Product details
Overview
P4KE7.5CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 7.13 V minimum and 7.88 V maximum breakdown voltage at 10 mA test current, 6.40 V standoff voltage, 11.3 V maximum clamping voltage at 35.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE7.5CAHE3/54 datasheet, P4KE7.5CAHE3/54 pinout, P4KE7.5CAHE3/54 application, or P4KE7.5CAHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, bidirectional clamping behavior, and real-world use cases in automotive and industrial transient protection circuits.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse (or either polarity for bidirectional types) voltage exceeds VBR, it avalanches to limit transient energy. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 0.01% duty cycle pulses.
Designed for unclamped inductive switching events and lightning-induced surges, it sustains 400 W peak pulse power per 10/1000 μs waveform and maintains clamping performance across -55 °C to +175 °C junction temperature range. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min / max | 7.13 V / 7.88 V at 10 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 6.40 V - maximum continuous working voltage before leakage exceeds 500 μA; sets safe operating margin below VBR |
| VC @ IPPM | 11.3 V at 35.4 A - clamping voltage during 400 W transient; determines protected circuit's maximum stress level |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform; defines single-event surge robustness |
| IPPM | 35.4 A - peak pulse current corresponding to VC; used to size series impedance and verify PCB trace survival |
| TJ max | +175 °C - maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional configuration; body diameter 2.0–2.7 mm, lead diameter 0.71–0.86 mm, overall length ≥25.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No cathode band; identical clamping behavior in both directions - simplifies PCB layout for AC or floating signal lines |
| Lead 1 / Lead 2 | Current path terminals | Leads serve as thermal and electrical interfaces; RθJL = 66 °C/W enables direct soldering to copper pour for thermal relief |
Key Features
| Feature | Design Value |

| AEC-Q101 qualified (HE3 suffix) | Validated for automotive under-hood applications including temperature cycling, humidity bias, and mechanical shock tests |
| UL 94 V-0 compliant molding compound | Prevents flame propagation in enclosed enclosures - required for industrial control cabinet and EV charging station designs |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients - improves margin for 3.3 V or 5 V logic-level ICs downstream |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching noise in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed across differential or single-ended signal lines upstream of interface ICs. Use Value: Clamps transients to ≤11.3 V while maintaining <500 μA leakage at 6.4 V - preserves signal integrity and prevents latch-up in 5 V tolerant receivers. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against field-wiring surges and relay contact bounce. IC Role / Device Role / Timing Role: Primary overvoltage clamp on terminal block side of optocoupler input stage. Use Value: Absorbs 400 W surges without failure, enabling compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity requirements. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding RS-485 transceivers and Ethernet PHY magnetics from induced lightning surges in outdoor telecom cabinets. IC Role / Device Role / Timing Role: First-stage transient suppressor on twisted-pair line side, before common-mode chokes and TVS arrays. Use Value: Symmetrical clamping ensures equal protection for both conductors; DO-41 footprint allows manual rework and automated placement in space-constrained modules. |
Use Scenario: Suppressing back-EMF spikes from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Across-motor terminals or across relay coil to divert inductive kickback energy. Use Value: Withstands 40 A non-repetitive forward surge (IFSM) and 175 °C junction temperature - survives repeated motor startups in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | DO-214AA package; 7.0 V nominal VBR; 600 W PPPM; lower clamping voltage (11.2 V) | Higher power density; surface-mount only; requires reflow-compatible layout | Select for space-constrained SMT designs needing higher surge rating and tighter VC tolerance |
| 1.5KE7.5CA | DO-201AD package; same VBR/VC specs; 1500 W PPPM; larger body and higher IPPM (123 A) | Higher energy absorption; through-hole compatible but larger footprint than DO-41 | Select when legacy through-hole assembly is required and surge threat level exceeds 400 W |
Compared with SMBJ7.0CA and 1.5KE7.5CA, P4KE7.5CAHE3/54 offers AEC-Q101 qualification and DO-41 compatibility in cost-sensitive automotive and industrial through-hole assemblies - balancing reliability, legacy manufacturability, and standardized surge ratings.

FAQ
What is the breakdown voltage range of the P4KE7.5CAHE3/54?
The P4KE7.5CAHE3/54 has a guaranteed breakdown voltage range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight VBR window ensures consistent clamping onset across production lots and supports precise overvoltage margining in 5 V and 6 V systems where the P4KE7.5CAHE3/54 is commonly deployed.
Is the P4KE7.5CAHE3/54 suitable for automotive applications?
Yes, the P4KE7.5CAHE3/54 carries the HE3 suffix, confirming full AEC-Q101 qualification - including temperature cycling, high-temperature reverse bias, and mechanical shock testing. Its -55 °C to +175 °C operating range and DO-41 package with matte tin leads make it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal stress is mandatory.
How does the bidirectional configuration of P4KE7.5CAHE3/54 affect its usage?
The P4KE7.5CAHE3/54 is inherently bidirectional - meaning it clamps symmetrically for both positive and negative transients without polarity marking. This eliminates orientation errors during assembly and simplifies protection of AC-coupled lines, differential buses (e.g., RS-485), or floating sensor outputs where voltage polarity reversal is possible, unlike unidirectional variants such as P4KE7.5A.
What is the maximum clamping voltage of P4KE7.5CAHE3/54 under surge conditions?
The P4KE7.5CAHE3/54 clamps to a maximum of 11.3 V at its rated peak pulse current of 35.4 A (10/1000 μs waveform). This value is measured under standardized test conditions and defines the highest voltage seen by downstream circuitry during a worst-case transient - critical for ensuring compatibility with 5 V logic families and analog front-end components.
Does P4KE7.5CAHE3/54 require heatsinking in typical applications?
No external heatsink is required for P4KE7.5CAHE3/54 in single-event transient suppression due to its short pulse duration (≤1000 μs) and low average power. However, its thermal resistance junction-to-lead is 66 °C/W, so mounting directly to ≥1 cm² copper pour improves reliability during repetitive surges. Continuous power dissipation is limited to 1.5 W at 75 °C lead temperature (PD rating).
