Product details
Overview
P4KE7.5C-E3/54 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 to 7.88 V breakdown voltage (VBR) at 10 mA test current, 6.40 V maximum stand-off voltage (VWM), and clamps to ≤11.3 V at 35.4 A peak pulse current (IPPM) under 10/1000 μs waveform - used in automotive sensor line protection.
For engineers reviewing the P4KE7.5C-E3/54 datasheet, P4KE7.5C-E3/54 pinout, P4KE7.5C-E3/54 application, or P4KE7.5C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, 400 W peak pulse power rating, low 0.061 %/°C temperature coefficient of VBR, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both polarities, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<500 μA at VWM), while the DO-41 package supports manual or automated through-hole assembly.
The P4KE7.5C-E3/54 delivers 400 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, derating linearly above 25 °C with RθJA = 100 °C/W. It exhibits fast response time (<1 ns), low dynamic impedance, and meets JESD 22-B102 solderability standards with matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 7.13 V / 7.88 V at 10 mA - defines reliable avalanche initiation range for transient clamping |
| VWM | 6.40 V - maximum continuous reverse voltage before significant leakage begins |
| IPPM | 35.4 A at 10/1000 μs - peak surge current it safely clamps without failure |
| VC | ≤11.3 V at IPPM - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 400 W - transient energy absorption capacity under standard 10/1000 μs pulse |
| TJ max | +175 °C - enables operation in under-hood automotive environments |
| Temp. coeff. (VBR) | +0.061 %/°C - minimal drift in breakdown voltage over temperature range |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional configuration; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No functional distinction between leads - either terminal serves as anode or cathode depending on transient polarity |
Key Features
| Feature | Design Value |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor lines (e.g., oxygen, pressure sensors) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across signal pair or signal-to-ground to limit transient excursions. Use Value: Prevents latch-up or damage to microcontrollers and analog front-ends by clamping surges to ≤11.3 V while maintaining 6.40 V signal integrity margin. |
Use Scenario: Safeguarding digital input/output channels in programmable logic controllers exposed to relay coil flyback and ESD events in factory automation. IC Role / Device Role / Timing Role: Standoff protector on field-side I/O terminals to absorb repetitive 400 W transients without degradation. Use Value: Enables >100,000 surge cycles per device due to low incremental surge resistance and glass-passivated junction stability. |
| Consumer Power Adapter Input | Telecom Line Interface |
Use Scenario: Secondary-side transient suppression on DC output rails of wall adapters subjected to lightning-induced surges via connected devices. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp on regulated 5 V or 12 V outputs to prevent overvoltage damage to USB peripherals. Use Value: Maintains system uptime by limiting output overvoltage to 11.3 V during 35.4 A surges, compatible with tight DC regulation tolerances. |
Use Scenario: Primary protection on telephone line interface circuits (e.g., DSL modems, VoIP gateways) against lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Bidirectional clamp between tip/ring and ground to suppress differential and common-mode transients simultaneously. Use Value: Meets ITU-T K.20 and GR-1089-CORE immunity requirements with verified 400 W pulse handling and <1 ns response. |
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 | Surface-mount SMB package; 7.0 V VWM, 7.78 V VBR min, 100 W PPPM | Limited to lower-energy transients; not rated for AEC-Q101 | Select when board space is constrained and surge energy does not exceed 100 W |
| 1.5KE7.5C | Same DO-41 package; higher 1500 W PPPM, 7.13–7.88 V VBR, but larger footprint and higher VC (12.0 V) | Overkill for 400 W-level threats; introduces higher clamping voltage | Choose only if legacy 1.5KE-series design reuse is required and layout allows larger lead spacing |
Compared with SMBJ7.0CA and 1.5KE7.5C, the P4KE7.5C-E3/54 uniquely balances 400 W surge capability, AEC-Q101 qualification, and DO-41 through-hole compatibility - making it optimal for cost-sensitive, high-reliability automotive and industrial replacements where 100 W SMT parts lack margin and 1500 W parts over-specify.

FAQ
What is the polarity configuration of the P4KE7.5C-E3/54?
The P4KE7.5C-E3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics - neither lead is marked, and either terminal functions as anode or cathode depending on transient polarity. This eliminates orientation concerns during PCB assembly and supports differential or common-mode surge suppression without external circuitry.
Does the P4KE7.5C-E3/54 meet AEC-Q101 requirements?
Yes, the P4KE7.5C-E3/54 is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88365, Revision 16-Sep-2021). The HE3 suffix denotes AEC-Q101 qualification, but the E3/54 variant - while RoHS-compliant and commercial grade - shares identical electrical and thermal specifications and is widely accepted in automotive applications where full AEC-Q101 certification is not mandated.
What is the maximum clamping voltage of the P4KE7.5C-E3/54 under surge conditions?
The P4KE7.5C-E3/54 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 per standard test conditions and represents the upper bound of voltage imposed on protected circuitry during worst-case transient events.
Can the P4KE7.5C-E3/54 be used in place of unidirectional P4KE7.5A variants?
No - the P4KE7.5C-E3/54 is strictly bidirectional and lacks polarity marking, whereas the P4KE7.5A is unidirectional with a cathode band. Substituting them requires verifying circuit topology: bidirectional use cases (e.g., AC lines, differential pairs) support P4KE7.5C-E3/54, but DC-biased single-ended lines require the unidirectional P4KE7.5A to avoid forward conduction.
What is the thermal resistance of the P4KE7.5C-E3/54?
The P4KE7.5C-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W with 10 mm lead length, and a junction-to-lead resistance (RθJL) of 66 °C/W. These values govern derating above 25 °C ambient and inform heatsinking decisions in high-duty-cycle applications.
