Product details
Overview
P6KE43CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 43 V breakdown voltage (VBR min/max = 40.9–45.2 V at 1.0 mA), 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 - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE43CAHE3/54 datasheet, P6KE43CAHE3/54 pinout, P6KE43CAHE3/54 application, or P6KE43CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, thermal resistance (RθJL = 20 °C/W), and low leakage (<1.0 μA at VWM) under standby conditions.
Technical Context
This device operates as a voltage-clamping protection element in both polarities, leveraging an avalanche breakdown mechanism to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5%), fast response time (<1.0 ns), and low incremental surge resistance - critical for suppressing ESD, inductive switching spikes, and lightning-induced surges.
Rated for -55 °C to +175 °C operating junction temperature, it supports high-reliability applications where thermal derating must be applied above 25 °C ambient. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, distinguishing it from commercial-grade E3 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 40.9 V / 45.2 V at 1.0 mA - defines precise clamping onset threshold in both directions |

FAQ
What does the 'CA' suffix indicate in P6KE43CAHE3/54?
The 'CA' suffix denotes that P6KE43CAHE3/54 is a bidirectional Transient Voltage Suppressor, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants (e.g., P6KE43A), this device has no cathode marking and functions identically regardless of terminal orientation - essential for AC-coupled or floating signal line protection where polarity is undefined.
Is P6KE43CAHE3/54 suitable for automotive applications?
Yes, P6KE43CAHE3/54 is AEC-Q101 qualified (confirmed by the 'HE3' suffix), tested for high-temperature operating life, thermal cycling, and unbiased highly accelerated stress testing. It meets automotive requirements for under-hood and cabin electronics, including body control modules and sensor interfaces where transient immunity to load dump and ESD is mandatory.
How does the clamping voltage VC of P6KE43CAHE3/54 compare to its breakdown voltage VBR?
P6KE43CAHE3/54 has a minimum VBR of 40.9 V and maximum clamping voltage VC of 59.3 V at 10.1 A - yielding a clamping ratio of approximately 1.39. This relatively low ratio ensures minimal overvoltage stress on downstream components during surge events, especially important for protecting 3.3 V or 5 V logic ICs powered from regulated rails downstream of the TVS.
What is the significance of the 'HE3' suffix in P6KE43CAHE3/54?
The 'HE3' suffix in P6KE43CAHE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade 'E3' versions and confirms suitability for automotive applications requiring extended reliability validation, including high-temperature storage and operational lifetime testing beyond standard industrial specifications.
Can P6KE43CAHE3/54 replace P6KE43A in an existing design?
No - P6KE43CAHE3/54 is bidirectional while P6KE43A is unidirectional, with different electrical behavior under forward bias. Substituting them requires verifying circuit polarity, checking for unintended conduction paths, and confirming that the protected IC tolerates symmetrical clamping. Direct replacement is not recommended without schematic and layout review, as forward voltage drop (VF) and leakage characteristics differ significantly between types.
