Product details
Overview
P6KE47-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), 40.2 V standoff voltage (VWM), 64.8 V maximum clamping voltage at 9.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection circuits.
For engineers reviewing the P6KE47-E3/54 datasheet, P6KE47-E3/54 pinout, P6KE47-E3/54 application, or P6KE47-E3/54 equivalent, key selection criteria include clamping performance under 9.3 A surge, thermal resistance (RθJL = 20 °C/W), DO-204AC package compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering bidirectional-capable surge suppression only when configured as CA variant - the P6KE47-E3/54 is unidirectional, with cathode marked by color band. Its clamping behavior is defined by low incremental surge resistance and fast sub-nanosecond response time, enabling effective suppression of ESD, lightning-induced transients, and inductive switching spikes.
Thermal design relies on lead-to-junction resistance (20 °C/W) and ambient-rated power dissipation (5.0 W at TL = 75 °C), while surge endurance follows JEDEC-standard 8.3 ms half-sine waveform testing (IFSM = 100 A). The 0.101 %/°C temperature coefficient of VBR ensures stable breakdown across –55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V - defines guaranteed avalanche initiation window under 1 mA test current |
| VWM | 40.2 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 64.8 V at 9.3 A - clamped voltage during 10/1000 µs transient, limiting downstream stress |
| PPPM | 600 W - peak transient power handling capacity per single 10/1000 µs pulse |
| IPPM | 9.3 A - maximum non-repetitive surge current supported at rated clamping voltage |
| TJ max. | +175 °C - enables operation in under-hood automotive and high-temperature industrial environments |
| RθJL | 20 °C/W - determines thermal rise from leads to junction under pulsed conduction |

| RoHS-compliant, JESD201 Class 1A whisker-tested | Ensures solder joint integrity and environmental compliance for high-reliability PCB assembly |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog output lines of engine coolant temperature sensors exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and ground to clamp negative-going transients and limit positive overshoot. Use Value: Maintains signal integrity below 64.8 V during 9.3 A surges, preventing damage to 5 V ADC input stages in vehicle ECUs. |
Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers subject to relay coil flyback and field wiring faults. IC Role / Device Role / Timing Role: Primary overvoltage clamp on channel input, positioned ahead of optocoupler or Schmitt trigger interface. Use Value: Limits transient voltage to ≤64.8 V within nanoseconds, ensuring reliable isolation barrier operation and avoiding false triggering. |
| DC Power Rail Protection | Consumer Device USB Port Protection |
Use Scenario: Secondary protection on 48 V telecom power supply outputs where upstream MOVs handle bulk energy but require precise clamping. IC Role / Device Role / Timing Role: Fast-response secondary suppressor parallel to load, activated after MOV voltage overshoot. Use Value: Clamps residual overshoot to 64.8 V with <1 ns response, protecting PoE-powered Ethernet switches and base station RF modules. |
Use Scenario: Overvoltage guard on VBUS line of USB 2.0 ports in smart home hubs vulnerable to hot-plug transients and ESD. IC Role / Device Role / Timing Role: Unidirectional shunt device between VBUS and ground, triggered only during overvoltage events above 40.2 V. Use Value: Prevents latch-up in USB controller ICs by limiting VBUS to 64.8 V during ±15 kV contact ESD per IEC 61000-4-2. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ45A | DO-214AA package (smaller footprint), 45 V VWM, 64.8 V VC @ 9.2 A, same 600 W rating | Preferred for space-constrained PCBs; lower thermal resistance (RθJA = 40 °C/W vs. 75 °C/W) but requires re-layout | Select SMBJ45A when board area is limited and lead-to-board thermal path is optimized. |
| P6KE47CA | Bi-directional variant (no polarity marking), identical VBR/VC specs, same DO-204AC package | Required for AC-coupled or bidirectional signal lines (e.g., RS-485, CAN bus) where reverse polarity transients occur | Choose P6KE47CA only when protecting symmetrical differential interfaces without DC bias. |
Compared with P6KE47-E3/54, SMBJ45A offers smaller footprint and better board-level thermal performance but demands layout revision, while P6KE47CA provides identical surge capability with bidirectional clamping - essential for differential data lines but unnecessary for unidirectional DC rails.

FAQ
What is the breakdown voltage tolerance for P6KE47-E3/54?
The P6KE47-E3/54 has a specified breakdown voltage range of 44.7 V to 49.4 V at 1 mA test current (VBR min/max), corresponding to a ±5% tolerance around the nominal 47 V rating. This ensures consistent avalanche initiation across production lots while allowing margin for thermal drift and manufacturing variation - critical for predictable clamping behavior in P6KE47-E3/54-based protection circuits.
Is P6KE47-E3/54 suitable for automotive applications?
Yes, P6KE47-E3/54 is AEC-Q101 qualified and manufactured with JESD201 Class 1A whisker-tested leads, making it suitable for automotive applications including engine control units, body electronics, and sensor front-ends. Its –55 °C to +175 °C operating range, glass-passivated junction, and DO-204AC mechanical robustness meet automotive environmental and reliability requirements - confirmed in the official Vishay documentation for P6KE47-E3/54.
What does the "E3/54" suffix mean in P6KE47-E3/54?
The "E3" denotes RoHS-compliant, commercial-grade construction with JESD201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery containing 4000 units. This ordering format aligns with Vishay's standard logistics coding - the full designation P6KE47-E3/54 uniquely identifies the RoHS-compliant, tape-and-reel packaged version of the P6KE47A TVS diode.
How does P6KE47-E3/54 compare to P6KE47CA?
P6KE47-E3/54 is unidirectional with cathode marking, while P6KE47CA is bi-directional (no polarity mark) and rated for symmetric clamping in both directions. Both share identical VBR, VC, and PPPM values, but P6KE47CA is required for AC signals or differential buses like RS-485. The P6KE47-E3/54 remains optimal for DC power rails and unidirectional analog/sensor lines where reverse conduction must be blocked.
What is the maximum clamping voltage of P6KE47-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE47-E3/54 is 64.8 V at 9.3 A peak pulse current with a 10/1000 µs waveform. This value represents the upper limit of voltage seen by downstream circuitry during worst-case transient events - a key parameter used to verify safe operation margins for 48 V systems and 5 V logic interfaces protected by P6KE47-E3/54.
