Product details
Overview
P6KE7.5CA-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 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 at rated IPPM - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE7.5CA-E3/54 datasheet, P6KE7.5CA-E3/54 pinout, P6KE7.5CA-E3/54 application, or P6KE7.5CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status (not applicable to E3 suffix), and thermal resistance (RθJL = 20 °C/W) for board-level surge protection design.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both polarities, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive 10/1000 μs pulses at 0.01% duty cycle.
Designed for transient immunity in unregulated DC lines and low-speed signal paths, it delivers fast response time (<1 ns), low leakage (<500 μA at VWM), and thermal stability up to TJ = 175 °C. The DO-15 package supports manual or wave soldering (275 °C max, 10 s) and meets UL 94 V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 7.13 V / 7.88 V at IT = 10 mA - defines reliable conduction onset window for bidirectional clamping |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage exceeds 500 μA |
| VC @ IPPM | 11.3 V at 53.1 A - clamped voltage seen by protected circuit during worst-case 600 W transient |
| PPPM | 600 W (10/1000 μs waveform) - surge energy handling capacity per single event |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pour sizing |
| TJ range | −55 °C to +175 °C - operational and storage temperature envelope for under-hood and industrial environments |
| Package | DO-15 (DO-204AC) - industry-standard axial-leaded package with 0.242–0.258 inch body length |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional types; case diameter 0.130–0.138 inch, lead length ≥1.0 inch, body length 0.242–0.258 inch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | No functional distinction - either end connects to line or ground; clamps ± transients equally |
| Lead 1 / Lead 2 | Current path terminals | Leads serve as thermal and electrical interface; RθJL = 20 °C/W assumes full lead contact to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable VBR tolerance (±5%) and long-term reliability under thermal cycling |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) in properly decoupled circuits |
| Very fast response time (<1 ns) | Clamps transients before downstream CMOS inputs reach destructive voltage thresholds |
| AEC-Q101 qualified variant available (HE3 suffix) | P6KE7.5CA-HE3/54 meets automotive stress testing; E3 suffix is commercial-grade only |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosure-constrained industrial or telecom equipment |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and inductive switching spikes in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between signal line and chassis ground, absorbing ±100 V/50 A transients. Use Value: Prevents latch-up or gate oxide rupture in front-end op-amps and transceivers while maintaining signal integrity below 11.3 V clamping threshold. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise in factory automation cabinets. IC Role / Device Role / Timing Role: Line-to-ground TVS on 24 V DC discrete input channels, triggered within <1 ns to limit transient overvoltage. Use Value: Enables >100,000 actuation cycles without degradation, verified per IEC 61000-4-4 EFT immunity requirements. |
| Consumer Power Adapter Input | Telecom Line Interface |
Use Scenario: Secondary-side transient suppression on 5–12 V DC outputs of wall adapters subjected to lightning-induced surges via shared AC mains. IC Role / Device Role / Timing Role: Bidirectional clamp across output rails to suppress common-mode and differential transients entering connected devices. Use Value: Limits output overvoltage to ≤11.3 V during 600 W events, preventing damage to USB-C PD controllers and PMICs. | Use Scenario: Protection of RS-232/RS-485 transceiver pins in network edge devices connected to unshielded wiring in building infrastructure. IC Role / Device Role / Timing Role: Point-of-entry TVS on each data line referenced to local ground, handling ±15 kV HBM ESD and 1 kV ring-wave surges. Use Value: Maintains signal eye diagram integrity by clamping transients before receiver input stages exceed absolute maximum ratings. |
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 VWM, 600 W PPPM, lower RθJA (50 °C/W vs. 75 °C/W) | Surface-mount alternative with higher board density; requires reflow profile validation | Select when automated assembly and space constraints outweigh through-hole serviceability needs |
| 1.5KE7.5CA | Same DO-15 package, 7.5 V VWM, but 1500 W PPPM and higher IPPM (123 A) | Higher-energy surge handling for primary-side AC input protection or harsher industrial environments | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 or requires margin beyond 600 W |
Compared with SMBJ7.0CA and 1.5KE7.5CA, P6KE7.5CA-E3/54 offers optimal cost-performance balance for secondary-side DC line protection where 600 W clamping and DO-15 through-hole mounting are sufficient - avoiding over-engineering while ensuring AEC-Q101-compatible variants exist for automotive derivatives.

FAQ
What does the "CA" suffix indicate in P6KE7.5CA-E3/54?
The "CA" suffix denotes a bidirectional configuration: P6KE7.5CA-E3/54 clamps voltage transients of either polarity symmetrically, unlike unidirectional "A" variants that conduct only in reverse bias. This makes P6KE7.5CA-E3/54 ideal for AC-coupled or floating signal lines where polarity is undefined or reversible, such as RS-485 buses or transformer-isolated interfaces.
Is P6KE7.5CA-E3/54 AEC-Q101 qualified?
No - P6KE7.5CA-E3/54 carries the "E3" suffix, indicating RoHS-compliant commercial grade per JESD 201 Class 1A whisker testing. For AEC-Q101 qualification, the correct part is P6KE7.5CA-HE3/54 (HE3 suffix). Both share identical electrical specs and DO-15 packaging, but only HE3 undergoes automotive stress testing including temperature cycling and humidity bias HAST.
What is the maximum clamping voltage of P6KE7.5CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE7.5CA-E3/54 is 11.3 V at its rated peak pulse current (IPPM) of 53.1 A, measured with a 10/1000 μs waveform. This value represents the upper voltage limit imposed on protected circuitry during a full 600 W transient event, ensuring downstream components remain within safe operating area.
Can P6KE7.5CA-E3/54 be used in place of a unidirectional TVS like P6KE7.5A?
P6KE7.5CA-E3/54 can replace P6KE7.5A only if bidirectional clamping is required and circuit topology allows symmetrical protection - e.g., across differential pairs or isolated grounds. It must not be substituted in unidirectional applications with cathode-anode polarity dependence (e.g., DC power rail to ground), as P6KE7.5CA-E3/54 lacks defined polarity and will conduct in both directions.
What is the thermal resistance from junction to ambient for P6KE7.5CA-E3/54?
The typical junction-to-ambient thermal resistance (RθJA) for P6KE7.5CA-E3/54 is 75 °C/W under standard JEDEC test conditions (single device on FR-4, 1 in² copper pad). Actual RθJA in end equipment depends on PCB layout: doubling copper area reduces it by ~20%, while adding internal ground planes further improves heat dissipation for repeated surge events.
