Product details
Overview
P6KE75CA-E3/54 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 71.3 V minimum breakdown voltage (VBR), 64.1 V standoff voltage (VWM), 103 V maximum clamping voltage at 5.8 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE75CA-E3/54 datasheet, P6KE75CA-E3/54 pinout, P6KE75CA-E3/54 application, or P6KE75CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low incremental surge resistance, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a voltage-clamping protection element in both polarities, with symmetrical electrical characteristics across anode and cathode terminals. Its glass-passivated junction enables fast response time (<1 ns) and stable clamping under repetitive 10/1000 μs surges at 0.01% duty cycle.
Thermal performance is defined by 20 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient resistance, supporting operation from –55 °C to +175 °C. The 5.0 W steady-state power dissipation (PD) and 100 A non-repetitive forward surge rating (IFSM) apply only to unidirectional variants - not applicable to P6KE75CA-E3/54 due to its bidirectional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - maximum continuous reverse working voltage before leakage exceeds 1 μA; defines safe operating margin below clamping threshold |
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA test current - ensures reliable conduction onset during overvoltage events without premature triggering |
| VC @ IPPM | 103 V at 5.8 A - clamped voltage seen by protected circuit during full-rated 600 W transient; limits stress on downstream components |
| PPPM | 600 W - peak pulse power handling per 10/1000 μs waveform; validates robustness against lightning-induced or inductive-switching surges |
| TJ max | +175 °C - maximum junction temperature; supports high-temperature environments including engine bay and power supply sections |
| Package | DO-15 (DO-204AC) - industry-standard axial-leaded package with 0.242–0.258 inch body length; compatible with through-hole assembly and manual rework |
| AEC-Q101 | Qualified - certified for automotive applications per stress-test requirements including temperature cycling, HTRB, and ESD; HE3 suffix required for qualification, but E3 suffix indicates RoHS-compliant commercial grade |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; no polarity marking on bidirectional devices - terminals are functionally symmetric and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

|---|---|
|
Use Scenario: Suppresses load-dump and jump-start transients on 12 V battery-fed ECUs and body control modules. IC Role / Device Role / Timing Role: Bidirectional clamping TVS placed between power rail and ground, acting as first-line overvoltage shunt. Use Value: Limits rail voltage to ≤103 V during 600 W surges, preventing damage to 3.3 V/5 V microcontrollers and CAN transceivers. |
Use Scenario: Shields analog and digital signal lines (e.g., LIN, PWM, thermistor inputs) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor mounted directly at connector entry point to minimize stub inductance. Use Value: Clamps ±15 kV contact ESD (IEC 61000-4-2) within nanoseconds while adding <1 pF parasitic capacitance to signal path. |
| Telecom Power Supply Input | Consumer Appliance Motor Drive Protection |
|
Use Scenario: Protects AC/DC adapter primary-side rectifier and secondary-side DC bus from lightning-induced surges (IEC 61000-4-5). IC Role / Device Role / Timing Role: High-power TVS connected across bulk capacitor input to clamp differential-mode transients before regulation stage. Use Value: Absorbs 600 W pulses without degradation, maintaining system uptime in outdoor telecom cabinets exposed to grid instability. |
Use Scenario: Guards H-bridge gate drivers and current-sense amplifiers against back-EMF spikes from brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Bidirectional suppressor placed across motor terminals or between driver output and ground. Use Value: Clamps inductive kickback to ≤103 V, eliminating false triggering of overvoltage protection and extending MOSFET lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | DO-214AA package (SMB), 75 V VWM, 100 V VC @ 6.5 A, same 600 W rating | Surface-mount footprint; higher IPPM but larger board area than DO-15; better thermal coupling to PCB copper | Select when automated SMT assembly is preferred and layout allows SMB footprint; verify creepage/clearance for high-voltage isolation |
| 1.5KE75CA | DO-201AD package, 75 V VWM, 108 V VC @ 5.6 A, 1500 W rating (10/1000 μs) | Higher power rating and larger case; requires more board space and higher mounting torque for axial leads | Choose for legacy designs requiring higher surge margin or where existing 1.5KE footprint is standardized |
Compared with P6KE75CA-E3/54, SMBJ75CA offers SMT compatibility and slightly tighter clamping but demands PCB redesign, while 1.5KE75CA delivers 2.5× peak power at the cost of larger DO-201AD form factor - making P6KE75CA-E3/54 optimal for cost-sensitive through-hole applications needing AEC-Q101-aligned reliability in compact DO-15.

FAQ
What is the clamping voltage of P6KE75CA-E3/54 at its rated peak pulse current?
The P6KE75CA-E3/54 has a maximum clamping voltage (VC) of 103 V when subjected to its rated peak pulse current of 5.8 A using the standard 10/1000 μs waveform. This value is measured under specified test conditions per Vishay Document 88369 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The P6KE75CA-E3/54 maintains this clamping performance consistently across its operational temperature range.
Is P6KE75CA-E3/54 qualified to AEC-Q101?
No - P6KE75CA-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial-grade construction. AEC-Q101 qualification applies only to parts with the HE3 suffix (e.g., P6KE75CAHE3/54). While the P6KE75CA-E3/54 shares identical electrical and mechanical specifications with its HE3 counterpart, it has not undergone the extended stress testing required for automotive qualification. For AEC-Q101 compliance, specify P6KE75CAHE3/54.
What does the "CA" suffix mean in P6KE75CA-E3/54?
The "CA" suffix in P6KE75CA-E3/54 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse directions. Unlike unidirectional P6KE75A variants, which have a cathode band and conduct only in one polarity, the CA version has no polarity marking and functions identically regardless of terminal orientation. This makes P6KE75CA-E3/54 ideal for AC-coupled lines or differential signal protection where polarity cannot be guaranteed.
Can P6KE75CA-E3/54 replace P6KE75A in an existing design?
P6KE75CA-E3/54 can replace P6KE75A only if the circuit requires bidirectional clamping and the physical layout accommodates non-polarized placement. Since P6KE75A is unidirectional (cathode-marked), substituting the CA variant removes polarity dependency but may alter leakage behavior above VWM due to dual-junction symmetry. Review system-level surge testing after substitution, especially in DC-biased rails where unidirectional blocking is relied upon. The P6KE75CA-E3/54 is not a drop-in replacement unless bidirectionality is explicitly required.
What is the maximum junction temperature rating for P6KE75CA-E3/54?
The P6KE75CA-E3/54 has a maximum junction temperature (TJ) rating of +175 °C, enabling reliable operation in high-temperature environments such as engine compartments, power supply heatsinks, and enclosed industrial enclosures. This rating is supported by its DO-15 package's 20 °C/W junction-to-lead thermal resistance and validated thermal derating curves in Vishay Document 88369. Derating begins above 25 °C ambient, and sustained operation near TJ max requires appropriate PCB copper area and airflow per Figure 5.
