Product details
Overview
P6KE43HE3/54 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 40.9 V minimum breakdown voltage (VBR), 36.8 V stand-off voltage (VWM), 59.3 V maximum clamping voltage (VC) at 10.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial sensor interfaces, and power supply input stages.
For engineers reviewing the P6KE43HE3/54 datasheet, P6KE43HE3/54 pinout, P6KE43HE3/54 application, or P6KE43HE3/54 equivalent, this AEC-Q101 qualified TVS offers validated surge immunity for 12 V/24 V automotive systems, precise clamping performance under repetitive transients, and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering.
Technical Context
The P6KE43HE3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering bi-directional surge suppression capability only when used in symmetrical configurations - though the device itself is uni-directional (cathode-banded). Its 20 °C/W junction-to-lead thermal resistance enables effective heat dissipation during 8.3 ms half-sine surges up to 100 A (IFSM).
Clamping behavior is defined by low incremental surge resistance and fast response time (<1 ns), with VC = 59.3 V measured at IPPM = 10.1 A (10/1000 µs). Temperature coefficient of VBR is +0.101 %/°C, confirming positive drift with junction heating - critical for thermal stability analysis in high-ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36.8 V - maximum continuous reverse working voltage before leakage exceeds 1 µA; sets safe operating margin below system nominal voltage (e.g., 36 V rail) |
| VBR (min/max) | 40.9 V / 45.2 V at 1 mA test current - defines guaranteed avalanche onset range; ensures consistent turn-on across production lots |
| VC @ IPPM | 59.3 V at 10.1 A - clamped voltage seen by protected circuit during worst-case 600 W transient; determines downstream component stress |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform; validates robustness against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges |
| TJ max. | +175 °C - maximum junction temperature; supports operation in under-hood automotive locations and sealed industrial enclosures |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per AEC specification |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; cathode indicated by color band on one end; compliant with UL 94 V-0 flammability rating.

| Matte tin plating (J-STD-002 compliant) | Ensures reliable solder wetting and intermetallic formation during reflow or wave soldering processes |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream MOSFETs, regulators, and microcontrollers during surge events |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ43A | DO-214AA package; 43 V VBR min = 45.6 V; VC = 69.4 V @ 8.6 A; 600 W rating | Higher clamping voltage (+10.1 V) and lower IPPM; surface-mount footprint replaces through-hole DO-15 | Select SMBJ43A for space-constrained PCBs where reflow assembly is preferred and higher clamping is acceptable. |
| 1.5KE43A | DO-201AD package; same VBR/VC specs; 1500 W peak power; larger thermal mass | Higher surge capacity but longer lead length increases inductance; less suitable for high-frequency transients | Choose 1.5KE43A when protecting against multi-pulse load dumps or extended surge durations exceeding single-event limits. |
Compared with P6KE43HE3/54, SMBJ43A trades lower mounting inductance and smaller footprint for higher clamping voltage, while 1.5KE43A provides greater energy absorption at the cost of board area and layout sensitivity to parasitic inductance.

FAQ
What is the polarity configuration of P6KE43HE3/54?
P6KE43HE3/54 is a uni-directional Transient Voltage Suppressor, with the cathode identified by a color band on the DO-204AC package. It conducts in reverse bias during overvoltage events and blocks forward current up to 3.5 V at 50 A, as specified in the Vishay datasheet revision 18-Sep-12. This polarity is essential for correct placement in DC power rail protection circuits.
Is P6KE43HE3/54 qualified for automotive use?
Yes, P6KE43HE3/54 carries the HE3 suffix, which denotes AEC-Q101 qualification per Vishay's ordering nomenclature. It has passed stress tests including high-temperature operating life, temperature cycling, unbiased highly accelerated stress testing, and ESD per JESD22-A114 - making it suitable for under-hood and chassis-mounted automotive applications.
What is the maximum clamping voltage of P6KE43HE3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE43HE3/54 is 59.3 V, measured at a peak pulse current (IPPM) of 10.1 A using the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events.
How does the HE3 suffix differ from E3 in P6KE43HE3/54?
The HE3 suffix in P6KE43HE3/54 indicates AEC-Q101 qualification and JESD201 Class 2 whisker resistance, whereas E3 denotes commercial-grade RoHS compliance only (JESD201 Class 1A). Both share identical electrical specifications and DO-204AC packaging, but HE3 is required for automotive and mission-critical industrial deployments.
What is the thermal resistance specification for P6KE43HE3/54?
P6KE43HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer from the silicon die to PCB copper or heatsink via its leads. This value supports sustained power dissipation up to 5.0 W at TL = 75 °C and informs thermal design for high-duty-cycle surge environments.
