Product details
Overview
P6KE7.5A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on power and signal 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, 500 A maximum peak pulse current, and 11.3 V clamping voltage at IPPM - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the P6KE7.5A-E3/54 datasheet, P6KE7.5A-E3/54 pinout, P6KE7.5A-E3/54 application, or P6KE7.5A-E3/54 equivalent, this page delivers verified electrical parameters, DO-15 terminal mapping, real-world clamping behavior, thermal derating curves, and qualified AEC-Q101 alternatives - all aligned to Vishay Document #88369 (Rev. 27-Sep-2021).
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below 6.40 V (VWM), triggers avalanche conduction at 7.13–7.88 V (VBR), and limits transient excursions to ≤11.3 V at 500 A (VC). Its glass-passivated junction enables sub-nanosecond response and low incremental surge resistance.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); power dissipation is rated at 5.0 W on infinite heatsink (TL = 75 °C), with full derating above TA = 25 °C per Figure 2. The device meets JESD 22-B106 solder dip (275 °C, 10 s) and JESD 201 Class 1A whisker test requirements.
Key Specifications

|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., oxygen, pressure) from load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Shunt clamping element placed between signal line and ground, triggered within nanoseconds of overvoltage onset. Use Value: Limits transient voltage to 11.3 V, preventing damage to 5 V tolerant transceivers and preserving signal integrity during 12 V/24 V system faults. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Standoff voltage (6.40 V) blocks normal 5 V/24 V logic levels; clamps >7.13 V transients to protect microcontroller GPIOs. Use Value: Withstands 500 A surges while maintaining <11.3 V clamping - avoids false triggering and ensures deterministic reset behavior after surge events. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
|
Use Scenario: Secondary-side DC output protection in wall adapters subjected to capacitor discharge and hot-plug transients. IC Role / Device Role / Timing Role: Unidirectional shunt connected across +VOUT and GND, absorbing energy from capacitive coupling and ESD events. Use Value: 600 W rating handles repetitive 10/1000 μs surges up to 0.01% duty cycle - extends adapter lifetime in shared-socket environments. |
Use Scenario: Overvoltage suppression on Ethernet PHY power rails (e.g., 3.3 V bias for magnetics) in PoE-powered devices. IC Role / Device Role / Timing Role: Clamping diode referenced to local ground plane, activated only during fast-rising common-mode surges. Use Value: 7.13–7.88 V VBR aligns with 3.3 V rail tolerance margins; 11.3 V VC prevents latch-up in Gigabit PHYs during lightning-induced surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package; 7.0 V VWM, 7.78–8.6 V VBR, 12.0 V VC @ 44.8 A - lower IPPM but surface-mount compatible | Preferred for space-constrained PCBs where reflow assembly replaces through-hole; not suitable for high-current (>100 A) surge scenarios | Select SMBJ7.0A when board area is limited and peak surge current remains ≤45 A; verify thermal relief pad design for 5.0 W dissipation. |
| P6KE7.5CA | Bidirectional variant; same VBR range (7.13–7.88 V), symmetric clamping (11.3 V both polarities), no polarity marking | Required for AC-coupled or differential signal lines (e.g., RS-485, audio) where negative transients must also be suppressed | Choose P6KE7.5CA only when protecting bidirectional signals; note that unidirectional P6KE7.5A-E3/54 offers superior cost and layout simplicity for DC rails. |
Compared with SMBJ7.0A and P6KE7.5CA, the P6KE7.5A-E3/54 delivers higher surge current handling (500 A vs. 44.8 A) in a through-hole package ideal for prototyping and high-energy industrial inputs, while retaining compatibility with legacy DO-15 footprints and AEC-Q101-qualified variants.

FAQ
What is the clamping voltage of the P6KE7.5A-E3/54 under maximum surge conditions?
The P6KE7.5A-E3/54 clamps to 11.3 V when subjected to its rated 500 A peak pulse current (10/1000 μs waveform), as specified in Vishay Document #88369. This value represents the maximum voltage seen across the device during worst-case transient events and directly determines the overvoltage stress imposed on downstream components like microcontrollers or transceivers. The clamping performance is validated at TA = 25 °C and derates predictably with junction temperature rise.
Is the P6KE7.5A-E3/54 suitable for automotive applications?
Yes - the P6KE7.5A-E3/54 is RoHS-compliant and offered in an AEC-Q101-qualified variant (P6KE7.5AHE3/54). While the E3 suffix denotes commercial grade, the HE3 version undergoes stress testing per AEC-Q101 including temperature cycling, humidity bias, and high-temperature operating life. For automotive use, specify HE3 and confirm mounting configuration meets thermal requirements per Figure 5 derating curve.
How does the P6KE7.5A-E3/54 differ from bidirectional TVS diodes like P6KE7.5CA?
The P6KE7.5A-E3/54 is unidirectional, meaning it conducts only when cathode voltage exceeds anode by ≥7.13 V - ideal for DC power rails and single-polarity signal lines. In contrast, P6KE7.5CA provides symmetrical clamping for both polarities, required for AC or differential signals. The unidirectional P6KE7.5A-E3/54 offers tighter VBR tolerance and simpler layout (cathode marking), while P6KE7.5CA eliminates polarity concerns at the cost of slightly higher capacitance.
What is the maximum continuous power dissipation for the P6KE7.5A-E3/54?
The P6KE7.5A-E3/54 has a steady-state power dissipation rating of 5.0 W when mounted on an infinite heatsink at TL = 75 °C (per Figure 5). In typical PCB applications without heatsinking, derating applies: at TA = 25 °C, the device supports ~3.8 W; at TA = 70 °C, usable power drops to ~1.5 W. This rating governs long-term leakage-related heating, not transient surge absorption.
Can the P6KE7.5A-E3/54 replace older P6KE7.5A parts without layout changes?
Yes - the P6KE7.5A-E3/54 uses the standard DO-15 (DO-204AC) package with identical mechanical dimensions, lead spacing, and soldering specifications as legacy P6KE7.5A variants. The "E3/54" suffix indicates RoHS-compliant matte tin plating and 13-inch paper tape/reel packaging (4000 units per reel), fully compatible with existing through-hole assembly processes and footprint libraries.
