % duty cycle), it supports 100 A non-repetitive forward surge current (IFSM) and withstands soldering up to 275 °C for 10 s. The device's temperature coefficient of VBR is +0.100 %/°C, enabling predictable derating above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 37.1 V / 41.0 V - defines reliable turn-on threshold range at 1.0 mA test current; ensures consistent clamping onset across production lot |
| VWM | 33.3 V - maximum continuous reverse operating voltage; sets safe margin below VBR to prevent leakage-induced heating |
| VC @ IPPM | 53.9 V at 11.1 A - clamped voltage during 10/1000 μs surge; determines worst-case stress on protected ICs |
| PPPM | 600 W - peak pulse power capability; enables robust suppression of lightning-induced or inductive-switching transients |
| IFSM | 100 A - 8.3 ms half-sine surge rating; supports protection against motor drive or relay coil energy dump |
| TJ max | +175 °C - maximum junction temperature; allows operation in under-hood automotive environments with minimal heatsinking |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; informs PCB copper area requirements for thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage 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 AEC-Q101 qualification | Surface-mount alternative with lower profile; requires rework of through-hole footprint | Select SMBJ36A for space-constrained PCBs where automated SMT assembly is preferred over axial-leaded hand-soldering. |
| 1.5KE39A | Same DO-15 package; identical VBR/VWM/VC specs; 1500 W rating (10/1000 μs); not AEC-Q101 qualified | Higher-power variant for non-automotive industrial use; lacks automotive reliability validation | Choose 1.5KE39A only for cost-sensitive commercial equipment where AEC-Q101 is not mandated and higher surge margin is required. |

FAQ
What is the meaning of the "HE3/54" suffix in P6KE39AHE3/54?
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" paper tape and reel packaging with 4000 units per reel. This distinguishes P6KE39AHE3/54 from commercial-grade P6KE39A-E3/54 variants lacking automotive qualification.
Does P6KE39AHE3/54 meet automotive reliability standards?
Yes, P6KE39AHE3/54 is explicitly AEC-Q101 qualified per Vishay documentation (Doc. 88369, Note 1), covering stress tests including high-temperature reverse bias, temperature cycling, and ESD. Its HE3 suffix confirms compliance with automotive material and process requirements defined in Vishay Doc. 99912.
What is the maximum clamping voltage of P6KE39AHE3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE39AHE3/54 is 53.9 V at 11.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across temperature and production lot, ensuring protected circuits experience no more than 53.9 V during specified transient events.
Can P6KE39AHE3/54 be used in bidirectional protection applications?
No, P6KE39AHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). For bidirectional protection, Vishay specifies part numbers ending in "CA", such as P6KE39CA. Using P6KE39AHE3/54 in bidirectional circuits would result in forward conduction during negative transients, causing failure.
How does the thermal resistance of P6KE39AHE3/54 affect PCB layout?
P6KE39AHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W. To maintain TJ ≤ 175 °C during repetitive surges, PCB copper land area must provide adequate heat sinking - minimum 100 mm² per lead recommended. Insufficient copper increases thermal impedance, risking premature thermal runaway during high-duty-cycle events.
