Product details
Overview
P6KE43AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of sensitive electronics. It features a 40.9 V minimum breakdown voltage (VBR), 36.8 V maximum standoff voltage (VWM), 59.3 V clamping voltage at 10.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and signal lines in automotive ECUs and industrial motor drives.
For engineers reviewing the P6KE43AHE3/54 datasheet, P6KE43AHE3/54 pinout, P6KE43AHE3/54 application, or P6KE43AHE3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, DO-15 mechanical compatibility, and clamping performance under repetitive 0.01% duty cycle surges.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 36.8 V, it avalanches to limit transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, critical for consistent clamping across repeated transients.
Designed for bidirectional-capable systems requiring unidirectional suppression, it delivers 10.1 A peak pulse current (IPPM) at 59.3 V clamping voltage while maintaining <1.0 μA reverse leakage at VWM, enabling reliable operation in 12 V and 24 V automotive supply domains without standby power penalty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36.8 V maximum - defines highest continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 40.9 V / 45.2 V at 1.0 mA - specifies avalanche onset range for design margining and tolerance stack-up |
| VC @ IPPM | 59.3 V at 10.1 A - maximum clamped voltage seen by protected circuit during 10/1000 μs surge |
| PPPM | 600 W - peak transient power dissipation capability with 0.01% duty cycle, defining surge survivability |
| TJ max | +175 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures |
| RθJL | 20 °C/W - thermal resistance from junction to lead, supporting PCB copper pour design for sustained surge handling |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules per stress test requirements |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage stress on downstream MOSFETs and ICs during fast transients |
| Matte tin-plated leads | Enables robust solder joint formation and compliance with JESD 22-B102 wetting balance testing |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A | Same VWM (36.8 V), lower PPPM (400 W), SMA package (surface-mount) | Requires PCB rework for SMT layout; unsuitable for through-hole legacy designs | Select when board space is constrained and automated assembly is prioritized over axial lead serviceability. |
| 1.5KE43A | Same VWM/VBR specs, identical DO-15 package, but commercial-grade (not AEC-Q101 qualified) | Lacks automotive qualification; limited to industrial/commercial environments with lower reliability demands | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated. |
Compared with SMAJ43A and 1.5KE43A, P6KE43AHE3/54 uniquely combines AEC-Q101 qualification, 600 W surge rating, and DO-15 through-hole compatibility - making it the only option qualified for automotive under-hood deployment without layout change or derating.

FAQ
What is the maximum clamping voltage of P6KE43AHE3/54 under standard surge conditions?
The P6KE43AHE3/54 exhibits a maximum clamping voltage (VC) of 59.3 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 10.1 A. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6KE43AHE3/54 suitable for automotive applications?
Yes, P6KE43AHE3/54 is AEC-Q101 qualified, confirming its reliability for automotive use including engine control units, body electronics, and infotainment power supplies. The HE3 suffix explicitly denotes AEC-Q101 qualification, high-temperature operation up to +175 °C, and compliance with whisker testing per JESD 201 Class 2 - distinguishing it from commercial-grade variants.
How does the DO-15 package of P6KE43AHE3/54 affect thermal performance?
The DO-15 (DO-204AC) package of P6KE43AHE3/54 provides a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling effective heat transfer to PCB copper pours or chassis mounts. Its axial-leaded construction supports manual rework and high-current lead soldering, while the molded epoxy meets UL 94 V-0 flammability - essential for enclosed automotive and industrial assemblies.
What is the reverse leakage current specification for P6KE43AHE3/54 at its standoff voltage?
At its maximum standoff voltage (VWM = 36.8 V) and ambient temperature (TA = 25 °C), the P6KE43AHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage ensures minimal power loss in always-on systems and avoids interference with precision analog sensing or battery-backed circuits.
Does P6KE43AHE3/54 have bidirectional capability?
No, P6KE43AHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants in the same family use the "CA" suffix (e.g., P6KE43CA). Using P6KE43AHE3/54 in AC-coupled or bipolar signal paths would result in forward conduction during negative half-cycles - requiring careful circuit topology verification.
