Product details
Overview
P6KE7.5CAHE3/54 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, 6.40 V stand-off voltage, 53.1 A peak pulse current, and 11.3 V maximum clamping voltage - used to protect MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the P6KE7.5CAHE3/54 datasheet, P6KE7.5CAHE3/54 pinout, P6KE7.5CAHE3/54 application, or P6KE7.5CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, low clamping ratio (VC/VWM = 1.77), and 175 °C junction temperature rating.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 6.4 V), but switches to low-impedance conduction within <1 ns when transient voltage exceeds VBR. Its glass-passivated junction ensures stable avalanche characteristics and repeatable clamping performance across 1000+ surge events.
The bidirectional configuration enables symmetric suppression of positive and negative transients without polarity sensitivity - critical for AC-coupled signal lines and differential buses. Thermal resistance (RθJL = 20 °C/W) supports reliable operation up to 175 °C junction temperature with standard PCB copper land patterns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 7.13–7.88 V at 10 mA - defines precise turn-on threshold for transient clamping |
| Stand-off Voltage (VWM) | 6.40 V - maximum continuous working voltage before leakage exceeds 500 μA |
| Clamping Voltage (VC) | 11.3 V at 53.1 A IPPM - limits downstream voltage stress during worst-case surge |
| Peak Pulse Power (PPPM) | 600 W (10/1000 μs) - sustains industrial-grade lightning/surge immunity per IEC 61000-4-5 |
| Junction Temperature Range | −55 to +175 °C - enables deployment in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with 25.4 mm minimum lead length |
Pinout & Package
DO-15 (DO-204AC) package: axial-leaded, molded epoxy body, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Bidirectional construction means no polarity marking; both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Either terminal conducts during positive or negative overvoltage - no orientation required in layout |
| Lead 1 / Lead 2 | Thermal and electrical interface | Leads serve as primary heat path (RθJL = 20 °C/W); 0.375″ (9.5 mm) lead length specified for thermal derating curves |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable avalanche characteristics and long-term reliability under repetitive surge stress |
| 600 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 Level 4 (4 kV) surge immunity without external heatsinking |
| AEC-Q101 qualification | Validated for automotive powertrain and body control modules requiring extended temperature and life testing |
| Low clamping ratio (VC/VWM = 1.77) | Minimizes voltage overshoot during fast transients - critical for protecting 5 V logic and analog sensors |
| UL 94 V-0 molding compound | Provides flame-retardant enclosure suitable for enclosed industrial and automotive enclosures |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., oxygen, pressure) from load dump and inductive switching spikes in engine control units. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed directly across protected line and ground, responding in <1 ns. Use Value: Clamps 11.3 V at 53.1 A, preventing damage to 5 V tolerant receivers while maintaining signal integrity during ISO 7637-2 Pulse 5a events. |
Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers against field-wiring induced surges and relay contact bounce. IC Role / Device Role / Timing Role: Standoff-mode protector operating below 6.4 V, triggering only during >7.13 V transients on DC supply rails. Use Value: Withstands 600 W pulses without degradation, enabling compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity standards. |
| Consumer Power Adapter Input | Telecom Line Interface |
Use Scenario: Secondary-side overvoltage protection in AC/DC adapters for USB-C PD and smart home hubs exposed to mains-borne transients. IC Role / Device Role / Timing Role: Bidirectional clamp between VOUT and GND, absorbing energy from transformer leakage inductance spikes. Use Value: 175 °C max junction temperature allows operation in compact, thermally constrained enclosures without forced air cooling. |
Use Scenario: Primary protection for Ethernet PHY interfaces and RS-485 transceivers in network edge devices subjected to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: First-stage shunt element in multi-stage protection architecture, diverting >90 % of surge current before TVS arrays or GDTs. Use Value: Symmetric bidirectional response eliminates need for dual unidirectional devices, reducing BOM count and PCB area in space-constrained modules. |
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, 600 W rating, 7.0 V nominal VBR (min 6.65 V), 12.6 V VC at 47.6 A | Surface-mount alternative with lower profile; requires rework of footprint and thermal pad design | Select when board space is constrained and automated SMT assembly is preferred over through-hole |
| 1.5KE7.5CA | DO-201AD package, 1500 W rating, same VBR range (7.13–7.88 V), 12.0 V VC at 125 A | Higher power handling for severe surge environments; larger package and higher cost | Choose for applications requiring >1 kV IEC 61000-4-5 immunity where 600 W is insufficient |
Compared with P6KE7.5CAHE3/54, SMBJ7.0CA offers SMT compatibility at the expense of thermal mass and manual assembly flexibility, while 1.5KE7.5CA delivers 2.5× peak power in a larger axial package - making P6KE7.5CAHE3/54 optimal for cost-sensitive, AEC-Q101-compliant through-hole designs with moderate surge exposure.

FAQ
What does the "CA" suffix indicate in P6KE7.5CAHE3/54?
The "CA" suffix denotes a bidirectional configuration: P6KE7.5CAHE3/54 provides symmetrical clamping for both positive and negative voltage transients, unlike unidirectional variants (e.g., P6KE7.5A) that require correct polarity orientation. This makes P6KE7.5CAHE3/54 ideal for AC-coupled lines and differential interfaces where polarity is undefined or variable.
Is P6KE7.5CAHE3/54 suitable for automotive applications?
Yes - P6KE7.5CAHE3/54 carries AEC-Q101 qualification, confirming compliance with stress tests including high-temperature operating life, temperature cycling, and ESD robustness. Its −55 to +175 °C operating range and DO-15 mechanical stability make P6KE7.5CAHE3/54 appropriate for engine control, body electronics, and ADAS sensor protection.
How does the clamping voltage of P6KE7.5CAHE3/54 compare to its breakdown voltage?
P6KE7.5CAHE3/54 has a breakdown voltage range of 7.13–7.88 V at 10 mA and a maximum clamping voltage of 11.3 V at 53.1 A. This yields a clamping ratio (VC/VBRmin) of 1.58, indicating efficient voltage limiting - critical for safeguarding 5 V logic circuits where even brief overvoltage can cause latch-up or permanent damage.
What is the meaning of the "HE3/54" suffix in P6KE7.5CAHE3/54?
The "HE3" indicates RoHS-compliant, AEC-Q101-qualified construction with JESD 201 Class 2 whisker resistance; "/54" specifies packaging in 13″ paper tape and reel with 4000 units per reel. This distinguishes P6KE7.5CAHE3/54 from commercial-grade "E3" variants and confirms suitability for automotive production environments requiring full traceability and reliability assurance.
Can P6KE7.5CAHE3/54 be used in place of a unidirectional TVS like P6KE7.5A?
No - P6KE7.5CAHE3/54 is bidirectional and lacks polarity marking, whereas P6KE7.5A is unidirectional with cathode band identification. Substituting P6KE7.5CAHE3/54 for P6KE7.5A may compromise protection in DC-biased circuits where reverse conduction must be blocked. Always verify circuit topology: use P6KE7.5CAHE3/54 only where symmetric transient suppression is required.
