Product details
Overview
P6KE13HE3/73 from Vishay General Semiconductor is a uni-directional 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 (10/1000 μs), 13.7 V maximum breakdown voltage at 1 mA, 11.1 V stand-off voltage, 18.2 V maximum clamping voltage at 33.0 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE13HE3/73 datasheet, P6KE13HE3/73 pinout, P6KE13HE3/73 application, or P6KE13HE3/73 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, surge current handling for ISO 7637-2 pulse 1/2b/5a compliance, thermal resistance (RθJL = 20 °C/W), and RoHS-compliant, whisker-tested (JESD 201 Class 2) matte tin leads.
Technical Context
The P6KE13HE3/73 operates as a silicon avalanche diode with glass-passivated junction, delivering bi-polar clamping behavior only in reverse-biased mode (uni-directional polarity). Its 10/1000 μs waveform response enables suppression of fast transients from inductive switching and ESD events while maintaining low dynamic impedance during conduction.
It exhibits a +0.081 %/°C temperature coefficient of breakdown voltage and 3.5 V maximum forward voltage at 50 A - critical for fault-current path analysis in fuse-coordinated protection schemes. The device is rated for -55 °C to +175 °C operating junction temperature and derates linearly above 25 °C ambient per Fig. 2.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump transients up to 40 V and inductive kickback from solenoids. IC Role / Device Role / Timing Role: Primary clamping device placed at board entry point to limit voltage seen by LDOs, MCUs, and CAN transceivers. Use Value: Clamps 33 A surge to ≤18.2 V within nanoseconds, preventing latch-up or gate oxide rupture in downstream ICs. |
Use Scenario: 4–20 mA current loop sensors in factory automation subject to cable ESD and nearby motor switching noise. IC Role / Device Role / Timing Role: Line-side TVS on analog input conditioning stage upstream of op-amps and ADCs. Use Value: Limits transient-induced offset errors and prevents saturation recovery delay by clamping <100 ns after event onset. |
| Consumer Power Adapter Input | Telecom Line Card Surge Protection |
Use Scenario: AC/DC adapter secondary-side output filtering where cost-sensitive overvoltage protection is required. IC Role / Device Role / Timing Role: Secondary-side TVS across regulated 5 V or 3.3 V rail to absorb capacitor discharge surges and rectifier reverse recovery spikes. Use Value: Withstands 600 W pulses without degradation, enabling single-device protection instead of multi-stage RC+TVS solutions. |
Use Scenario: DSL or Ethernet line cards interfacing with unshielded outdoor cabling susceptible to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage coarse protection ahead of gas discharge tube (GDT) and polymer PPTC in hybrid protection architecture. Use Value: Fast response (<1 ns) initiates clamping before GDT fires, reducing let-through energy to <10 mJ for downstream components. |
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 | Lower peak pulse power (400 W), SMA package (surface-mount), 13.3–14.7 V VBR range | Preferred for space-constrained PCBs; less suitable for high-energy automotive load dump | Select SMAJ13A when board area is limited and surge energy does not exceed 400 W capability |
| 1.5KE13A | Same DO-15 package but higher 1500 W rating, 12.4–13.7 V VBR, no AEC-Q101 or HE3 whisker certification | Used in industrial mains-powered equipment where automotive qualification is unnecessary | Choose 1.5KE13A for higher surge margin in non-automotive applications where qualification is not mandated |
Compared with P6KE13HE3/73, SMAJ13A trades off surge capacity for SMT footprint, while 1.5KE13A offers greater energy handling but lacks automotive reliability validation - making P6KE13HE3/73 optimal for cost-sensitive, AEC-Q101–required 12 V systems.

FAQ
What is the clamping voltage of P6KE13HE3/73 and why does it matter?
The P6KE13HE3/73 has a maximum clamping voltage (VC) of 18.2 V at 33.0 A peak pulse current (10/1000 μs). This value defines the highest voltage that will appear across the protected circuit during a surge event. It matters because it must remain safely below the absolute maximum voltage rating of downstream ICs - for example, ensuring a 20 V-rated MCU survives without damage. The 18.2 V clamping is achieved via controlled avalanche breakdown and is validated per JEDEC standards.
Is P6KE13HE3/73 suitable for automotive applications?
Yes, P6KE13HE3/73 is AEC-Q101 qualified and carries the HE3 suffix indicating JESD 201 Class 2 whisker resistance - both mandatory for automotive under-hood and cabin electronics. Its -55 °C to +175 °C junction temperature range, 600 W surge rating, and DO-15 mechanical robustness make it appropriate for engine control modules, body controllers, and ADAS power supplies where transient immunity is critical.
How does the HE3 suffix differ from E3 in P6KE13HE3/73?
The HE3 suffix in P6KE13HE3/73 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker testing, whereas E3 indicates RoHS compliance and JESD 201 Class 1A whisker resistance only. HE3 devices undergo additional stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - confirming suitability for automotive safety-critical functions where field reliability is non-negotiable.
What is the thermal resistance of P6KE13HE3/73 and how is it used in design?
P6KE13HE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W. Designers use this value to estimate junction temperature rise above lead temperature: TJ = TL + (PD × RθJL). For example, at 5.0 W steady-state dissipation and 75 °C lead temperature (per Fig. 5), TJ ≈ 175 °C - matching its absolute maximum rating. This informs heatsinking requirements and safe operating area boundaries during repetitive surge events.
Can P6KE13HE3/73 be used in bi-directional protection circuits?
No, P6KE13HE3/73 is a uni-directional TVS diode - its cathode band marks the avalanche terminal, and it conducts only when reverse-biased beyond VBR. For bi-directional protection (e.g., AC lines or differential data buses), a CA-suffixed variant like P6KE13CA must be used. Using P6KE13HE3/73 in bi-directional configurations risks forward conduction during positive half-cycles, leading to excessive power dissipation and potential failure.
