Product details
Overview
P6KA6.8AHE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection of sensitive ICs, MOSFETs, and sensor signal lines in automotive and industrial systems. It features a 6.45 V to 7.14 V breakdown voltage (VBR), 5.80 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 57.1 V clamping voltage at 10.5 A, and AEC-Q101 qualification for automotive reliability.
For engineers reviewing the P6KA6.8AHE3/73 datasheet, P6KA6.8AHE3/73 pinout, P6KA6.8AHE3/73 application, or P6KA6.8AHE3/73 equivalent, key selection criteria include unidirectional polarity, DO-15 package compatibility, TJ = 185 °C operation, low 0.057 %/°C VBR temperature coefficient, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable clamping under repetitive transients. Its junction design supports 185 °C maximum operating temperature and meets AEC-Q101 stress test requirements including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing.
The device operates exclusively in unidirectional mode with cathode indicated by a color band. It exhibits fast response time (<1 ns), low incremental surge resistance, and excellent clamping ratio (VC/VBR ≈ 8.0), enabling robust protection against inductive switching spikes and lightning-induced surges on DC power rails and signal paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | Lower VBR (5.4–6.0 V), same DO-214AC package, 400 W PPPM | Less margin above 5 V rail; suitable only where tighter clamping is required and lower surge rating is acceptable | Select SMAJ6.0A only if board space allows SMA package and 400 W rating suffices for system-level surge test plan |
| 1.5KE6.8A | Higher PPPM (1500 W), axial DO-201AD package, VBR 6.45–7.14 V matches P6KA6.8AHE3/73 | Larger footprint and manual assembly; better for high-energy industrial mains protection | Choose 1.5KE6.8A when surge energy exceeds 600 W or axial leaded mounting is preferred for heat sinking |
Compared with SMAJ6.0A and 1.5KE6.8A, the P6KA6.8AHE3/73 delivers optimal balance of AEC-Q101 qualification, DO-15 footprint, 600 W rating, and tight VBR tolerance-making it the preferred choice for automotive and space-constrained industrial PCBs requiring production-grade reliability.

FAQ
What is the breakdown voltage range of the P6KA6.8AHE3/73?
The P6KA6.8AHE3/73 has a specified breakdown voltage (VBR) range of 6.45 V to 7.14 V at 10 mA test current, measured at TA = 25 °C. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in 5 V systems. The device maintains this specification across its full operating temperature range due to its 0.057 %/°C temperature coefficient.
Is the P6KA6.8AHE3/73 suitable for automotive applications?
Yes, the P6KA6.8AHE3/73 is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and powertrain applications. It passes high-temperature reverse bias, temperature cycling, and unbiased HAST tests per AEC-Q101 Rev G. Its DO-15 package and HE3 suffix also meet JESD201 Class 2 whisker resistance requirements for automotive PCB assembly.
What is the clamping voltage of the P6KA6.8AHE3/73 under surge conditions?
The P6KA6.8AHE3/73 clamps to a maximum of 57.1 V at its peak pulse current (IPPM) of 10.5 A, defined by the 10/1000 μs waveform. This clamping voltage is guaranteed across the full operating temperature range and forms the basis for downstream component voltage stress analysis. The low VC/VBR ratio (~8.0) reflects efficient transient energy absorption.
Does the P6KA6.8AHE3/73 have bidirectional polarity?
No, the P6KA6.8AHE3/73 is unidirectional only, with cathode identified by a color band. It conducts in forward bias like a standard diode and clamps in reverse bias above VWM. For AC or bipolar signal line protection, a separate bidirectional variant (e.g., P6SMB6.8A) or back-to-back configuration would be required-neither of which applies to the P6KA6.8AHE3/73.
What package type does the P6KA6.8AHE3/73 use?
The P6KA6.8AHE3/73 uses the DO-204AC (DO-15) package: axial-leaded, molded epoxy case with 9.5 mm body length and 3.6 mm diameter. Leads are matte tin-plated, solderable per J-STD-002 and JESD22-B102, and rated for solder dip at 275 °C for 10 seconds. The HE3 suffix confirms RoHS compliance and JESD201 Class 2 whisker resistance.
