Product details
Overview
P4KE75CHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 71.3 V minimum breakdown voltage (VBR), 64.1 V maximum standoff voltage (VWM), 103 V clamping voltage (VC) at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE75CHE3/54 datasheet, P4KE75CHE3/54 pinout, P4KE75CHE3/54 application, or P4KE75CHE3/54 equivalent, this device is selected for robust ESD and surge protection in automotive power supplies, industrial sensor interfaces, and telecom line cards where AEC-Q101 qualification, low clamping ratio, and glass-passivated junction reliability are critical.
Technical Context
The P4KE75CHE3/54 operates as a unidirectional avalanche diode with a precisely controlled reverse breakdown threshold. Its 64.1 V standoff voltage ensures stable blocking under normal operation, while its 103 V clamping voltage limits transients to safe levels during 400 W, 10/1000 μs surges - delivering a clamping ratio of 1.61 (VC/VWM).
It exhibits 1.0 μA maximum reverse leakage at VWM, a 0.105 %/°C temperature coefficient of VBR, and is rated for -55 °C to +175 °C junction temperature. The device is AEC-Q101 qualified and uses a glass-passivated chip junction in a molded DO-41 epoxy package with matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Max Standoff) | 64.1 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below breakdown |
| VBR (Min Breakdown) | 71.3 V at 1.0 mA - Guaranteed avalanche initiation threshold; ensures predictable turn-on during transients |
| VC (Clamping @ IPPM) | 103 V at 3.9 A - Peak voltage seen by protected circuit during 400 W surge; determines downstream component stress |
| PPPM | 400 W - Peak pulse power handling with 10/1000 μs waveform; defines single-event surge immunity level |
| IPPM | 3.9 A - Corresponding peak pulse current at VC; used for PCB trace sizing and fuse coordination |
| TJ max | +175 °C - Maximum junction temperature; enables high-temperature automotive and industrial deployment |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |

| 175 °C max junction temperature | Supports operation in under-hood environments and high-power industrial enclosures without derating |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp positive-going surges above 64.1 V. Use Value: Withstands 400 W pulses and maintains <1.0 μA leakage at 64.1 V, preserving low-quiescent-current design integrity. |
Use Scenario: Shielding analog input pins of PLC analog I/O modules from field-wiring induced surges. IC Role / Device Role / Timing Role: Primary front-end clamp on 4–20 mA or 0–10 V sensor lines, upstream of precision op-amps and ADCs. Use Value: 103 V clamping voltage prevents damage to 12-bit+ ADCs and ensures signal integrity during 1 kV/500 A surge events. |
| Telecom Line Card Surge Suppression | Consumer Power Adapter Input Protection |
Use Scenario: Secondary protection on AC/DC converter inputs in DSLAM and ONU line cards exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Fast-response unidirectional clamp after MOV-based primary protection, absorbing residual energy. Use Value: Sub-1 ns response time and 0.105 %/°C VBR tempco ensure consistent clamping across operating temperature range. |
Use Scenario: Overvoltage safeguard on secondary-side DC outputs of wall adapters powering USB-C PD devices. IC Role / Device Role / Timing Role: Low-leakage (≤1 μA) standoff device preventing false triggering while clamping output overvoltage faults. Use Value: 64.1 V VWM aligns with 5 V–20 V adapter output ranges; DO-41 package supports automated through-hole assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Surface-mount SMB package; 75 V VBR min; 400 W rating; same 10/1000 μs waveform | Requires PCB redesign for SMT placement; better thermal performance in high-density layouts | Select when board space is constrained and reflow assembly is preferred over through-hole |
| 1.5KE75A | Higher 1500 W peak pulse power; same DO-41 package; 71.3–78.8 V VBR range; higher VC (121 V) | Used where higher surge immunity (e.g., IEC 61000-4-5 Level 5) is required, accepting larger clamping voltage | Select when system-level surge test requirements exceed 400 W but DO-41 mechanical compatibility must be retained |
Compared with SMBJ75A, P4KE75CHE3/54 offers through-hole mechanical robustness and AEC-Q101 qualification; compared with 1.5KE75A, it trades peak power for tighter clamping and lower thermal mass - making it optimal for cost-sensitive, thermally moderate automotive and industrial applications.

FAQ
What is the polarity configuration of the P4KE75CHE3/54?
The P4KE75CHE3/54 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a color band on the DO-41 package body, and it conducts only in reverse bias during overvoltage events. This configuration makes it suitable for DC rail protection where polarity is fixed, unlike bidirectional variants that suppress both positive and negative transients.
Does the P4KE75CHE3/54 meet automotive qualification standards?
Yes, the P4KE75CHE3/54 is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88365, Revision 16-Sep-2021). The HE3 suffix denotes AEC-Q101 qualification, covering stress tests including high-temperature reverse bias, temperature cycling, and ESD - validating its use in automotive power distribution and control modules.
What is the clamping voltage of the P4KE75CHE3/54 under surge conditions?
The P4KE75CHE3/54 has a maximum clamping voltage (VC) of 103 V at 3.9 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuits during transient events, directly influencing downstream component voltage ratings.
How does the P4KE75CHE3/54 differ from the P4KE75A variant?
The P4KE75CHE3/54 differs from the base P4KE75A by its HE3 suffix: it is RoHS-compliant and AEC-Q101 qualified, whereas P4KE75A-E3 is commercial grade only. Both share identical electrical specs (VBR, VC, PPPM), but P4KE75CHE3/54 undergoes additional automotive reliability testing and meets JESD201 Class 2 whisker resistance requirements.
Can the P4KE75CHE3/54 be used in bidirectional surge protection applications?
No, the P4KE75CHE3/54 is strictly unidirectional and not suitable for bidirectional protection. For symmetrical transient suppression (e.g., AC lines or data buses), Vishay specifies CA-suffix parts like P4KE75CA. Using P4KE75CHE3/54 in bidirectional configurations risks forward conduction during negative transients and inadequate protection.
