Product details
Overview
P6KE47C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 44.7 V to 49.4 V breakdown voltage (VBR) at 1 mA, 40.2 V stand-off 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 in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE47C-E3/73 datasheet, P6KE47C-E3/73 pinout, P6KE47C-E3/73 application, or P6KE47C-E3/73 equivalent, this page delivers verified electrical parameters, bi-directional clamping behavior, UL 497B recognition, AEC-Q101 qualification status, and thermal resistance data critical for transient protection layout and reliability validation.
Technical Context
The P6KE47C-E3/73 operates as a bi-directional avalanche diode, symmetrically clamping positive and negative transients above ±44.7 V without polarity dependence. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable breakdown under repetitive 10/1000 µs pulses at 0.01% duty cycle.
It exhibits a temperature coefficient of +0.101 %/°C for VBR, ensuring predictable voltage drift over -55 °C to +175 °C operating range. With RθJL = 20 °C/W and RθJA = 75 °C/W, thermal performance supports sustained operation at 5.0 W dissipation on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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; 45 V VWM; 69.4 V VC @ 8.6 A; same 600 W rating | Lower profile (3.5 mm height vs. DO-15's 5.8 mm); higher IPPM derating above 75 °C | Select for space-constrained layouts where leaded DO-15 mounting is impractical |
| 1.5KE47CA | DO-201AD package; identical VBR/VWM/VC; 1500 W PPPM rating | Higher surge capacity but larger footprint and 2× thermal resistance (RθJA = 150 °C/W) | Choose when legacy board design requires DO-201AD compatibility or >600 W single-pulse margin is required |
Compared with SMBJ45CA and 1.5KE47CA, the P6KE47C-E3/73 offers optimal balance of proven DO-15 manufacturability, AEC-Q101 qualification (in HE3 variant), and thermal performance for cost-sensitive automotive and industrial designs requiring standardized through-hole assembly.

FAQ
What is the polarity configuration of P6KE47C-E3/73?
The P6KE47C-E3/73 is a bi-directional TVS diode with symmetrical avalanche characteristics in both polarities. It has no cathode marking and functions identically regardless of terminal orientation - ideal for AC-coupled or differential signal lines where polarity reversal may occur. This distinguishes it from uni-directional variants like P6KE47A-E3/73, which require correct anode/cathode placement.
Does P6KE47C-E3/73 meet automotive qualification standards?
Yes - the P6KE47C-E3/73 is part of the AEC-Q101-qualified P6KE family when ordered with the HE3 suffix (e.g., P6KE47C-HE3/73). The E3 suffix indicates RoHS compliance and JESD 201 Class 1A whisker resistance, while AEC-Q101 validation covers temperature cycling, high-temperature reverse bias, and accelerated life testing required for automotive ECUs and sensors.
What is the maximum clamping voltage of P6KE47C-E3/73 under surge conditions?
The P6KE47C-E3/73 has a maximum clamping voltage (VC) of 64.8 V at 9.3 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured after full conduction and represents the upper bound of voltage seen by protected circuitry during worst-case transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
How does P6KE47C-E3/73 compare to P6KE47A-E3/73 in circuit design?
The P6KE47C-E3/73 is bi-directional, while P6KE47A-E3/73 is uni-directional. In practice, the C-version replaces two uni-directional diodes in back-to-back configuration for AC or floating lines, simplifying layout and reducing component count. However, P6KE47A-E3/73 offers lower forward voltage (3.5 V) and supports 100 A IFSM, making it preferable for DC power rail protection where polarity is fixed.
Is P6KE47C-E3/73 UL recognized for safety compliance?
Yes - the P6KE47C-E3/73 carries Underwriters Laboratories recognition under file E136766 for both uni- and bi-directional configurations, compliant with UL 497B for primary protectors in telecommunications and signal line applications. This certification validates its ability to safely fail short-circuit under overload, tripping fuses or breakers without fire hazard or smoke emission.
