Product details
Overview
P4KE62-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 53.0 V stand-off voltage (VWM), 58.9–65.1 V breakdown range (VBR at 1.0 mA), 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P4KE62-E3/73 datasheet, P4KE62-E3/73 pinout, P4KE62-E3/73 application, or P4KE62-E3/73 equivalent, key selection criteria include its unidirectional polarity, glass-passivated junction, AEC-Q101 qualification (via HE3 variant), 175 °C max junction temperature, and DO-41 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated chip junction ensures stable leakage performance and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
The device is rated for 400 W peak pulse power under 10/1000 μs waveform with 0.01% duty cycle, and supports 40 A non-repetitive forward surge current (8.3 ms half-sine). Thermal resistance is 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient), confirming suitability for lead-soldered mounting without heatsinking in moderate-power applications.
Key Specifications

FAQ
What is the maximum clamping voltage of the P4KE62-E3/73 under standard test conditions?
The P4KE62-E3/73 has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) using the 10/1000 μs waveform. This value is measured per JEDEC standards and reflects the highest voltage the protected circuit will experience during a defined transient event. The clamping performance is guaranteed across the full operating temperature range and directly impacts the survivability of downstream components like MOSFETs or regulators.
Is the P4KE62-E3/73 suitable for automotive applications requiring AEC-Q101 qualification?
The P4KE62-E3/73 itself is the commercial-grade version (E3 suffix), but Vishay offers the functionally identical P4KE62HE3/73 variant with full AEC-Q101 qualification. Both share the same die, electrical specs, and DO-41 package; only the test documentation and screening differ. For automotive designs, P4KE62HE3/73 must be specified - P4KE62-E3/73 meets all electrical and mechanical requirements but lacks the required stress-test certification.
How does the P4KE62-E3/73 compare to the 1.5KE62A in terms of clamping performance and physical compatibility?
The P4KE62-E3/73 clamps at 85.0 V versus 100 V for the 1.5KE62A under comparable test conditions - a 15 V advantage critical for protecting 60 V-rated components. Both use DO-41 packages and are physically interchangeable on PCBs, but the 1.5KE62A draws more surge current (4.0 A vs. 4.7 A) at higher clamping voltage and dissipates significantly more heat due to its 1500 W rating. P4KE62-E3/73 is preferred where tighter voltage control and lower thermal stress are priorities.
What is the reverse leakage current specification for the P4KE62-E3/73 at its stand-off voltage?
The P4KE62-E3/73 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 53.0 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage ensures negligible power loss in always-on circuits and avoids loading high-impedance sensor nodes or precision voltage references. Leakage remains below 5 μA up to 125 °C, supporting stable operation in demanding thermal environments.
Can the P4KE62-E3/73 be used in bidirectional configurations?
No - the P4KE62-E3/73 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., P4KE62CA), which has symmetrical breakdown in both polarities and no polarity marking. Using P4KE62-E3/73 in reverse-biased AC applications would result in forward conduction and failure; always verify polarity alignment in schematic and layout for P4KE62-E3/73.
