Product details
Overview
P4KE160CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR at 1 mA), 219 V clamping voltage at 1.8 A peak pulse current (IPPM), and 400 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 P4KE160CHE3/54 datasheet, P4KE160CHE3/54 pinout, P4KE160CHE3/54 application, or P4KE160CHE3/54 equivalent, key selection criteria include verified AEC-Q101 qualification, DO-41 mechanical compatibility, bidirectional-capable variant availability (P4KE160C), and thermal resistance (RθJL = 66 °C/W) for lead-mounted transient energy dissipation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (152–168 V), it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM).
Rated for 400 W peak pulse power (10/1000 μs), it sustains repetitive transients at 0.01 % duty cycle and handles up to 40 A non-repetitive forward surge (8.3 ms half-sine). Junction temperature range spans −55 °C to +175 °C, supporting under-hood automotive deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - precise avalanche initiation threshold for reliable overvoltage detection |
| VC (Clamping Voltage) | 219 V at IPPM = 1.8 A - limits voltage seen by protected ICs during ESD or load dump events |
| PPPM (Peak Pulse Power) | 400 W - energy-handling capacity for 10/1000 μs transients per JEDEC standards |
| RθJL (Junction-to-Lead Thermal Resistance) | 66 °C/W - enables effective heat transfer to PCB copper or heatsinked leads |
| TJ max. | +175 °C - supports operation in high-temperature environments including engine compartments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress test requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | DO-214AA package, 1.5× smaller footprint, 600 W PPPM rating, higher IPPM (3.2 A) | Better suited for space-constrained PCBs; requires revised layout due to SMD mounting | Select SMBJ160A when board area is limited and higher surge margin is needed |
| P4KE160A-E3/54 | Same DO-41 package and electrical specs, but commercial-grade (non-AEC-Q101 qualified) | Limited to non-automotive applications where extended temperature validation is not required | Choose P4KE160A-E3/54 for cost-sensitive industrial controls without automotive qualification mandates |
Compared with SMBJ160A and P4KE160A-E3/54, the P4KE160CHE3/54 uniquely combines AEC-Q101 qualification, axial DO-41 through-hole compatibility, and proven thermal performance (RθJL = 66 °C/W) for high-reliability automotive harness connections.

FAQ
What is the clamping voltage of the P4KE160CHE3/54 at its rated peak pulse current?
The P4KE160CHE3/54 has a maximum clamping voltage (VC) of 219 V at 1.8 A peak pulse current (IPPM), measured using the standard 10/1000 μs waveform. This value ensures protected circuitry remains within safe voltage limits during surge events. The P4KE160CHE3/54 maintains this clamping performance across its full operating temperature range of −55 °C to +175 °C.
Is the P4KE160CHE3/54 suitable for automotive applications?
Yes, the P4KE160CHE3/54 is AEC-Q101 qualified and rated for junction temperatures up to +175 °C, making it suitable for under-hood automotive applications such as engine control units and body electronics. Its glass-passivated junction and DO-41 mechanical robustness meet automotive reliability requirements. The P4KE160CHE3/54 is explicitly listed in Vishay's AEC-Q101 qualified product table.
How does the HE3 suffix affect the P4KE160CHE3/54 specification?
HE3 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike the E3 suffix (Class 1A), HE3 ensures enhanced reliability for automotive and high-reliability industrial use. The P4KE160CHE3/54 retains identical electrical parameters as its E3 counterpart but adds validated stress-test compliance for mission-critical deployments.
What is the standoff voltage (VWM) of the P4KE160CHE3/54, and why does it matter?
The P4KE160CHE3/54 has a standoff voltage (VWM) of 136 V, meaning it remains non-conductive below this reverse voltage level. This parameter prevents false triggering during normal operation while allowing rapid avalanche response above VWM. For 12 V automotive systems with load dump protection, VWM must exceed nominal rail voltage plus tolerance - the P4KE160CHE3/54 satisfies this for 24 V and higher architectures.
Can the P4KE160CHE3/54 be used in bidirectional configurations?
No - the P4KE160CHE3/54 is unidirectional only, indicated by the "A" suffix and cathode band marking. For bidirectional protection, the P4KE160CA variant must be used. The P4KE160CHE3/54 conducts only in reverse bias during clamping and blocks forward current beyond VF ≈ 5.0 V; using it in AC-coupled or symmetrical surge scenarios would require external circuitry or part substitution.
