Product details
Overview
P6KE75CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 71.3 V minimum breakdown voltage (VBR), 64.1 V maximum standoff voltage (VWM), 103 V clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power dissipation with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE75CAHE3/54 datasheet, P6KE75CAHE3/54 pinout, P6KE75CAHE3/54 application, or P6KE75CAHE3/54 equivalent, this device is evaluated for bidirectional surge suppression in AEC-Q101-qualified systems where clamping voltage margin, thermal derating above 25 °C, and DO-15 package compatibility with legacy PCB footprints are critical selection criteria.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), low incremental surge resistance, and fast response time (<1 ns) to ESD and lightning-induced transients.
The device is rated for 175 °C maximum junction temperature and exhibits a +0.105 %/°C temperature coefficient of VBR, supporting reliable operation across extended automotive and industrial ambient ranges. Thermal resistance from junction to lead is 20 °C/W, allowing direct solder-mount thermal coupling to PCB copper for enhanced power handling during repetitive surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V maximum - defines highest continuous DC or RMS voltage the device blocks without leakage exceeding 1.0 μA |
| VBR (min/max) | 71.3 V / 78.8 V at 1.0 mA - ensures predictable turn-on threshold under transient stress with tight 5% tolerance |
| VC @ IPPM | 103 V at 5.8 A - limits downstream component voltage exposure during 10/1000 μs surge events |
| PPPM | 600 W - supports single-event surge immunity per IEC 61000-4-5 Level 4 (4 kV) when properly routed |
| IPPM | 5.8 A - peak current capability derived from 10/1000 μs waveform; de-rates linearly above 25 °C ambient |
| TJ max. | 175 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures |
| Package | DO-15 (DO-204AC) - industry-standard axial-leaded package with 0.242–0.258 inch body length, compatible with wave-solder and hand-solder processes |
Pinout & Package
DO-15 (DO-204AC) package: axial-leaded, molded epoxy case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; conducts equally in either direction once VBR exceeded |
| Lead 1 | PCB connection point | Direct thermal path to copper pour; RθJL = 20 °C/W enables effective heat extraction during surge |
| Lead 2 | PCB connection point | Electrically identical to Lead 1; no functional distinction - used for mechanical mounting and current return |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | DO-214AA package; 75 V nominal VBR; 600 W rating; lower RθJA (50 °C/W vs. 75 °C/W) | Better suited for surface-mount layouts with limited board space; requires rework of footprint and stencil | Select SMBJ75CA when SMT assembly is mandatory and thermal performance under sustained surges is prioritized. |
| 1.5KE75CA | Higher 1500 W PPPM; same DO-15 package; VBR 71.3–78.8 V; larger body (1.25" length) | Used where higher single-pulse energy absorption is required, e.g., mains-connected equipment with high source impedance | Choose 1.5KE75CA only if system-level testing confirms need for >600 W surge capacity; otherwise P6KE75CAHE3/54 offers optimal cost/performance balance. |
Compared with SMBJ75CA and 1.5KE75CA, P6KE75CAHE3/54 delivers AEC-Q101 qualification in the compact DO-15 form factor with verified 600 W surge capability - making it the preferred choice for cost-sensitive, high-reliability automotive and industrial designs where axial-leaded mounting is acceptable and thermal management via PCB copper is feasible.

FAQ
What is the clamping voltage of P6KE75CAHE3/54 at its rated peak pulse current?
The P6KE75CAHE3/54 has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE75CAHE3/54 maintains this clamping performance across its full operating temperature range when derated per Figure 2 in the Vishay datasheet 88369.
Is P6KE75CAHE3/54 suitable for automotive applications?
Yes, P6KE75CAHE3/54 is AEC-Q101 qualified and specifically rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its DO-15 package, 175 °C maximum junction temperature, and stable VBR temperature coefficient (+0.105 %/°C) meet stringent automotive environmental and reliability requirements. The HE3 suffix explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature.
How does the bidirectional design of P6KE75CAHE3/54 affect its circuit implementation?
The bidirectional design of P6KE75CAHE3/54 means it functions identically in both polarities - there is no anode or cathode marking, and it clamps symmetrically above ±71.3 V. This allows direct placement across AC-coupled lines, transformer secondaries, or floating differential pairs without concern for orientation. Unlike unidirectional TVS diodes, P6KE75CAHE3/54 eliminates risk of reverse-bias misapplication in dual-rail or AC signal protection schemes.
What is the standoff voltage rating for P6KE75CAHE3/54, and why is it important?
The maximum standoff voltage (VWM) for P6KE75CAHE3/54 is 64.1 V - the highest continuous DC or RMS voltage the device blocks while maintaining reverse leakage below 1.0 μA. This rating ensures the P6KE75CAHE3/54 remains non-conductive during normal operation in 48 V or 60 V systems, preventing power loss or false triggering. Selecting a VWM ≥10–15% above the system's maximum operating voltage is critical to avoid premature conduction.
Does P6KE75CAHE3/54 require heatsinking for standard surge conditions?
No additional heatsink is required for single-event surge conditions, as the P6KE75CAHE3/54 dissipates energy transiently. However, for repetitive surges or elevated ambient temperatures, thermal performance relies on PCB copper area connected to its leads: the device's RθJL is 20 °C/W, so 1–2 cm² of 2 oz copper per lead significantly improves power handling. The P6KE75CAHE3/54 is not intended for continuous power dissipation - its 5.0 W steady-state rating applies only with infinite heatsink at TL = 75 °C.
