Product details
Overview
P6KE47CA-E3/54 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 47 V breakdown voltage (VBR min/max = 44.7–49.4 V at 1.0 mA), 40.2 V standoff voltage (VWM), 64.8 V maximum clamping voltage (VC) at 9.3 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 P6KE47CA-E3/54 datasheet, P6KE47CA-E3/54 pinout, P6KE47CA-E3/54 application, or P6KE47CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 leaded package compatibility, 175 °C junction temperature rating, low leakage (<1.0 μA at VWM), and AEC-Q101 qualification for automotive-grade surge protection.
Technical Context
This device operates as a voltage-clamped crowbar during transient overvoltage events, leveraging an avalanche breakdown mechanism to divert surge current away from protected circuitry. Its bidirectional symmetry enables use on AC-coupled or floating signal lines without polarity concerns, and its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surges.
The P6KE47CA-E3/54 exhibits 0.101 %/°C temperature coefficient of VBR, enabling predictable clamping behavior across -55 °C to +175 °C operating range. With 20 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient rating, it supports moderate-duty-cycle surge handling when mounted on PCBs with adequate copper area or lead heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V at 1.0 mA - defines precise avalanche onset window for repeatable clamping threshold |
| VWM | 40.2 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 64.8 V at 9.3 A - peak clamped voltage during 10/1000 μs surge, limiting stress on downstream components |
| PPPM | 600 W - peak pulse power handling capacity per single 10/1000 μs transient event |
| IPPM | 9.3 A - maximum non-repetitive surge current the device safely clamps without degradation |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-temperature industrial environments |
| Package | DO-15 (DO-204AC) - axial-leaded through-hole package with 0.242–0.258 inch body length, RoHS-compliant matte tin leads |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with axial leads; no polarity marking for bidirectional configuration - both terminals are electrically symmetric and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., inductive switch-off spikes) |
| UL 94 V-0 compliant molding | Meets flammability safety requirements for enclosed industrial and automotive enclosures |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ45CA | DO-214AA package, 45 V VWM, 64.8 V VC @ 9.2 A, same PPPM but surface-mount | Requires SMT reflow process and PCB real estate; not drop-in compatible with through-hole designs | Select SMBJ45CA only when board space constraints mandate SMT or higher mounting density is required. |
| 1.5KE47CA | Same DO-15 package, identical VBR/VWM/VC, but rated for 1500 W PPPM (10/1000 μs) | Higher surge margin for infrequent but extreme transients (e.g., direct lightning coupling); larger thermal mass | Choose 1.5KE47CA where legacy 1.5 kW surge standards apply or where long-term reliability under repeated marginal surges is critical. |
Compared with SMBJ45CA and 1.5KE47CA, the P6KE47CA-E3/54 offers optimal balance of cost, proven through-hole manufacturability, and 600 W surge capability for mid-tier industrial and automotive applications - making it preferred for designs prioritizing ease of assembly and qualification continuity over maximum power rating or miniaturization.

FAQ
What is the clamping voltage of P6KE47CA-E3/54 at its rated peak pulse current?
The P6KE47CA-E3/54 has a maximum clamping voltage (VC) of 64.8 V when subjected to its rated 9.3 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE47CA-E3/54 maintains this clamping performance across its full operating temperature range.
Is P6KE47CA-E3/54 suitable for automotive applications?
Yes, P6KE47CA-E3/54 is AEC-Q101 qualified per Vishay documentation, confirming its suitability for automotive applications including engine control modules, body electronics, and infotainment power rails. Its 175 °C maximum junction temperature, DO-15 mechanical robustness, and bidirectional clamping make it appropriate for under-hood and cabin environments. The P6KE47CA-E3/54 meets automotive surge immunity requirements when applied per recommended layout guidelines.
How does the bidirectional design of P6KE47CA-E3/54 affect its circuit placement?
The bidirectional nature of P6KE47CA-E3/54 eliminates polarity sensitivity - either lead can be connected to line or ground without affecting clamping behavior. This simplifies PCB layout and eliminates risk of incorrect orientation during manual assembly. Unlike unidirectional TVS diodes, the P6KE47CA-E3/54 provides symmetrical protection on AC-coupled signals, floating buses, or dual-rail power domains where voltage reversals may occur.
What is the standoff voltage rating for P6KE47CA-E3/54?
The standoff voltage (VWM) for P6KE47CA-E3/54 is 40.2 V - the maximum continuous DC or RMS voltage that can be applied without exceeding 1.0 μA reverse leakage current. This rating ensures reliable blocking during normal operation while allowing sufficient margin below the 44.7–49.4 V breakdown range. Designers must ensure system operating voltage remains ≤40.2 V to prevent premature conduction of the P6KE47CA-E3/54.
Does P6KE47CA-E3/54 have RoHS and REACH compliance?
Yes, P6KE47CA-E3/54 carries the "E3" suffix indicating full RoHS compliance per EU Directive 2011/65/EU and adherence to Vishay's material declaration per document 99912. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits. The P6KE47CA-E3/54 also conforms to REACH SVHC requirements and is supplied with full substance disclosure documentation upon request.
