Product details
Overview
P6KE47C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 47 V breakdown voltage (VBR = 44.7–49.4 V at IT = 1.0 mA), 64.8 V maximum clamping voltage at 9.3 A peak pulse current (10/1000 µs), 600 W peak pulse power rating, and DO-204AC (DO-15) package. It is used to protect MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD in automotive and industrial control systems.
For engineers reviewing the P6KE47C-E3/54 datasheet, P6KE47C-E3/54 pinout, P6KE47C-E3/54 application, or P6KE47C-E3/54 equivalent, key selection criteria include bi-directional clamping capability, low thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification (via HE3 variant), RoHS-compliant matte tin plating, and UL 94 V-0 molded epoxy housing - all critical for reliability in harsh-environment transient suppression.
Technical Context
The P6KE47C-E3/54 operates as a voltage-clamped avalanche diode with symmetrical bi-directional conduction - no polarity marking required. Its glass-passivated junction enables sub-nanosecond response to transients, while its 10/1000 µs waveform-rated 600 W surge capability supports repetitive 0.01% duty cycle pulses without degradation.
Clamping performance is defined by VC = 64.8 V at IPPM = 9.3 A, with low incremental surge resistance ensuring minimal voltage overshoot during fast-rising surges. Thermal design relies on RθJL = 20 °C/W to maintain TJ ≤ 175 °C under sustained surge conditions, validated per JESD 22-B106 solder dip (275 °C, 10 s).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V at IT = 1.0 mA - defines precise avalanche onset threshold for bi-directional clamping |
| VWM | 40.2 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 64.8 V at 9.3 A (10/1000 µs) - limits protected circuit voltage during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capacity without failure |
| RθJL | 20 °C/W - enables efficient heat transfer from junction to lead for PCB trace thermal management |
| TJ max. | 175 °C - supports operation in under-hood automotive and high-ambient industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with UL 94 V-0 epoxy molding |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with glass-passivated chip; no polarity marking (bi-directional); matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | No functional distinction - either lead serves as input/output terminal for transient clamping in both polarities |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 600 W peak pulse power (10/1000 µs) | Withstands high-energy transients from relay coil decay or motor commutation without degradation |
| AEC-Q101 qualified (HE3 variant) | Validated for automotive electronics per stress test requirements including temperature cycling and HTRB |
| UL 94 V-0 flammability rating | Mold compound self-extinguishes under flame exposure - meets safety-critical system requirements |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage stress on downstream components during surge events |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Suppressing load-dump spikes (up to 120 V) on 12 V battery-fed ECUs and body control modules. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of LDO regulators and CAN transceivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ45CA | DO-214AA package; lower 45 V standoff (VWM = 45 V); same 600 W rating but higher IPPM (13.3 A) | Better suited for space-constrained PCBs; requires re-layout due to SMD footprint | Select when board area is limited and surface-mount assembly is preferred over through-hole |
| 1.5KE47CA | Same DO-204AC package; higher 1500 W peak power; larger 1.5 kW package size and weight | Used where legacy 1.5 kW surge immunity (IEC 61000-4-5 Level 4) is mandated | Choose only if system-level surge testing requires >600 W margin - otherwise P6KE47C-E3/54 offers optimal cost/size balance |
Compared with SMBJ45CA and 1.5KE47CA, the P6KE47C-E3/54 delivers identical bi-directional clamping performance in a proven through-hole package with lower unit cost and AEC-Q101 availability via HE3 variant - making it ideal for cost-sensitive, high-reliability industrial and automotive designs requiring validated surge immunity.

FAQ
What does the "C" suffix indicate in P6KE47C-E3/54?
The "C" in P6KE47C-E3/54 denotes bi-directional configuration - meaning the device provides symmetrical clamping for both positive and negative transients without polarity sensitivity. Unlike uni-directional variants (e.g., P6KE47A), the P6KE47C-E3/54 has no cathode band marking and functions identically regardless of terminal orientation in-circuit. This makes P6KE47C-E3/54 ideal for AC signal lines, transformer-coupled interfaces, and floating bus protection where voltage polarity reversal occurs.
Is P6KE47C-E3/54 RoHS compliant and halogen-free?
Yes, P6KE47C-E3/54 is RoHS compliant per Directive 2011/65/EU, with matte tin-plated leads and UL 94 V-0 epoxy molding compound. While Vishay documents halogen-free compliance per JEDEC JS709A for select part numbers, the P6KE47C-E3/54 datasheet does not explicitly state halogen-free status - therefore, halogen content should be verified directly with Vishay for mission-critical applications. The E3 suffix confirms JESD 201 Class 1A whisker resistance.
How does P6KE47C-E3/54 differ from the HE3 variant?
The P6KE47C-E3/54 is the commercial-grade version, while P6KE47C-HE3/54 is AEC-Q101 qualified for automotive use. Both share identical electrical specs (VBR, VC, PPPM) and DO-204AC packaging, but the HE3 variant undergoes additional stress testing - including temperature cycling, high-temperature reverse bias, and accelerated life testing - to ensure reliability in automotive under-hood environments. For non-automotive industrial applications, P6KE47C-E3/54 remains fully suitable and more cost-effective.
What is the maximum allowable lead temperature during soldering for P6KE47C-E3/54?
The maximum solder dip temperature for P6KE47C-E3/54 is 275 °C for up to 10 seconds, per JESD 22-B106. This specification ensures the glass-passivated junction and epoxy mold remain intact during wave or hand-soldering processes. Exceeding this limit risks delamination or junction degradation. For reflow, Vishay recommends profile adherence to J-STD-020, though P6KE47C-E3/54 is primarily intended for through-hole assembly.
Can P6KE47C-E3/54 replace P6KE47A in an existing design?
No - P6KE47C-E3/54 and P6KE47A are not interchangeable without circuit review. P6KE47A is uni-directional (cathode-banded), while P6KE47C-E3/54 is bi-directional (no band). Substituting P6KE47C-E3/54 for P6KE47A in a DC-biased line may cause unintended conduction or failed clamping. Only use P6KE47C-E3/54 where the protected node is truly AC-coupled or floating. Always verify layout, grounding, and bias conditions before replacement.
