Product details
Overview
P4KE7.5A-E3/53 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 7.13 V to 7.88 V breakdown voltage (VBR) at 10 mA, 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 interfaces and industrial I/O protection.
For engineers reviewing the P4KE7.5A-E3/53 datasheet, P4KE7.5A-E3/53 pinout, P4KE7.5A-E3/53 application, or P4KE7.5A-E3/53 equivalent, key selection criteria include verified clamping performance under 35.4 A surge, unidirectional polarity marking (cathode band), DO-41 mechanical compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, it avalanches into low-impedance conduction to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<500 µA at 6.40 V).
The device sustains 40 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 0.061 %/°C temperature coefficient of VBR, and maintains thermal resistance of 66 °C/W (junction-to-lead), enabling reliable operation up to +175 °C junction temperature in constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - defines precise avalanche initiation window for predictable clamping onset |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage rises above 500 µA |
| VC @ IPPM | 11.3 V at 35.4 A - clamping voltage during 400 W transient, limiting protected IC stress to safe margin |
| PPPM | 400 W - peak pulse power handling per 10/1000 µs waveform, supporting IEC 61000-4-5 Level 3 surges |
| IFSM | 40 A - single 8.3 ms surge current capability, sufficient for inductive switch-off transients in 12 V systems |
| TJ max. | +175 °C - high-temperature operation enables placement near heat sources without derating loss |
| RθJL | 66 °C/W - low junction-to-lead thermal resistance supports sustained power dissipation in DO-41 package |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; matte tin-plated terminals solderable per J-STD-002; cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode | Avalanche conduction terminal | Marked end; connected to protected line (e.g., 5 V rail or CAN_H) to clamp positive transients |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance and long-term leakage stability under thermal cycling |

| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including engine control modules and body electronics |
| Low clamping ratio (VC/VBR ≈ 1.49) | Minimizes overvoltage stress on downstream MOSFETs or microcontrollers during surge events |
| UL 94 V-0 compliant molding compound | Supports safety-critical designs requiring flame-retardant enclosure integration |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in 12 V vehicle subsystems from load-dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between sensor signal line and ground to clamp positive spikes before reaching ADC input. Use Value: Clamps 35.4 A surge to ≤11.3 V, preventing damage to 5 V-tolerant op-amps and ensuring signal integrity during cranking events. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to field wiring inductive kickback. IC Role / Device Role / Timing Role: Primary-level TVS on 24 V DC input terminals to absorb repetitive switching surges from solenoid valves and contactors. Use Value: Withstands 400 W pulses at 0.01% duty cycle and maintains <500 µA leakage at 6.40 V, preserving input threshold accuracy over time. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for USB-C PD and fast-charging devices. IC Role / Device Role / Timing Role: Unidirectional TVS across 5 V/9 V/15 V output rails to suppress flyback transformer ringing and ESD coupling. Use Value: Fast response time and 11.3 V clamping limit output overshoot below IC absolute maximum ratings during no-load transient conditions. |
Use Scenario: Front-end protection of Ethernet PHY or RS-485 transceivers connected to external cabling subject to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage TVS on differential pair (e.g., TX+/TX−) referenced to chassis ground to shunt common-mode transients. Use Value: 66 °C/W thermal resistance allows direct mounting on PCB without heatsink while sustaining repeated 10/1000 µs surges per GR-1089-CORE. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package; 7.0 V VWM, 10.5 V VC @ 34.4 A; 600 W PPPM | Higher power rating but larger footprint; surface-mount only | Select when board space permits SMD layout and higher surge margin is required beyond 400 W |
| 1.5KE7.5A | DO-201AD package; identical VBR/VWM/VC; 1500 W PPPM; 200 A IPPM | Higher surge capacity but longer lead inductance; through-hole with larger body | Choose for legacy through-hole designs needing >400 W headroom or where DO-41 mechanical constraints limit mounting density |
Compared with SMBJ7.0A and 1.5KE7.5A, the P4KE7.5A-E3/53 offers optimal balance of DO-41 axial fit, AEC-Q101 qualification, and 400 W surge capability - making it preferred for cost-sensitive, space-constrained automotive and industrial through-hole protection where 35.4 A clamping suffices.

FAQ
What is the breakdown voltage range of the P4KE7.5A-E3/53?
The P4KE7.5A-E3/53 has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in 5 V and 6 V systems where the P4KE7.5A-E3/53 is commonly deployed.
Is the P4KE7.5A-E3/53 suitable for automotive applications?
Yes, the P4KE7.5A-E3/53 is AEC-Q101 qualified when ordered with the HE3 suffix (e.g., P4KE7.5AHE3/53); however, the E3 suffix variant (P4KE7.5A-E3/53) is commercial-grade and RoHS-compliant but not AEC-Q101 certified. For automotive use, confirm ordering code and qualification status - the P4KE7.5A-E3/53 itself meets all electrical specs but lacks formal automotive qualification documentation unless specified as HE3.
What does the "-E3/53" suffix indicate in P4KE7.5A-E3/53?
The "-E3" denotes RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, while "/53" specifies packaging in 5500-piece 13-inch paper tape and reel. This format aligns with Vishay's standard ordering nomenclature for DO-41 TVS diodes and ensures compatibility with automated through-hole insertion equipment and traceable logistics handling.
How does the clamping voltage of P4KE7.5A-E3/53 compare to its breakdown voltage?
The P4KE7.5A-E3/53 clamps at 11.3 V when subjected to its rated 35.4 A peak pulse current (10/1000 µs), yielding a clamping ratio (VC/VBR) of approximately 1.49 using the nominal VBR of 7.58 V. This ratio reflects efficient avalanche conduction and low dynamic impedance, critical for protecting 5 V logic interfaces without exceeding absolute maximum ratings of downstream ICs.
Can P4KE7.5A-E3/53 be used in bidirectional configurations?
No - the P4KE7.5A-E3/53 is strictly unidirectional, identified by a cathode band. Bidirectional variants require the "CA" suffix (e.g., P4KE7.5CA). Using the P4KE7.5A-E3/53 in reverse-biased AC applications would result in forward conduction during negative half-cycles, causing failure. Always verify polarity marking and select CA-series parts for symmetrical transient suppression.
