Product details
Overview
P6KE7.5CA-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 7.13–7.88 V breakdown voltage at 10 mA test current, and clamps to ≤11.3 V at 53.1 A peak pulse current. Used in automotive sensor interfaces and industrial I/O protection where bidirectional surge immunity is required.
For engineers reviewing the P6KE7.5CA-E3/73 datasheet, P6KE7.5CA-E3/73 pinout, P6KE7.5CA-E3/73 application, or P6KE7.5CA-E3/73 equivalent, this page delivers verified electrical specs, DO-15 terminal mapping, real-world clamping behavior, and qualified alternatives for ESD/lightning transient protection in bidirectional AC-coupled or floating circuits.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical avalanche conduction in both polarities. Its glass-passivated junction enables fast response (<1 ns) and low dynamic impedance under surge conditions, while the DO-15 package supports lead-free soldering per J-STD-002 and withstands 275 °C dip for 10 s.
Rated for -55 °C to +175 °C junction temperature, it delivers 600 W peak pulse power with 0.01 % duty cycle and exhibits a 0.061 %/°C temperature coefficient of breakdown voltage - critical for stable clamping across thermal operating ranges in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 7.13–7.88 V at 10 mA - defines minimum voltage at which avalanche conduction begins in either direction |
| Stand-off Voltage VWM | 6.40 V - maximum continuous reverse voltage before leakage exceeds 500 μA |
| Clamping Voltage VC | ≤11.3 V at 53.1 A IPPM - limits transient voltage seen by downstream circuitry during 10/1000 μs surge |
| Peak Pulse Power PPPM | 600 W - energy-handling capability for standardized lightning/surge waveforms without failure |
| Maximum Leakage ID | 500 μA at 6.40 V - ensures minimal standby current draw in always-on sensing circuits |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in under-hood automotive and high-ambient industrial locations |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case with matte tin-plated leads. RoHS-compliant, commercial grade (E3 suffix), UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (bidirectional) | Non-polarized terminals | No marking; symmetrical conduction - either lead serves as input/output for transient suppression in AC or floating DC paths |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω) without derating in compact layouts |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress, unlike epoxy-passivated alternatives |
| AEC-Q101 qualified variant available (HE3) | Validates suitability for automotive electronics where qualification beyond commercial grade is mandatory |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes overvoltage exposure to protected ICs - critical for 3.3 V or 5 V logic interfacing |
Applications
| Automotive Sensor Interface | Industrial Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed across differential or single-ended signal lines upstream of the receiver input. Use Value: Limits transient voltage to ≤11.3 V, preventing latch-up or gate oxide damage in 5 V tolerant transceivers while maintaining signal integrity below VWM. |
Use Scenario: Safeguarding 4–20 mA current loop receivers and ADC front-ends in PLC analog input modules exposed to field wiring surges. IC Role / Device Role / Timing Role: Parallel-connected TVS on each analog input channel, referenced to system ground or isolated common. Use Value: Clamps 600 W surges within nanoseconds, preserving measurement accuracy by avoiding saturation of op-amp input stages during transient events. |
| Consumer Audio Line Protection | Telecom DSL/ADSL Line Interface |
Use Scenario: Shielding line-in/line-out jacks on AV receivers and soundbars from ESD and cable-induced transients during hot-plug events. IC Role / Device Role / Timing Role: Bidirectional TVS placed between unbalanced audio conductors (tip/ring) and chassis ground. Use Value: Withstands ±15 kV contact ESD (IEC 61000-4-2) and clamps induced spikes to <12 V, preventing pop-noise or amplifier shutdown. |
Use Scenario: Front-end protection for ADSL splitter and line driver ICs in customer-premises equipment subjected to lightning-induced longitudinal surges. IC Role / Device Role / Timing Role: Paired P6KE7.5CA-E3/73 devices across tip-ring and tip-ground/ring-ground in hybrid coupler interface. Use Value: Symmetrical clamping maintains balanced line integrity while diverting >50 A surges away from sensitive xDSL PHYs without polarity bias. |
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 rating, lower RθJA (50 °C/W) | Better thermal performance in surface-mount layouts; requires PCB rework for through-hole replacement | Select when board space is constrained and SMT assembly is preferred over axial-leaded DO-15 |
| P6KE7.5A-E3/73 | Unidirectional version; same VBR, VC, and PPPM but asymmetric conduction (cathode-marked) | Required only for DC-biased lines where reverse polarity must be blocked, not clamped | Choose only if circuit topology mandates unidirectional clamping - otherwise P6KE7.5CA-E3/73 provides broader protection coverage |
Compared with SMBJ7.0CA and P6KE7.5A-E3/73, the P6KE7.5CA-E3/73 offers native bidirectional protection in a proven through-hole package ideal for prototyping, high-vibration environments, and legacy designs - without requiring layout changes or polarity-aware placement.

FAQ
What is the key difference between P6KE7.5CA-E3/73 and P6KE7.5A-E3/73?
The P6KE7.5CA-E3/73 is bidirectional - it clamps voltage transients equally in both polarities with no polarity marking. The P6KE7.5A-E3/73 is unidirectional, featuring a cathode band and conducting only in reverse bias. This makes P6KE7.5CA-E3/73 suitable for AC-coupled, floating, or differential signal lines where polarity is undefined, while P6KE7.5A-E3/73 applies to DC-biased circuits needing forward blocking.
Does P6KE7.5CA-E3/73 meet AEC-Q101 qualification?
No - the P6KE7.5CA-E3/73 carries the E3 suffix, indicating RoHS-compliant commercial grade. For AEC-Q101 qualification, select the HE3-suffixed variant (e.g., P6KE7.5CAHE3/73), which undergoes extended stress testing for automotive under-hood use. The P6KE7.5CA-E3/73 remains appropriate for non-automotive industrial and consumer applications.
What is the maximum clamping voltage of P6KE7.5CA-E3/73 under surge conditions?
The P6KE7.5CA-E3/73 clamps to a maximum of 11.3 V when subjected to its rated peak pulse current of 53.1 A (10/1000 μs waveform). This value is guaranteed per the Vishay datasheet and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events.
Can P6KE7.5CA-E3/73 be used in place of a unidirectional TVS in a DC power rail?
Yes, but with caution: the P6KE7.5CA-E3/73 will conduct during both positive and negative excursions, so it is safe on floating or AC rails. On a DC rail with defined polarity, it may short reverse-biased transients - acceptable if the rail can tolerate brief bidirectional conduction. For strict DC polarity control, the unidirectional P6KE7.5A-E3/73 is preferred.
What is the thermal resistance of P6KE7.5CA-E3/73, and how does it affect layout?
The P6KE7.5CA-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. To maintain reliability under repetitive surges, minimize trace length to copper pour and ensure ≥25 mm² of 1 oz. copper connected to each lead - especially critical in high-duty-cycle industrial applications where self-heating impacts clamping stability.
