Product details
Overview
P6KE7.5-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 600 W peak pulse power rating (10/1000 μs), 7.13–7.88 V breakdown voltage at 10 mA, 6.40 V maximum stand-off voltage, 11.3 V clamping voltage at 53.1 A peak pulse current, and operates across -55 °C to +175 °C junction temperature range - used in automotive ECU input protection and industrial sensor interface circuits.
For engineers reviewing the P6KE7.5-E3/73 datasheet, P6KE7.5-E3/73 pinout, P6KE7.5-E3/73 application, or P6KE7.5-E3/73 equivalent, this page delivers verified electrical parameters, thermal behavior, mechanical package data, real-world clamping performance, and direct alternative part guidance for surge protection design validation and BOM optimization.
Technical Context
The P6KE7.5-E3/73 implements a silicon avalanche diode structure with glass-passivated junction, enabling sub-nanosecond response to transient overvoltages. Its unidirectional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 50 A, supporting robust surge handling without latch-up.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), with derating starting above 25 °C ambient. The device meets AEC-Q101 qualification when ordered with HE3 suffix, but P6KE7.5-E3/73 is RoHS-compliant commercial-grade per JESD 201 Class 1A whisker test.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package; 7.0 V VWM, 11.2 V VC @ 53.5 A; 600 W rating; surface-mount | Requires SMT layout; better thermal dissipation on copper pour; not axial-leaded | Select SMBJ7.0A for space-constrained PCBs where automated assembly and higher board density are prioritized. |
| 1.5KE7.5A | DO-201AD package; same VBR range (7.13–7.88 V), identical VC (11.3 V), but larger body and 1.5 kW rating | Higher surge margin (1.5×) but 2.5× larger footprint; suited for high-energy industrial environments | Choose 1.5KE7.5A when legacy through-hole compatibility is needed alongside elevated surge endurance beyond 600 W. |
Compared with P6KE7.5-E3/73, SMBJ7.0A offers SMT efficiency and thermal advantage but requires layout change, while 1.5KE7.5A retains through-hole mounting with greater surge headroom at the cost of size - both serve distinct mechanical and reliability trade-offs in protection layer design.

FAQ
What is the maximum clamping voltage of the P6KE7.5-E3/73 under rated surge conditions?
The P6KE7.5-E3/73 has a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current of 53.1 A using the standard 10/1000 μs waveform. This value is measured per JEDEC standards and ensures predictable overvoltage limiting for downstream components. The P6KE7.5-E3/73 maintains this clamping performance across its specified operating temperature range and is validated in Vishay's characterization curves (Fig. 4).
Is the P6KE7.5-E3/73 suitable for automotive applications?
The P6KE7.5-E3/73 is RoHS-compliant commercial-grade and not AEC-Q101 qualified; however, it shares identical electrical and thermal specifications with the AEC-Q101-qualified P6KE7.5AHE3/73 variant. For non-safety-critical automotive subsystems (e.g., infotainment power rails or lighting controls), the P6KE7.5-E3/73 may be used with customer validation. The P6KE7.5-E3/73 itself does not carry AEC-Q101 certification.
How does the P6KE7.5-E3/73 differ from bi-directional TVS diodes like P6KE7.5CA?
The P6KE7.5-E3/73 is unidirectional and features a cathode band marking, intended for DC line protection where polarity is fixed. In contrast, P6KE7.5CA is bi-directional with no polarity marking and symmetric clamping in both directions - suitable for AC lines or differential signal pairs. Their VBR, VC, and PPPM values differ slightly due to structural asymmetry; the P6KE7.5-E3/73 is not interchangeable with P6KE7.5CA without circuit review.
What is the thermal resistance of the P6KE7.5-E3/73, and how does it affect PCB layout?
The P6KE7.5-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Effective heat transfer depends on lead length and copper area: keeping leads ≤9.5 mm and using ≥100 mm² copper pour per lead reduces thermal impedance. The P6KE7.5-E3/73 must be mounted with adequate clearance from heat sources to maintain TJ ≤175 °C under full-power surge duty.
Can the P6KE7.5-E3/73 replace older P6KE7.5A variants in existing designs?
Yes - the P6KE7.5-E3/73 is a direct form-fit-function replacement for legacy P6KE7.5A parts, sharing identical electrical specs, DO-204AC package dimensions, and lead finish (matte tin). The "E3" suffix confirms RoHS compliance and JESD 201 Class 1A whisker testing, making the P6KE7.5-E3/73 suitable for new designs and drop-in upgrades where environmental compliance is required.
