Product details
Overview
P6KE7.5HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), 11.3 V maximum clamping voltage (VC) at 53.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECU input protection and industrial sensor interface circuits.
For engineers reviewing the P6KE7.5HE3/73 datasheet, P6KE7.5HE3/73 pinout, P6KE7.5HE3/73 application, or P6KE7.5HE3/73 equivalent, this AEC-Q101-qualified DO-15 device delivers verified clamping performance, low leakage (<500 µA at VWM), and robust surge immunity for designs requiring IEC 61000-4-5 Level 3 compliance and long-term reliability under repetitive transients.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VBR (7.13–7.88 V), it avalanches into low-impedance conduction to divert surge energy away from downstream ICs. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
Thermal design is enabled by RθJL = 20 °C/W and TJ(max) = 175 °C, allowing sustained operation under pulsed loads up to 100 A (8.3 ms half-sine). The HE3 suffix confirms AEC-Q101 qualification, matte tin plating per J-STD-002, and JESD 201 Class 2 whisker resistance - essential for automotive under-hood applications.

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, 10.5 V VC @ 56.7 A; same 600 W rating but higher IPPM | Surface-mount alternative for space-constrained PCBs; requires rework of footprint and thermal relief pads | Select SMBJ7.0A when board real estate is limited and wave-solder compatibility is not required. |
| 1.5KE7.5A | DO-201AD package; identical VWM/VBR/VC specs but 1.5 kW rating; larger body (5.6 mm Ø × 9.5 mm) | Higher-power replacement for legacy designs needing >600 W headroom; heavier thermal mass delays thermal runaway | Choose 1.5KE7.5A only if system-level surge testing exceeds 600 W or if existing layout accommodates larger DO-201AD footprint. |
Compared with SMBJ7.0A and 1.5KE7.5A, the P6KE7.5HE3/73 uniquely balances AEC-Q101 qualification, DO-15 through-hole manufacturability, and precise 6.4 V standoff for 5 V rail protection - making it optimal for cost-sensitive, high-reliability automotive and industrial assemblies where leaded assembly remains standard.

FAQ
What is the maximum clamping voltage of the P6KE7.5HE3/73 under rated surge conditions?
The P6KE7.5HE3/73 has a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current of 53.1 A using a 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees that downstream components see no more than 11.3 V during transient events - critical for safeguarding 3.3 V and 5 V logic interfaces. The P6KE7.5HE3/73 maintains this clamping performance across its full operating temperature range (–55 °C to +175 °C).
Is the P6KE7.5HE3/73 suitable for automotive applications?
Yes, the P6KE7.5HE3/73 is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body control modules, and infotainment power supplies. Its HE3 suffix denotes compliance with JESD 201 Class 2 whisker resistance, matte tin plating per J-STD-002, and validation across temperature cycling, mechanical shock, and humidity tests. The P6KE7.5HE3/73 meets ISO 16750-2 load dump requirements when properly mounted with adequate copper pour for thermal dissipation.
How does the P6KE7.5HE3/73 differ from the standard P6KE7.5A variant?
The P6KE7.5HE3/73 differs from the commercial-grade P6KE7.5A by its AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and enhanced process controls for automotive reliability. While both share identical electrical specs (VWM = 6.40 V, VBR = 7.13–7.88 V, VC = 11.3 V), the HE3/73 variant undergoes additional screening including high-temperature operating life (HTOL) and unbiased highly accelerated stress test (uHAST). The P6KE7.5HE3/73 is designated for automotive Tier 1 suppliers and industrial applications demanding extended lifetime and zero-defect quality.
What is the standoff voltage (VWM) of the P6KE7.5HE3/73, and why is it important?
The standoff voltage (VWM) of the P6KE7.5HE3/73 is 6.40 V - the maximum DC or continuous reverse voltage the device can withstand without exceeding 500 µA leakage current. This parameter defines the safe operating margin below the breakdown threshold and ensures the P6KE7.5HE3/73 remains non-conductive during normal operation of 5 V systems. Selecting a VWM ≥10–20% above nominal rail voltage prevents false triggering while maintaining sufficient headroom for ripple and tolerance stack-up.
Can the P6KE7.5HE3/73 be used in bi-directional protection configurations?
No, the P6KE7.5HE3/73 is a unidirectional TVS diode and is not rated for bi-directional operation. Its electrical characteristics - including VBR, VC, and leakage - apply only in reverse bias; forward conduction follows standard silicon diode behavior (VF ≈ 3.5 V at 50 A). For bi-directional protection, Vishay specifies CA-suffix variants such as P6KE7.5CA. Using the P6KE7.5HE3/73 in AC-coupled or floating signal lines without proper polarity awareness may result in unintended forward conduction or inadequate clamping.
