Product details
Overview
P6KE30HE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 30 V breakdown voltage (VBR min/max = 28.5–31.5 V), 41.4 V maximum clamping voltage at 14.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive ECUs, industrial PLC I/O modules, and telecom power supplies.
For engineers reviewing the P6KE30HE3/73 datasheet, P6KE30HE3/73 pinout, P6KE30HE3/73 application, or P6KE30HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, 1.0 mA test current specification, 25.6 V stand-off voltage, and 1.0 μA reverse leakage at VWM, critical for low-power sensor interface protection and automotive-grade reliability validation.
Technical Context
This device operates as a voltage-clamping surge protector using an avalanche breakdown mechanism. Its glass-passivated junction ensures stable VBR tolerance (±5 %), low incremental surge resistance, and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced transients, and inductive switching spikes.
The P6KE30HE3/73 is rated for 175 °C maximum junction temperature and exhibits a +0.097 %/°C temperature coefficient of VBR. Its thermal resistance is 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), supporting reliable operation under repetitive surge conditions when mounted on PCB copper areas per JEDEC standards.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12 V/24 V battery-supplied ECUs exposed to load dump and alternator transients. IC Role / Device Role / Timing Role: Primary clamping element placed between power rail and ground, responding within <1 ns to suppress >100 V spikes. Use Value: Limits rail voltage to ≤41.4 V during 14.5 A surges, preventing damage to 3.3 V/5 V logic and CAN transceivers. |
Use Scenario: 4–20 mA current loop sensors in factory automation subject to ESD and cable discharge events. IC Role / Device Role / Timing Role: Uni-directional TVS shunting transients from signal line to local ground, preserving analog accuracy. Use Value: Maintains ≤1.0 μA leakage at 25.6 V, avoiding offset errors in precision current measurement circuits. |

IC Role / Device Role / Timing Role: Suppresses inductive kickback from motor coil commutation across power FETs. Use Value: Withstands 100 A non-repetitive forward surge (IFSM), protecting gate drivers during stall conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | DO-214AA package, 33.3 V VBR min, 48.4 V VC @ 12.3 A, same 600 W rating | Surface-mount footprint; higher VC increases downstream voltage stress | Select when board space constraints require SMD layout and thermal coupling to copper is optimized |
| 1.5KE30A | Same DO-204AC package, 28.5–31.5 V VBR, but 44.0 V VC @ 13.6 A and no AEC-Q101 qualification | Lacks automotive qualification; higher clamping voltage reduces protection margin | Acceptable for commercial-grade industrial controls where AEC-Q101 is not mandated |
Compared with SMBJ30A and 1.5KE30A, the P6KE30HE3/73 delivers tighter clamping (41.4 V vs. ≥44.0 V), AEC-Q101 certification for automotive deployment, and axial-leaded through-hole mounting ideal for high-surge reliability in ruggedized power modules.

FAQ
What is the clamping voltage of the P6KE30HE3/73 under maximum surge conditions?
The P6KE30HE3/73 has a maximum clamping voltage (VC) of 41.4 V at 14.5 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number 88369) and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The P6KE30HE3/73 maintains this clamping performance across its specified operating temperature range.
Is the P6KE30HE3/73 suitable for automotive applications?
Yes, the P6KE30HE3/73 is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including engine control units, body control modules, and ADAS sensor interfaces. Its 175 °C maximum junction temperature, robust surge rating, and RoHS-compliant HE3 suffix (JESD 201 Class 2 whisker resistance) meet stringent automotive reliability requirements. The P6KE30HE3/73 is explicitly listed in Vishay's AEC-Q101 qualified product documentation.
What does the 'HE3' suffix indicate in P6KE30HE3/73?
The 'HE3' suffix in P6KE30HE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes the part from commercial-grade 'E3' variants and confirms compliance with automotive reliability standards. The P6KE30HE3/73 uses matte tin-plated leads and meets UL 94 V-0 flammability requirements - all verified in Vishay's official ordering information and mechanical data.
How does the P6KE30HE3/73 compare to bi-directional TVS diodes?
The P6KE30HE3/73 is a uni-directional TVS diode, meaning it protects only against reverse-polarity transients on DC lines - unlike bi-directional types (e.g., P6KE30CA) that clamp both polarities. Its cathode band must be oriented toward the protected line. For AC-coupled or floating signal lines, a bi-directional variant would be required; the P6KE30HE3/73 is optimized for grounded DC rails where polarity is fixed and forward conduction is not expected during normal operation.
What is the thermal resistance of the P6KE30HE3/73, and how does it affect layout?
The P6KE30HE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. These values require adequate PCB copper area connected to both leads - especially the cathode - to dissipate surge energy and maintain junction temperature below 175 °C. Layout best practices include ≥10 mm² copper pour per lead and minimizing trace length, as validated in Vishay's thermal derating curves (Fig. 5).
