Product details
Overview
P6KE8.2CA-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 600 W peak pulse power (10/1000 μs), 7.79–8.61 V breakdown voltage at 10 mA, 7.02 V stand-off voltage, 200 μA max reverse leakage, and clamps to ≤12.1 V at 49.6 A peak pulse current.
For engineers reviewing the P6KE8.2CA-E3/54 datasheet, P6KE8.2CA-E3/54 pinout, P6KE8.2CA-E3/54 application, or P6KE8.2CA-E3/54 equivalent, this device serves as a robust, AEC-Q101-qualified (HE3 variant) overvoltage protection component for automotive sensor interfaces, industrial I/O lines, and consumer power supply rails where fast response (<1 ns), low clamping ratio, and bidirectional surge immunity are required.
Technical Context
The P6KE8.2CA-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities. Its bidirectional architecture eliminates polarity concerns in AC-coupled or floating signal paths, and its 12.1 V clamping voltage at 49.6 A ensures predictable voltage limiting during ESD or inductive switching events.
Thermal performance is defined by 20 °C/W junction-to-lead resistance and 75 °C/W junction-to-ambient resistance, supporting operation from –55 °C to +175 °C. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker resistance (E3 suffix), confirming suitability for automated assembly and long-term reliability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | Surface-mount SMB package; 8.0 V nominal VWM; same 600 W PPPM but lower 11.2 V clamping at 53.5 A | Requires SMT layout; better for space-constrained designs but lacks axial lead mechanical robustness | Select when board real estate is limited and reflow assembly is used; verify thermal pad design for 20 °C/W RθJA |
| 1.5KE8.2CA | Same DO-15 package; higher 1500 W PPPM; 7.79–8.61 V VBR; clamps to 13.4 V at 112 A | Over-specified for 600 W needs; larger junction capacitance may affect high-speed signal lines | Choose only if legacy 1.5KE footprint compatibility is required or system demands >1 kA surge handling |
Compared with SMBJ8.0CA and 1.5KE8.2CA, the P6KE8.2CA-E3/54 offers optimal balance of axial-mount ruggedness, cost-effective 600 W rating, and tight 12.1 V clamping-making it ideal for mid-tier industrial and automotive applications where DO-15 form factor and JEDEC-compliant lead finish are mandatory.

FAQ
What is the breakdown voltage range of the P6KE8.2CA-E3/54?
The P6KE8.2CA-E3/54 has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at a test current of 10 mA, measured per ANSI/IEEE C62.35 standards. This range ensures consistent avalanche initiation across production lots and temperature extremes, directly enabling precise overvoltage threshold setting in protection circuits using the P6KE8.2CA-E3/54.
Does the P6KE8.2CA-E3/54 have polarity markings?
No, the P6KE8.2CA-E3/54 does not have polarity markings because it is a bidirectional TVS diode. Its DO-15 package has identical electrical behavior at both leads, allowing unrestricted orientation during PCB assembly. This symmetry simplifies layout and eliminates risk of reverse installation - a key advantage over unidirectional variants like P6KE8.2A, which feature a cathode band.
What is the maximum clamping voltage of the P6KE8.2CA-E3/54 under surge conditions?
The P6KE8.2CA-E3/54 clamps to a maximum of 12.1 V when subjected to its rated peak pulse current of 49.6 A (10/1000 μs waveform). This clamping voltage is measured at the device terminals and represents the upper limit of voltage imposed on protected circuitry during worst-case transients, ensuring downstream 5 V or 3.3 V ICs remain within safe operating limits when using the P6KE8.2CA-E3/54.
Is the P6KE8.2CA-E3/54 suitable for automotive applications?
Yes - the P6KE8.2CA-E3/54 is RoHS-compliant and offered in an AEC-Q101-qualified variant (P6KE8.2CAHE3/54). While the E3 suffix denotes commercial-grade qualification, the HE3 suffix confirms full AEC-Q101 compliance including temperature cycling, high-temperature reverse bias, and accelerated life testing. For automotive use, specify P6KE8.2CAHE3/54 to ensure qualification for under-hood and ECU environments.
How does the P6KE8.2CA-E3/54 compare to the P6KE8.2A in terms of functionality?
The P6KE8.2CA-E3/54 is bidirectional, whereas the P6KE8.2A is unidirectional. This means the P6KE8.2CA-E3/54 suppresses transients of either polarity symmetrically - ideal for AC signals, floating buses, or differential lines - while the P6KE8.2A only protects against reverse-polarity surges and requires correct cathode orientation. Both share identical VBR, VWM, and PPPM ratings, but the CA version eliminates polarity dependency in the P6KE8.2CA-E3/54 design.
