Product details
Overview
P4KE7.5CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on DC power rails and signal lines. It features 7.13 V to 7.88 V breakdown voltage (VBR) at 10 mA test current, 6.40 V stand-off voltage (VWM), 11.3 V maximum clamping voltage (VC) at 35.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the P4KE7.5CHE3/54 datasheet, P4KE7.5CHE3/54 pinout, P4KE7.5CHE3/54 application, or P4KE7.5CHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 0.061 %/°C VBR temperature coefficient, and compatibility with lead-free reflow and wave soldering per J-STD-002.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation (blocking up to 6.40 V), then avalanche-conducting above 7.13 V to limit transient overvoltage. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<500 μA at VWM).
Designed for 10/1000 μs surge immunity per IEC 61000-4-5, it delivers 35.4 A peak pulse current with 11.3 V clamping, enabling robust protection of downstream MOSFETs and ICs without sacrificing response time - typical turn-on within picoseconds due to junction capacitance <100 pF at zero bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - defines reliable conduction onset range under production tolerance |
| VWM | 6.40 V - maximum continuous reverse voltage before leakage exceeds 500 μA |
| VC @ IPPM | 11.3 V at 35.4 A - clamped voltage seen by protected circuit during 400 W transient |
| PPPM | 400 W - peak surge power handling with 10/1000 μs waveform, 0.01 % duty cycle |
| IFSM | 40 A - non-repetitive forward surge rating (8.3 ms half-sine), critical for inrush-limited inputs |
| TJ max | +175 °C - enables operation in under-hood automotive environments and high-power industrial enclosures |
| Temp. Coeff. | +0.061 %/°C - minimal VBR drift over temperature, ensuring consistent clamping across -55 °C to +175 °C |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; matte tin-plated terminals, RoHS-compliant, AEC-Q101 qualified. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode | Reverse-blocking / avalanche terminal | Connected to protected line (e.g., 5 V rail); color band identifies this end for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR and low leakage over lifetime, even under thermal cycling and humidity stress |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| 400 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth) on 12 V systems without failure |
| Low clamping ratio (VC/VBR ≈ 1.49) | Minimizes overvoltage stress on protected ICs - e.g., keeps 5 V logic inputs below absolute max rating during transients |
| Solderable per J-STD-002 | Compatible with standard SnPb and lead-free reflow profiles, including peak temps up to 260 °C |
Applications
| Automotive Sensor Protection | Industrial Power Input Stage |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., oxygen, pressure) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground, clamping negative transients and positive spikes above VWM. Use Value: Maintains signal integrity by limiting voltage excursions to ≤11.3 V, preventing latch-up or ESD damage to 5 V tolerant receivers. | Use Scenario: Safeguarding 5 V/12 V DC-DC converter inputs against inductive switching spikes from relays and solenoids. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main input rail, positioned upstream of bulk capacitor and controller IC. Use Value: Absorbs 400 W surges without degradation, enabling use of smaller input filter capacitors while meeting IEC 61000-4-4 immunity requirements. |
| Consumer USB Port Protection | Telecom Line Interface |
Use Scenario: Secondary protection on USB VBUS line after primary fuse and common-mode choke, guarding against hot-plug overshoot and ESD. IC Role / Device Role / Timing Role: Fast-response unidirectional suppressor tied between VBUS and GND, triggered only above 6.4 V. Use Value: Clamps 8 kV contact ESD (IEC 61000-4-2) to <12 V within <1 ns, preserving USB PHY functionality and avoiding system reset. | Use Scenario: Protecting RS-485 transceiver pins in building automation controllers exposed to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Rail-to-rail TVS on differential pair (A/B lines), referenced to local ground plane. Use Value: Limits transient common-mode voltage to ≤11.3 V, preventing damage to ±7 V-rated transceivers and maintaining data integrity during 1 kV surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package (SMB), 7.0 V VWM, 10.5 V VC at 34.4 A, same 400 W rating | Surface-mount footprint; higher thermal resistance (RθJA = 110 °C/W vs. 100 °C/W) | Select for automated SMT assembly where board space is constrained and thermal management allows. |
| 1.5KE7.5A | DO-201AD package, 7.5 V VWM, 12.0 V VC at 33.3 A, 1500 W peak rating | Higher power handling but larger size and slower response due to higher junction capacitance | Choose when protecting high-energy AC mains inputs or legacy designs requiring through-hole robustness. |
Compared with SMBJ7.0A and 1.5KE7.5A, P4KE7.5CHE3/54 offers optimal balance of axial-leaded reliability, AEC-Q101 compliance, and precise 6.40 V stand-off for 5 V system protection - making it preferred for automotive and industrial through-hole designs where qualification and thermal margin are critical.

FAQ
What is the polarity configuration of P4KE7.5CHE3/54?
P4KE7.5CHE3/54 is a unidirectional TVS diode: it blocks reverse voltage up to 6.40 V (VWM) and conducts in avalanche mode above 7.13–7.88 V (VBR). The cathode is marked by a color band on the DO-41 body - correct orientation is essential to protect positive-going transients on the cathode-connected line.
Does P4KE7.5CHE3/54 meet automotive qualification standards?
Yes, P4KE7.5CHE3/54 carries the HE3 suffix, confirming AEC-Q101 qualification per Rev. 16-Sep-2021 Vishay document 88365. This includes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - validating its use in engine control, body electronics, and ADAS subsystems.
What is the maximum clamping voltage of P4KE7.5CHE3/54 under surge conditions?
The maximum clamping voltage (VC) of P4KE7.5CHE3/54 is 11.3 V at 35.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across production lots and temperature range (-55 °C to +175 °C), ensuring predictable overvoltage limiting for protected 5 V circuits.
Can P4KE7.5CHE3/54 be used in bidirectional protection applications?
No - P4KE7.5CHE3/54 is unidirectional only. For bidirectional protection (e.g., AC lines or differential signals), Vishay specifies CA-suffix parts such as P4KE7.5CA. Using P4KE7.5CHE3/54 in reverse-biased AC applications would result in forward conduction and potential failure.
What soldering processes are compatible with P4KE7.5CHE3/54?
P4KE7.5CHE3/54 supports both wave and reflow soldering per J-STD-002. Its matte tin-plated leads withstand solder dip at 275 °C for 10 s (JESD 22-B106), and it is rated for lead-free reflow profiles with peak temperatures up to 260 °C - verified in Vishay document 88365.
