Product details
Overview
P6KE7.5C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal or power lines in sensitive electronics. It features a 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 53.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE7.5C-E3/73 datasheet, P6KE7.5C-E3/73 pinout, P6KE7.5C-E3/73 application, or P6KE7.5C-E3/73 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified transient protector for bi-directional signal lines where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.45), and DO-15 package compatibility are critical selection criteria.
Technical Context
The P6KE7.5C-E3/73 operates as a bi-directional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response to ESD and lightning-induced transients. Its symmetrical V-I characteristics enable identical clamping behavior in both polarities, eliminating polarity marking requirements and simplifying layout in AC-coupled or differential bus applications.
It delivers 600 W peak pulse power handling per 10/1000 μs waveform with thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), supporting reliable operation up to 175 °C junction temperature. The device exhibits 0.061 %/°C temperature coefficient of VBR, ensuring stable breakdown across automotive temperature ranges.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine control units exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Bi-directional TVS placed between signal line and ground to clamp ±200 V transients within <1 ns. Use Value: Prevents damage to 12-bit ADC inputs and op-amp front-ends by limiting voltage to ≤11.3 V during 53.1 A surges. |
Use Scenario: Safeguarding RS-485 transceiver data lines in factory automation PLCs subjected to EFT bursts and ground potential differences. IC Role / Device Role / Timing Role: Paired across differential pair (A–GND and B–GND) to suppress common-mode transients up to 600 W. Use Value: Maintains signal integrity by holding clamping ratio below 1.5× VBR, avoiding false logic transitions during EMC testing. |
| Consumer Power Adapter Input | Telecom Line Card Surge Protection |
|
Use Scenario: Secondary-side transient suppression on 5 V/12 V DC outputs of wall adapters vulnerable to capacitor discharge events. IC Role / Device Role / Timing Role: Shunt-connected between VOUT and GND to absorb 10/1000 μs surges induced by hot-plug or cable coupling. Use Value: Limits output overshoot to 11.3 V, preventing latch-up in downstream USB controllers and LDOs. |
Use Scenario: Primary protection for Ethernet PHY interfaces on telecom line cards facing lightning-induced surges on twisted-pair cables. IC Role / Device Role / Timing Role: First-stage clamp ahead of gas discharge tube (GDT), reducing let-through voltage to secondary protectors. Use Value: Low VC/VBR ratio ensures GDT triggers only above 15 V, extending system-level surge endurance beyond 6 kV. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | DO-214AA package; 7.0 V VWM, 11.2 V VC at 53.3 A; 600 W rating; surface-mount | Requires PCB rework for SMT vs. through-hole; better high-frequency impedance but lower thermal mass | Select when board space is constrained and automated assembly is required; verify pad thermal relief for 175 °C operation |
| 1.5KE7.5C | Same DO-15 package; 7.5 V VWM, 12.0 V VC at 50 A; 1500 W rating; higher power but larger VC | Over-spec'd for 600 W needs; higher clamping voltage reduces margin for 5 V logic rails | Choose only if legacy 1.5KE footprint reuse is mandatory; otherwise P6KE7.5C-E3/73 offers tighter VC and lower cost |
Compared with SMBJ7.0CA and 1.5KE7.5C, the P6KE7.5C-E3/73 provides optimal balance of clamping precision (11.3 V), through-hole manufacturability, and AEC-Q101 qualification - making it preferred for new automotive and industrial designs where VC headroom and qualification traceability are decisive.

FAQ
What is the polarity configuration of P6KE7.5C-E3/73?
The P6KE7.5C-E3/73 is a bi-directional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode marking and functions identically regardless of terminal orientation - ideal for AC-coupled or differential signal lines where polarity cannot be guaranteed during installation or maintenance.
Does P6KE7.5C-E3/73 meet AEC-Q101 requirements?
Yes, the P6KE7.5C-E3/73 carries the HE3 suffix variant (P6KE7.5CHE3/73) for AEC-Q101 qualification. While the E3/73 version is RoHS-compliant and commercial-grade, the HE3/73 variant undergoes full stress testing per AEC-Q101 including HTGB, TCT, and ESD - confirming suitability for automotive under-hood applications.
What is the maximum clamping voltage of P6KE7.5C-E3/73 under surge conditions?
The P6KE7.5C-E3/73 clamps to a maximum of 11.3 V when subjected to its rated 53.1 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can P6KE7.5C-E3/73 be used in place of uni-directional P6KE7.5A?
No - P6KE7.5C-E3/73 is bi-directional and lacks polarity marking, while P6KE7.5A is uni-directional with cathode band. Substituting them requires circuit review: P6KE7.5C-E3/73 may be used on AC or floating lines, but not in DC circuits where forward conduction must be blocked - doing so risks unintended conduction during normal operation.
What is the thermal resistance specification for P6KE7.5C-E3/73?
The P6KE7.5C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W at TA = 25 °C. These values govern derating curves in Fig. 2 and Fig. 5 of the datasheet and must be applied when estimating safe operating area under repetitive surge conditions.
