Product details
Overview
P6KE7.5HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection on DC power rails and signal lines. It features a 7.13 V minimum breakdown voltage (VBR), 6.40 V maximum stand-off voltage (VWM), 11.3 V clamping voltage (VC) at 53.1 A peak pulse current, 600 W peak pulse power rating with 10/1000 µs waveform, and AEC-Q101 qualification for automotive-grade reliability in engine control units and body electronics.
For engineers reviewing the P6KE7.5HE3/54 datasheet, P6KE7.5HE3/54 pinout, P6KE7.5HE3/54 application, or P6KE7.5HE3/54 equivalent, this device serves as a robust, RoHS-compliant, lead-free transient suppressor for high-surge industrial power supplies, automotive sensor interfaces, and telecom line protection where fast response (<1 ns), low clamping ratio (VC/VWM ≈ 1.77), and thermal stability up to +175 °C junction temperature are critical.
Technical Context
The P6KE7.5HE3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering bi-directional surge suppression capability only when configured in dual-diode arrangements - its native configuration is uni-directional, with cathode marked by axial band. It exhibits 0.061 %/°C temperature coefficient of VBR, enabling stable breakdown across -55 °C to +175 °C operating range.
Its 20 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient rating support reliable operation under repetitive 0.01 % duty cycle pulses. The device complies with JESD 22-B106 (275 °C solder dip, 10 s) and JESD 201 Class 2 whisker testing, confirming suitability for automated assembly in harsh-environment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.40 V maximum - ensures reliable blocking of normal 5 V rail noise without leakage-induced power loss |
| VBR @ IT = 10 mA | 7.13–7.88 V - defines precise avalanche initiation threshold for predictable clamping onset |
| VC @ IPPM = 53.1 A | 11.3 V - limits downstream IC stress during 600 W transients (10/1000 µs) |
| IPPM | 53.1 A - quantifies maximum non-repetitive surge current it can safely divert |
| PPPM | 600 W - specifies peak transient energy absorption capacity per industry-standard waveform |
| TJ max. | +175 °C - enables use in under-hood automotive modules and high-temperature industrial enclosures |

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 VWM (5.8 V), same DO-214AC package, 400 W PPPM | Better suited for tighter 3.3 V rail protection; lower surge margin than P6KE7.5HE3/54 | Select SMAJ7.0A only if board space constraints require SMD mounting and 400 W rating suffices. |
| 1.5KE7.5A | Same VBR/VC specs, 1500 W PPPM, larger DO-201AD package | Used in higher-energy industrial motor drives where 600 W is insufficient | Choose 1.5KE7.5A when system-level surge tests exceed IEC 61000-4-5 Level 4 and DO-201AD footprint is acceptable. |
Compared with SMAJ7.0A and 1.5KE7.5A, the P6KE7.5HE3/54 delivers optimal balance of AEC-Q101 qualification, 600 W surge handling, DO-15 through-hole compatibility, and cost-effective protection for mid-tier automotive and industrial designs - neither underspecified nor over-engineered for typical 5 V rail applications.

FAQ
What is the maximum clamping voltage of the P6KE7.5HE3/54 under rated surge conditions?
The P6KE7.5HE3/54 has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures that protected 5 V circuits remain below absolute maximum ratings during transient events. The P6KE7.5HE3/54 achieves this with low dynamic impedance and stable avalanche characteristics across its operating temperature range.
Is the P6KE7.5HE3/54 suitable for automotive applications?
Yes, the P6KE7.5HE3/54 is AEC-Q101 qualified and carries the HE3 suffix indicating compliance with JESD 201 Class 2 whisker testing and RoHS requirements. Its -55 °C to +175 °C operating junction temperature range, glass-passivated junction, and validated surge performance make it appropriate for under-hood and cabin-mounted automotive subsystems. The P6KE7.5HE3/54 is commonly deployed in body control modules and sensor interface protection circuits.
What does the "HE3/54" suffix mean in P6KE7.5HE3/54?
The "HE3" suffix denotes AEC-Q101 qualification, RoHS compliance, and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred packaging code - 4000-piece 13-inch paper tape and reel. This packaging format supports automated pick-and-place insertion and ensures consistent lead coplanarity and solderability per J-STD-002. The P6KE7.5HE3/54 is supplied in this configuration to meet high-volume manufacturing requirements.
How does the P6KE7.5HE3/54 compare to bi-directional TVS diodes like P6KE7.5CA?
The P6KE7.5HE3/54 is uni-directional and includes a cathode band for polarity identification, whereas P6KE7.5CA is bi-directional with no marking and symmetrical clamping in both polarities. The P6KE7.5HE3/54 offers lower leakage and tighter VBR tolerance for DC rail protection, while P6KE7.5CA suits AC-coupled or floating signal lines. Selection depends on circuit topology - the P6KE7.5HE3/54 is preferred for grounded 5 V supplies where unidirectional clamping suffices.
What is the thermal resistance of the P6KE7.5HE3/54, and how does it affect layout design?
The P6KE7.5HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. In PCB layout, this means copper pour area under the cathode/anode leads significantly improves heat dissipation during repetitive surges. For continuous operation near 5.0 W power dissipation, the P6KE7.5HE3/54 requires ≥25 mm² of 2-oz copper connected to each lead - verified in Vishay's Fig. 5 derating curve.
