Product details
Overview
P4KE13HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level ESD and surge protection. It features a 12.4 V minimum breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage (VC) at 22.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and I/O lines of automotive sensor modules.
For engineers reviewing the P4KE13HE3/73 datasheet, P4KE13HE3/73 pinout, P4KE13HE3/73 application, or P4KE13HE3/73 equivalent, this AEC-Q101 qualified TVS offers validated transient suppression for 12 V automotive systems, low-leakage operation (<1.0 μA at VWM), and robust thermal performance up to 175 °C junction temperature.
Technical Context
This unidirectional TVS operates by avalanche breakdown above its VBR threshold (12.4–13.7 V), clamping transients to ≤18.2 V while sustaining 400 W peak pulse power. Its glass-passivated junction ensures stable leakage (<1.0 μA at 11.1 V) and fast response time (<1.0 ns), critical for protecting MOSFET gates and microcontroller I/O pins.
Thermal design is supported by RθJL = 66 °C/W and RθJA = 100 °C/W (LLead = 10 mm), enabling reliable operation under repetitive surge conditions up to 0.01% duty cycle. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - defines precise avalanche initiation range for repeatable clamping behavior |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 18.2 V at 22.0 A - clamped voltage during 10/1000 μs surge, limiting stress on downstream ICs |
| PPPM | 400 W - peak transient energy absorption capability per single pulse, compliant with ISO 7637-2 Pulse 1/2a/5a |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | DO-214AC (SMA) package; 13.3 V VBR min; 200 W PPPM; 17.0 V VC at 11.7 A | Lower power rating and surface-mount form factor - suited for space-constrained PCBs but not direct replacement for through-hole DO-41 layouts | Select when board real estate is limited and surge energy does not exceed 200 W; requires layout revision |
| 1.5KE13A | DO-201AD package; identical VBR/VC specs; 1500 W PPPM; higher IPPM (109 A) | Higher surge capacity supports heavy-duty industrial environments but larger footprint and higher cost | Choose for enhanced ruggedness in generator-powered equipment or where ISO 7637-2 Pulse 5b compliance is required |
Compared with SMAJ13A and 1.5KE13A, the P4KE13HE3/73 delivers optimal balance of AEC-Q101 qualification, 400 W surge handling, and DO-41 through-hole compatibility - making it the preferred choice for cost-sensitive, high-volume automotive and industrial power rail protection where proven reliability and legacy board support are essential.

FAQ
What is the breakdown voltage range for P4KE13HE3/73?
The P4KE13HE3/73 has a guaranteed breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current (IT). This tight VBR window ensures consistent clamping behavior across production lots and supports precise overvoltage margining in 12 V automotive systems. The value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 16-Sep-2021.
Is P4KE13HE3/73 suitable for automotive applications?
Yes, P4KE13HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, glass-passivated junction, and compliance with ISO 7637-2 transient immunity standards make it appropriate for body control modules, camera power supplies, and sensor interface protection in vehicles. The HE3 suffix confirms automotive qualification.
What is the clamping voltage of P4KE13HE3/73 at rated surge current?
The P4KE13HE3/73 clamps to a maximum of 18.2 V at its rated peak pulse current of 22.0 A (10/1000 μs waveform). This VC value is measured under standardized conditions and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring safe operation of 12 V-rated ICs and MOSFETs downstream of the P4KE13HE3/73.
Does P4KE13HE3/73 have polarity markings?
Yes, P4KE13HE3/73 is a unidirectional TVS diode with a visible cathode band on the DO-41 package body. The banded end corresponds to the cathode terminal and must be connected toward the protected line (e.g., 12 V rail), while the anode connects to ground. Bidirectional variants use "CA" suffixes and lack polarity markings - P4KE13HE3/73 is not bidirectional.
What packaging and compliance does the "HE3/73" suffix indicate?
The "HE3/73" suffix denotes RoHS-compliant construction, AEC-Q101 qualification, and JESD 201 Class 2 whisker resistance - verified for automotive-grade reliability. The "/73" indicates packaging in 73" diameter tape-and-reel format (5500 pcs/reel), while "HE3" distinguishes it from commercial-grade "E3" variants. All P4KE13HE3/73 units meet UL 94 V-0 flammability and J-STD-002 solderability requirements.
