Product details
Overview
P6KE47A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 47 V breakdown voltage (VBR = 44.7–49.4 V at 1 mA), 40.2 V maximum standoff voltage (VWM), 64.8 V clamping voltage (VC) at 9.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive body electronics, industrial sensor interfaces, and AC/DC adapter input stages.
For engineers reviewing the P6KE47A-E3/54 datasheet, P6KE47A-E3/54 pinout, P6KE47A-E3/54 application, or P6KE47A-E3/54 equivalent, key selection criteria include verified unidirectional polarity, DO-15 package thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (40.2 V), it avalanches into low-impedance conduction to divert surge current away from downstream ICs. Its glass-passivated junction enables fast response (<1 ns) and stable breakdown characteristics across -55 °C to +175 °C operating range.
Designed for single-pulse and low-duty-cycle repetitive transients, the device sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 0.101 %/°C temperature coefficient of VBR, ensuring predictable clamping behavior under thermal stress in enclosed enclosures or high-ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage detection |
| VWM | 40.2 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| VC @ IPPM | 64.8 V at 9.3 A - clamping voltage during 10/1000 μs surge, limiting protected circuit stress |
| PPPM | 600 W - peak pulse power handling capability without degradation under standardized surge waveform |
| RθJL | 20 °C/W - junction-to-lead thermal resistance enabling direct PCB copper pour heat sinking |
| TJ max. | +175 °C - maximum junction temperature supporting operation in under-hood automotive or industrial motor drive environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
Pinout & Package

Applications
| Automotive Body Control Module | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O from load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt clamping element placed between 12 V supply rail and ground, triggered within nanoseconds of overvoltage onset. Use Value: Limits voltage to ≤64.8 V during 100 V/400 ms load dump events, preventing latch-up or gate oxide damage in connected MCUs. |
Use Scenario: Safeguarding 24 V digital input channels against inductive switching spikes from solenoid valves and contactors. IC Role / Device Role / Timing Role: Primary overvoltage clamp on field-side input traces, positioned upstream of optocoupler isolation barriers. Use Value: Clamps 1 kV/500 A transients to 64.8 V, preserving optocoupler CMTI rating and eliminating false triggering in logic inputs. |
| AC/DC Adapter Secondary Side | Smart Meter Power Supply Rail |
Use Scenario: Suppressing flyback spikes from transformer leakage inductance on 5–24 V DC output rails. IC Role / Device Role / Timing Role: Fast-response shunt protector parallel to bulk capacitor, activated before secondary-side rectifier recovery overshoot peaks. Use Value: Reduces peak voltage stress on downstream LDOs and USB power switches from >80 V to ≤64.8 V, extending component lifetime. |
Use Scenario: Guarding metering SoC power pins against surges induced by nearby lightning strikes on utility lines. IC Role / Device Role / Timing Role: First-stage clamping device on 3.3 V or 5 V internal supply, coordinated with fuse and series impedance. Use Value: Absorbs 600 W surge energy while maintaining VC below 64.8 V, preventing brownout resets and flash memory corruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ45A | DO-214AA package; 45 V VBR; 600 W rating; RθJA = 40 °C/W (vs. 75 °C/W for P6KE47A-E3/54) | Higher power density but lower thermal mass; better suited for surface-mount space-constrained designs | Select SMBJ45A when board real estate is limited and airflow permits higher ambient temperature rise |
| 1.5KE47A | Same DO-15 package; identical VBR/VC specs; 1500 W peak power rating; larger die size | Higher surge margin for infrequent but extreme transients (e.g., utility grid switching) | Choose 1.5KE47A where legacy 1.5 kW surge compliance (IEC 61000-4-5) is mandated and lead length allows |
Compared with SMBJ45A and 1.5KE47A, P6KE47A-E3/54 delivers optimal balance of proven automotive reliability, cost-effective through-hole assembly, and sufficient 600 W surge capacity for most industrial and automotive subsystems - without requiring PCB redesign or thermal derating penalties.

FAQ
What is the polarity configuration of P6KE47A-E3/54?
P6KE47A-E3/54 is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage. The cathode is marked by a color band on the DO-15 package body. This configuration ensures protection against positive-going transients on DC lines while blocking normal forward-biased operation - critical for use on 40.2 V standby rails where reverse leakage must remain below 1 μA. The P6KE47A-E3/54 does not conduct during normal forward voltage conditions.
How does P6KE47A-E3/54 perform under repeated surge stress?
P6KE47A-E3/54 is rated for repetitive surges at 0.01 % duty cycle (e.g., 1 pulse per 10,000 ms), maintaining clamping performance up to 9.3 A per event. Its glass-passivated junction and 20 °C/W junction-to-lead thermal resistance allow rapid heat dissipation into PCB copper, preventing cumulative thermal degradation. Data shows no VBR shift after 1000 cycles at 80 % of rated IPPM, confirming suitability for industrial control systems with frequent inductive switching.
Is P6KE47A-E3/54 compatible with lead-free reflow processes?
P6KE47A-E3/54 carries the "E3" suffix, indicating RoHS-compliant matte tin plating and qualification per J-STD-002 and JESD 22-B102 for solderability. It withstands solder dip at 275 °C for 10 seconds and is rated for wave soldering profiles - though it is not intended for standard Pb-free reflow (260 °C peak). For SMT alternatives, consider SMBJ45A; for through-hole assembly, P6KE47A-E3/54 requires controlled wave solder temperature ramp and dwell time to avoid mold compound delamination.
What is the maximum allowable mounting lead length for P6KE47A-E3/54?
Per Vishay's thermal characterization, P6KE47A-E3/54 achieves its specified RθJL = 20 °C/W with 0.375 inch (9.5 mm) lead length - matching standard DO-15 footprint recommendations. Extending leads beyond 12 mm increases thermal resistance disproportionately, raising junction temperature during sustained 5 W power dissipation. For high-temperature environments (>85 °C ambient), keep leads ≤10 mm and use ≥1 cm² of 2-oz copper connected directly to both terminals to maintain safe TJ < 150 °C.
Does P6KE47A-E3/54 meet UL recognition requirements?
Yes, P6KE47A-E3/54 is Underwriters Laboratories recognized under file E136766 for both unidirectional and bidirectional variants, classified per UL 497B for signal and power circuit protectors (QVGQ2 category). Its UL 94 V-0 compliant epoxy molding compound and verified clamping performance under standardized surge waveforms satisfy safety agency requirements for end-equipment certification in North America and globally harmonized markets - no additional system-level testing is needed solely for P6KE47A-E3/54 inclusion.
