Product details
Overview
P6KE75A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 600 W peak pulse power (10/1000 μs), 71.3–78.8 V breakdown voltage at 1 mA, 64.1 V stand-off voltage, 103 V maximum clamping voltage at 5.8 A, and operates from –55 °C to +175 °C.
For engineers reviewing the P6KE75A-E3/73 datasheet, P6KE75A-E3/73 pinout, P6KE75A-E3/73 application, or P6KE75A-E3/73 equivalent, this device is selected for robust overvoltage protection in DC power rails, automotive sensor interfaces, and industrial I/O lines where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.33), and AEC-Q101 qualification are critical.
Technical Context
The P6KE75A-E3/73 uses a glass-passivated silicon junction to achieve sub-nanosecond response time and stable clamping under repetitive surge conditions. Its unidirectional polarity enables integration into DC-biased circuits with cathode-to-rail configuration, and its 20 °C/W junction-to-lead thermal resistance supports reliable operation without heatsinking up to 5.0 W continuous dissipation at TL = 75 °C.
Designed for transient suppression per IEC 61000-4-5 (surge) and IEC 61000-4-2 (ESD), it delivers 103 V clamping at 5.8 A IPPM with <0.105 %/°C temperature coefficient of VBR - ensuring predictable voltage limiting across automotive and industrial ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 71.3–78.8 V at 1 mA - defines minimum voltage at which TVS enters avalanche conduction during overvoltage events |
| Stand-off Voltage VWM | 64.1 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| Clamping Voltage VC | 103 V at 5.8 A IPPM - limits peak voltage seen by protected circuit during 10/1000 μs surge |
| Peak Pulse Power PPPM | 600 W (10/1000 μs) - sustains high-energy transients without failure under 0.01 % duty cycle |
| Operating Temperature | –55 °C to +175 °C - supports under-hood automotive and industrial environments without derating |
| Thermal Resistance RθJL | 20 °C/W - enables efficient heat transfer from junction to lead, supporting 5.0 W PD at TL = 75 °C |
| Leakage Current ID | ≤1.0 μA at VWM - ensures minimal power loss and signal integrity in standby DC rail protection |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded, RoHS-compliant, matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band on body.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Same VBR (71.3–78.8 V) and VC (103 V), but SMC (DO-214AB) package; 600 W rating; lower RθJA (40 °C/W vs. 75 °C/W) | Suitable for surface-mount designs requiring higher power density and automated assembly; not axial-leaded | Select SMBJ75A when board space is constrained and reflow compatibility is required; P6KE75A-E3/73 preferred for through-hole prototyping or high-vibration environments. |
| 1.5KE75A | Same DO-15 package and electrical specs, but 1500 W PPPM rating; larger die size; higher VF (5.0 V) and IFSM (200 A) | Better suited for high-energy surge environments (e.g., utility meter front-end), but over-specified for typical 600 W use cases | Choose 1.5KE75A only when legacy 1.5 kW surge testing is mandated; P6KE75A-E3/73 offers optimal cost/performance balance for standard 600 W requirements. |
Compared with SMBJ75A and 1.5KE75A, the P6KE75A-E3/73 provides identical clamping performance in a cost-optimized, through-hole DO-15 package with AEC-Q101 qualification - making it ideal for automotive and industrial applications where mechanical robustness, qualification compliance, and ease of manual repair are prioritized over SMT scalability or extreme surge margin.

FAQ
What is the breakdown voltage range of the P6KE75A-E3/73?
The P6KE75A-E3/73 has a specified breakdown voltage (VBR) range of 71.3 V to 78.8 V at a test current of 1 mA. This range reflects manufacturing tolerance and ensures consistent avalanche initiation across units. The value is measured per ANSI/IEEE C62.35 and directly determines the minimum overvoltage threshold at which the P6KE75A-E3/73 begins clamping. It is validated during 100 % production testing.
Is the P6KE75A-E3/73 suitable for automotive applications?
Yes, the P6KE75A-E3/73 is AEC-Q101 qualified and rated for operating junction temperatures from –55 °C to +175 °C, making it suitable for under-hood and body-control module applications. Its glass-passivated junction, DO-15 mechanical robustness, and 600 W surge capability align with ISO 7637-2 and ISO 16750-2 requirements. The "HE3" variant is explicitly AEC-Q101 qualified, and the "E3/73" suffix indicates RoHS-compliant commercial-grade packaging with equivalent construction.
What does the "E3/73" suffix mean in P6KE75A-E3/73?
The "E3" denotes RoHS-compliant, matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "/73" refers to the specific tape-and-reel packaging option: 73 = 13-inch diameter reel, 3000 pieces per reel (standard for DO-15). This differs from "/54", which indicates 4000 pieces per reel. Both share identical electrical and thermal specifications.
How does the clamping voltage of P6KE75A-E3/73 compare to its breakdown voltage?
The P6KE75A-E3/73 clamps to a maximum of 103 V at 5.8 A peak pulse current (IPPM), yielding a clamping ratio (VC/VBR) of approximately 1.33 using the nominal VBR of 77.5 V. This ratio reflects the device's low dynamic impedance during surge conduction and is critical for determining residual voltage stress on protected ICs. The ratio remains stable across temperature due to its 0.105 %/°C VBR temperature coefficient.
Can P6KE75A-E3/73 be used in bidirectional configurations?
No - the P6KE75A-E3/73 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6KE75CA) and lack polarity marking. Using P6KE75A-E3/73 in AC or floating applications would result in forward conduction during negative half-cycles, causing failure. For bidirectional protection at 75 V standoff, P6KE75CA must be selected instead.
