Product details
Overview
P6KE39HE3/54 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 sensitive electronics. It features a 33.3 V stand-off voltage (VWM), 37.1–41.0 V breakdown voltage (VBR) at 1.0 mA, 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 - deployed in automotive sensor signal lines, industrial I/O ports, and DC power rail surge suppression.
For engineers reviewing the P6KE39HE3/54 datasheet, P6KE39HE3/54 pinout, P6KE39HE3/54 application, or P6KE39HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, 1.0 μA reverse leakage at VWM, low thermal resistance (20 °C/W junction-to-lead), and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability standards.
Technical Context
The P6KE39HE3/54 operates as a uni-directional avalanche-clamping device, triggered when transient voltage exceeds its 37.1–41.0 V breakdown range. Its glass-passivated junction enables sub-nanosecond response to ESD and lightning-induced surges, with clamping action limiting downstream voltage to ≤53.9 V at 11.1 A IPPM under standardized 10/1000 μs pulses.
Thermally, it sustains 5.0 W steady-state dissipation on infinite heatsink at TL = 75 °C and handles 100 A non-repetitive forward surge (8.3 ms half-sine). Its 20 °C/W RθJL supports reliable heat transfer through leads, while the DO-204AC case meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 33.3 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 37.1–41.0 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 53.9 V at 11.1 A IPPM - Peak voltage seen by protected circuit under worst-case 10/1000 μs surge; determines IC survivability. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per transient event; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IPPM (Peak Pulse Current) | 11.1 A - Maximum surge current handled at rated clamping voltage; sets minimum series impedance for effective protection. |
| TJ max. | 175 °C - Maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial environments. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; supports direct PCB trace heat sinking without external heatsink. |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; cathode indicated by color band on body; compliant with UL 94 V-0 and JESD 22-B106 (275 °C, 10 s solder dip).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to lower-potential side (e.g., GND or return line); conducts during positive transients in uni-directional configuration. |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 24 V rail or sensor output); avalanches into conduction when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - suitable for engine control, ADAS, and body electronics. |
| Glass passivated junction | Enables stable, repeatable avalanche characteristics over lifetime and across temperature; eliminates surface leakage paths that degrade clamping consistency. |
| 600 W peak pulse power (10/1000 μs) | Provides immunity to high-energy transients from inductive load switching (e.g., solenoid drivers, relay coils) without degradation after repeated events. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on downstream ICs - critical for protecting 3.3 V or 5 V logic interfaces exposed to 24 V system surges. |
| RoHS-compliant, JESD 201 Class 2 whisker resistant | Ensures long-term solder joint integrity in high-reliability applications; eliminates risk of tin whisker growth causing latent shorts in sealed enclosures. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33A-E3/52 | DO-214AA package; 33 V VWM; 53.3 V VC at 11.8 A; 600 W rating; same AEC-Q101 qualification. | Surface-mount footprint reduces board space vs. through-hole DO-15; better suited for high-density PCB layouts. | Select SMBJ33A-E3/52 when automated SMT assembly, smaller form factor, or improved thermal performance via pad copper area is prioritized. |
| 1.5KE33A | Same DO-204AC package; 33 V VWM; 53.3 V VC at 11.3 A; 1500 W PPPM; commercial grade only (not AEC-Q101 qualified). | Higher surge rating suits infrequent but extreme transients (e.g., utility grid coupling); lacks automotive qualification and whisker resistance. | Choose 1.5KE33A only for cost-sensitive industrial applications where AEC-Q101 and JESD 201 Class 2 are not required. |
Compared with SMBJ33A-E3/52, P6KE39HE3/54 offers through-hole mechanical robustness and legacy design compatibility; versus 1.5KE33A, it trades peak power for automotive-grade reliability and tighter parametric control - making it optimal for production automotive and high-assurance industrial systems.

FAQ
What is the clamping voltage of the P6KE39HE3/54 under standard test conditions?
The P6KE39HE3/54 has a maximum clamping voltage (VC) of 53.9 V at 11.1 A peak pulse current (IPPM) using the 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings. The P6KE39HE3/54 maintains this clamping performance across its specified operating temperature range.
Is the P6KE39HE3/54 suitable for automotive applications?
Yes, the P6KE39HE3/54 is AEC-Q101 qualified and carries the HE3 suffix denoting automotive-grade construction, including JESD 201 Class 2 whisker resistance and extended temperature operation up to 175 °C. It is explicitly intended for use in automotive subsystems such as body control modules, sensor interfaces, and infotainment power supplies - validated for thermal cycling, humidity bias, and mechanical shock per AEC-Q101 requirements.
How does the P6KE39HE3/54 differ from the commercial-grade P6KE39A-E3/54?
The P6KE39HE3/54 differs from P6KE39A-E3/54 primarily in qualification and process control: HE3 denotes AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and tighter lot-to-lot parametric consistency for automotive use, whereas the E3 suffix alone indicates RoHS-compliant commercial grade only. Both share identical electrical specs (VWM = 33.3 V, VC = 53.9 V), DO-204AC package, and 600 W rating - but only P6KE39HE3/54 is approved for production automotive designs.
What is the reverse leakage current of the P6KE39HE3/54 at its stand-off voltage?
The P6KE39HE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its stand-off voltage (VWM) of 33.3 V and ambient temperature of 25 °C. This ultra-low leakage ensures negligible power loss and no measurable loading effect on high-impedance signal paths - essential for precision analog sensor interfaces and battery-powered systems where standby current must be minimized.
Can the P6KE39HE3/54 be used in bi-directional protection configurations?
No, the P6KE39HE3/54 is a uni-directional TVS diode, identified by the "A" suffix and cathode band marking. Bi-directional variants require the "CA" suffix (e.g., P6KE39CA). Using P6KE39HE3/54 in bi-directional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. For symmetric surge suppression, select a verified bi-directional part like P6KE39CA or SMBJ33CA.
