Product details
Overview
P6KE39CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 39 V breakdown voltage (VBR min/max = 37.1–41.0 V), 33.3 V standoff voltage (VWM), 53.9 V maximum clamping voltage at 11.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE39CAHE3/54 datasheet, P6KE39CAHE3/54 pinout, P6KE39CAHE3/54 application, or P6KE39CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (33.3 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity marking requirements.
Designed for repetitive 10/1000 µs surges at ≤0.01 % duty cycle, it sustains 600 W peak pulse power while maintaining clamping voltage ≤53.9 V at 11.1 A. Thermal performance is characterized by RθJL = 20 °C/W and RθJA = 75 °C/W, enabling reliable operation up to TJ = +175 °C with proper lead heat sinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 37.1 V / 41.0 V - defines guaranteed avalanche onset range under 1.0 mA test current |
| VWM | 33.3 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 53.9 V at 11.1 A - maximum clamped voltage during 10/1000 µs surge, limiting stress on protected ICs |
| PPPM | 600 W - peak transient power handling capacity, derated above 25 °C per Fig. 2 |
| IPPM | 11.1 A - peak surge current supported with 10/1000 µs waveform at TA = 25 °C |
| TJ max | +175 °C - maximum junction temperature, supporting under-hood automotive use with proper PCB thermal design |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for calculating safe power dissipation in lead-mounted layouts |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional functionality confirmed by CA suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Both terminals function identically - no cathode band; device conducts equally in either direction upon overvoltage |
| Lead 1 / Lead 2 | Current path to PCB copper | Leads serve as primary thermal conduction path to board; RθJL = 20 °C/W assumes 0.375" (9.5 mm) lead length |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade temperature cycling, humidity, and mechanical shock per JESD22 standards |
| 600 W peak pulse power (10/1000 µs) | Provides robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surge events |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage exposure to protected components during transient suppression |
| UL 497B recognized (QVGQ2 file E136766) | Meets safety standard for telecom and industrial signal line protectors without additional certification overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | DO-214AA package, 36 V VWM, 58.1 V VC @ 10.3 A, same 600 W rating but lower clamping voltage margin | Suitable for space-constrained SMT layouts; lacks AEC-Q101 qualification in standard grade | Select when PCB real estate favors SMT and automotive qualification is not required |
| 1.5KE39CA | Same DO-15 package, identical VWM/VBR/VC specs, but commercial-grade (E3 suffix only), not AEC-Q101 qualified | Acceptable for non-automotive industrial or consumer use where extended temperature validation is unnecessary | Choose for cost-sensitive applications where AEC-Q101 is not mandated |
Compared with SMBJ36CA and 1.5KE39CA, P6KE39CAHE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole mechanical robustness, and UL 497B recognition - making it the preferred choice for automotive power distribution and industrial control modules requiring certified reliability and legacy-compatible mounting.

FAQ
What does the 'CA' suffix indicate in P6KE39CAHE3/54?
The 'CA' suffix denotes bidirectional configuration: P6KE39CAHE3/54 provides symmetrical clamping for both positive and negative voltage transients, with no polarity marking required. This distinguishes it from unidirectional variants (e.g., P6KE39A) that feature a cathode band and conduct only in reverse bias. The CA version is essential for AC-coupled or differential signal protection where polarity reversal occurs.
Is P6KE39CAHE3/54 qualified for automotive applications?
Yes, P6KE39CAHE3/54 carries the HE3 suffix, confirming AEC-Q101 qualification per Vishay's documentation. This includes stress testing for temperature cycling, humidity, mechanical shock, and surge robustness - validating its suitability for under-hood and chassis-mounted automotive electronics where reliability under thermal and electrical stress is critical.
What is the maximum clamping voltage of P6KE39CAHE3/54 and at what current is it specified?
The maximum clamping voltage (VC) of P6KE39CAHE3/54 is 53.9 V, measured at 11.1 A peak pulse current (IPPM) using the standardized 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge conditions and is critical for ensuring downstream components remain within their absolute maximum ratings.
How does the HE3 suffix differ from E3 in P6KE39CAHE3/54?
The HE3 suffix in P6KE39CAHE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification, whereas E3 denotes RoHS compliance only for commercial-grade parts. HE3 devices undergo additional automotive-specific qualification tests including extended temperature cycling and accelerated life testing - making P6KE39CAHE3/54 appropriate for automotive Tier 1 suppliers and industrial applications requiring validated long-term reliability.
Can P6KE39CAHE3/54 be used in place of P6KE39CA-E3/54?
No - P6KE39CAHE3/54 and P6KE39CA-E3/54 are not interchangeable without design review. While both share identical electrical specs and DO-15 packaging, the HE3 variant is AEC-Q101 qualified and tested to automotive reliability standards, whereas the E3 version is commercial grade. Substituting E3 for HE3 in automotive or mission-critical industrial designs risks non-compliance with functional safety or qualification requirements.
