Product details
Overview
P6KE7.5CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 600 W peak pulse power rating (10/1000 μs), 7.13–7.88 V breakdown voltage at 10 mA, 6.40 V stand-off voltage, 53.1 A maximum peak pulse current, and 11.3 V clamping voltage at IPPM - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE7.5CHE3/73 datasheet, P6KE7.5CHE3/73 pinout, P6KE7.5CHE3/73 application, or P6KE7.5CHE3/73 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and DO-15 lead-form compatibility with legacy PCB footprints.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (<1 μA leakage at 6.40 V), then rapidly avalanches below 11.3 V when transient energy exceeds its 600 W rating. Its glass-passivated junction enables fast response (<1 ns) and stable breakdown characteristics across -55 °C to +175 °C junction temperature range.
Designed for single-pulse and low-duty-cycle surge events (0.01 % max repetitive rate), the P6KE7.5CHE3/73 relies on thermal mass of its leads for dissipation - with 5.0 W steady-state power rating at TL = 75 °C and 20 °C/W junction-to-lead thermal resistance. It is not rated for continuous forward conduction beyond 100 A surge (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 7.13 V / 7.88 V at 10 mA - defines minimum guaranteed avalanche onset and maximum variation band for production screening |
| VWM | 6.40 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below system rail |
| VC @ IPPM | 11.3 V at 53.1 A - clamping voltage seen by protected circuit during worst-case 600 W transient; determines stress on downstream ICs |
| IPPM | 53.1 A - peak current capability under standardized 10/1000 μs waveform; used to size series impedance and fuse coordination |
| PPPM | 600 W - transient energy handling capacity; defines immunity level against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges |
| TJ max | +175 °C - maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead; critical for estimating temperature rise during repeated transients |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0. Matte tin-plated leads, RoHS-compliant, AEC-Q101 qualified (HE3 suffix). Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to system ground or low-side reference; conducts during positive transients when cathode is biased above anode |
| Cathode | Avalanche clamping node | Connected to protected line (e.g., 5 V rail); clamps voltage to ≤11.3 V during overvoltage events by diverting surge current to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, repeatable breakdown voltage and long-term reliability under thermal cycling and humidity exposure |
| 600 W peak pulse power (10/1000 μs) | Provides robust protection against common automotive and industrial surge waveforms without derating at room temperature |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.48) | Minimizes overvoltage stress on protected ICs while maintaining sufficient margin above VWM = 6.40 V |
| Solder dip rated 275 °C for 10 s | Supports standard wave soldering processes without degradation of electrical parameters or mechanical integrity |
Applications
| Automotive Sensor Interface | Industrial PLC Digital Input |

Use Value: Withstands multiple 10/1000 μs surges up to 53.1 A without parameter shift, ensuring long-term reliability in outdoor cabinet deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | Lower PPPM (400 W), smaller SMA package (vs. DO-15), higher VC/VBR ratio (1.57) | Preferred for space-constrained PCBs where 400 W suffices; less suitable for high-energy automotive load dump | Select SMAJ7.0A only if board area is critical and surge energy remains ≤400 W; verify thermal performance with RθJA = 110 °C/W |
| 1.5KE7.5A | Same DO-15 package, identical VBR/VC specs, but commercial-grade (non-AEC-Q101), lower surge life endurance | Acceptable for non-automotive industrial or consumer use where qualification is not mandated | Choose 1.5KE7.5A for cost-sensitive non-automotive designs; avoid where AEC-Q101 validation or extended temperature operation is required |
Compared with SMAJ7.0A and 1.5KE7.5A, the P6KE7.5CHE3/73 delivers superior surge robustness (600 W), automotive qualification, and tighter thermal management via lower RθJL, making it the preferred choice for mission-critical 5 V rail protection in harsh environments.

FAQ
What is the clamping voltage of the P6KE7.5CHE3/73 under maximum surge conditions?
The P6KE7.5CHE3/73 exhibits a maximum clamping voltage (VC) of 11.3 V when subjected to its rated 53.1 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on the protected circuit during worst-case transient events. The P6KE7.5CHE3/73 maintains this clamping performance across its full operating temperature range.
Is the P6KE7.5CHE3/73 suitable for automotive applications?
Yes, the P6KE7.5CHE3/73 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay documentation. Its construction - including glass-passivated junction, DO-15 package with matte tin leads, and operation up to +175 °C junction temperature - meets requirements for engine bay, body control, and ADAS sensor protection. The HE3 suffix confirms AEC-Q101 qualification status for the P6KE7.5CHE3/73.
How does the P6KE7.5CHE3/73 differ from the P6KE7.5A-E3 variant?
The P6KE7.5CHE3/73 differs from P6KE7.5A-E3 in qualification grade: the "H" in HE3 denotes AEC-Q101 qualification, whereas E3 alone indicates commercial-grade RoHS compliance only. Both share identical electrical specifications (VBR, VC, PPPM), DO-15 package, and thermal characteristics, but the P6KE7.5CHE3/73 undergoes additional stress testing per AEC-Q101 for automotive deployment.
What is the maximum reverse leakage current of the P6KE7.5CHE3/73 at its stand-off voltage?
At its rated stand-off voltage (VWM) of 6.40 V and ambient temperature of 25 °C, the P6KE7.5CHE3/73 exhibits a maximum reverse leakage current (ID) of 500 μA. This low leakage ensures minimal power loss in standby mode and avoids false triggering in high-impedance sensing circuits. The P6KE7.5CHE3/73 maintains this specification across its full operating temperature range.
Can the P6KE7.5CHE3/73 be used in bi-directional configurations?
No, the P6KE7.5CHE3/73 is a uni-directional TVS diode, as indicated by the "A" suffix and absence of "CA" in its part number. Bi-directional variants (e.g., P6KE7.5CA) are required for AC line or differential signal protection. Using the P6KE7.5CHE3/73 in bi-directional applications would result in forward conduction during negative transients, potentially causing failure or incorrect clamping behavior.
