Product details
Overview
P6KE39CHE3/54 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 33.3 V stand-off voltage (VWM), 37.1–41.0 V breakdown voltage (VBR at 1 mA), and 53.9 V maximum clamping voltage (VC) at 11.1 A peak pulse current - deployed in automotive sensor protection and industrial I/O interfaces.
For engineers reviewing the P6KE39CHE3/54 datasheet, P6KE39CHE3/54 pinout, P6KE39CHE3/54 application, or P6KE39CHE3/54 equivalent, key selection criteria include bi-directional surge capability, AEC-Q101 qualification, RoHS-compliant HE3 whisker-tested leads, and compatibility with 10/1000 μs lightning-surge waveforms per IEC 61000-4-5.
Technical Context
This device operates as a voltage-clamping protector with symmetrical bi-directional avalanche breakdown - no polarity marking required. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 0.01% duty cycle pulses.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); derating begins above 25 °C ambient, with max operating junction temperature of +175 °C. The HE3 suffix confirms AEC-Q101 qualification 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 voltage before leakage exceeds 1 μA; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 37.1–41.0 V at 1 mA - guaranteed avalanche onset range; ensures predictable turn-on during transients |
| VC (Clamping Voltage) | 53.9 V at 11.1 A (10/1000 μs) - limits downstream voltage stress to protected ICs or MOSFETs |
| PPPM (Peak Pulse Power) | 600 W - sustains single high-energy surges per IEC 61000-4-5 Level 4 without failure |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - negligible standby power loss and minimal signal distortion in high-impedance circuits |
| TJ max. | +175 °C - supports under-hood automotive and industrial environments with extended thermal margins |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package compatible with through-hole assembly and manual rework |
Pinout & Package
DO-204AC (DO-15) molded epoxy package with matte tin-plated leads; bi-directional construction has no polarity marking - terminals are functionally identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | Either terminal serves as anode or cathode depending on transient polarity; no color band or marking required |
| Lead 1 / Lead 2 | Current path for surge conduction | Leads carry full IPPM (11.1 A) during clamping; solderable per J-STD-002; rated for 275 °C/10 s dip |
Key Features

| RoHS-compliant HE3 leads | JESD 201 Class 2 whisker resistance ensures long-term reliability in high-vibration automotive harnesses |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation meets flame-retardancy requirements for industrial control cabinets |
Applications

Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional clamping element placed across differential signal pairs or supply rails to limit voltage excursions to safe levels. Use Value: Prevents latch-up or gate oxide damage in 3.3 V/5 V interface ICs by clamping transients to ≤53.9 V while maintaining <1 μA leakage at 33.3 V nominal. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to relay coil flyback and ESD events in factory automation systems. IC Role / Device Role / Timing Role: Primary surge suppression device mounted at connector entry point, shunting energy before it reaches optocoupler or microcontroller input stages. Use Value: Enables robust operation under repeated 1 kV/500 A surge tests (IEC 61000-4-4) due to 600 W rating and low clamping ratio (VC/VBR ≈ 1.38). |
| Telecom Line Interface | Consumer Appliance Motor Control |
|
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs from lightning-induced surges on outdoor telecom wiring or building backbone cabling. IC Role / Device Role / Timing Role: Secondary-level TVS placed after gas discharge tube (GDT) primary protection to handle residual fast-rising transients. Use Value: Fast <1 ns response captures high-frequency components missed by slower GDTs, reducing risk of data corruption or PHY latch-up. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Across-motor terminals or across H-bridge freewheeling diodes to clamp inductive kickback during PWM switching. Use Value: Withstands 100 A non-repetitive forward surge (IFSM), enabling direct placement on motor drive outputs without series fusing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | DO-214AA (SMB) package; lower 600 W rating but tighter VBR tolerance (33.3–36.8 V); 55 V VC at 10.3 A | Suitable for space-constrained PCBs; requires re-layout due to SMD footprint vs. P6KE39CHE3/54's axial DO-15 | Select when board area is limited and automated SMT assembly is preferred over through-hole |
| 1.5KE39CA | Higher 1500 W PPPM rating; same DO-204AC package; VBR 37.1–41.0 V; VC 60.0 V at 25.0 A | Better suited for higher-energy surges (e.g., AC mains coupling), but larger thermal mass increases response latency | Choose when system-level testing reveals insufficient margin with 600 W rating, especially in industrial power supplies |
Compared with SMBJ33CA and 1.5KE39CA, P6KE39CHE3/54 offers optimal balance of AEC-Q101 compliance, axial through-hole manufacturability, and precise 33.3 V stand-off for 36 V nominal automotive systems - making it preferred for cost-sensitive, high-volume automotive sensor nodes where layout stability and qualification traceability are critical.

FAQ
What does the 'HE3' suffix indicate in P6KE39CHE3/54?
The HE3 suffix in P6KE39CHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance on matte tin-plated leads. This distinguishes it from commercial-grade E3 variants and confirms suitability for automotive under-hood applications where vibration, thermal cycling, and long-term reliability are critical. P6KE39CHE3/54 meets all stress test requirements defined in AEC-Q101 Rev D.
Is P6KE39CHE3/54 uni-directional or bi-directional?
P6KE39CHE3/54 is a bi-directional transient voltage suppressor, as confirmed by the 'CA' designation implied in its family naming convention (P6KE39CA) and explicit documentation stating "for bi-directional types, use CA suffix". It provides symmetrical clamping in both polarities with no cathode marking - essential for protecting AC-coupled or differential signal lines like CAN or RS-485 where voltage polarity reverses.
What is the maximum clamping voltage of P6KE39CHE3/54 under standard test conditions?
The maximum clamping voltage (VC) of P6KE39CHE3/54 is 53.9 V, measured at 11.1 A peak pulse current using the standardized 10/1000 μs waveform. This value is specified in the Electrical Characteristics table on page 2 of Vishay document 88369 and represents the upper limit of voltage imposed on protected circuitry during worst-case surge events - directly enabling safe interfacing with 3.3 V and 5 V logic systems.
Can P6KE39CHE3/54 be used in place of P6KE39A?
No - P6KE39CHE3/54 is bi-directional (functionally equivalent to P6KE39CA), whereas P6KE39A is uni-directional with a cathode band marking. Substituting them risks incorrect polarity installation and failure to suppress negative-going transients. The 'HE3' suffix also adds AEC-Q101 qualification not present in standard P6KE39A, so functional equivalence does not imply drop-in replacement without circuit review.
What is the thermal resistance from junction to lead (RθJL) for P6KE39CHE3/54?
The thermal resistance from junction to lead (RθJL) for P6KE39CHE3/54 is 20 °C/W, as specified in the Thermal Characteristics table on page 3 of Vishay document 88369. This parameter governs heat transfer efficiency during surge events and informs PCB pad design - for example, using ≥0.375" (9.5 mm) lead length and copper pour under the body improves thermal dissipation and extends surge endurance beyond single-pulse ratings.
