Product details
Overview
P6KE7.5H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 7.5V, clamps transients to ≤11.7V at 53A peak surge current, and delivers sub-nanosecond response time (<1.0ps from 0V to VBR) - deployed in automotive body control modules, industrial sensor interfaces, and 12V supply rail protection.
For engineers reviewing the P6KE7.5H datasheet, P6KE7.5H pinout, P6KE7.5H application, or P6KE7.5H equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility with high-reliability PCB layouts, 6.05V stand-off voltage tolerance, and verified clamping performance under 10/1000μs surge waveforms.
Technical Context
The P6KE7.5H operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its minimum breakdown voltage of 6.75V (tested at 10mA). Its low dynamic impedance ensures stable clamping during fast transients, while junction temperature capability up to +175°C supports under-hood automotive deployment.
It complies with ANSI/IEEE C62.35 surge standards and exhibits <1μA reverse leakage at 6.05V (VWM), enabling low-power system compatibility. The device is not bidirectional - polarity is marked on the cathode band per DO-204AC mechanical specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W at 10/1000μs waveform - sustains single-event surges typical of ISO 7637-2 pulse 1/2a/5a in automotive systems |
| Breakdown Voltage VBR | 6.75–8.25V min/max at 10mA - defines precise conduction threshold for 7.5V nominal rail protection |
| Stand-Off Voltage VWM | 6.05V - maximum continuous reverse voltage before leakage exceeds 500μA, ensuring no false triggering on 5V–6V logic rails |
| Clamping Voltage VC | ≤11.7V at 53A IPP - limits downstream IC stress to safe levels during 10/1000μs transients |
| Junction Temperature Range | −55°C to +175°C - enables operation in engine compartment, industrial motor drives, and outdoor power electronics |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with tin-plated leads, UL 94V-0 molding compound |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical glass-passivated body with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002; weight ≈0.400g. Polarity is unidirectional - cathode band denotes the terminal connected to circuit ground or return path during clamping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input/Line side | Connected to protected line (e.g., 12V battery feed); conducts surge current toward cathode during overvoltage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ7.5A | Same DO-214AC package; 7.5V nominal, 12.5V clamping at 49.3A; AEC-Q101 qualified; slightly higher VC and lower IPP | Preferred where board space constraints favor surface-mount; less suitable for through-hole legacy automotive harnesses | Select for SMT-based new designs requiring identical electrical specs but smaller footprint |
| Vishay 1.5KE7.5C | Higher 1500W rating; DO-201AD package; bidirectional; 12.4V clamping at 121A; not AEC-Q101 qualified | Used in AC-coupled telecom or industrial AC line protection where bidirectional clamping and higher surge margin are required | Choose only for non-automotive, high-energy AC applications - not drop-in for P6KE7.5H's unidirectional AEC-Q101 use case |
Compared with SMAJ7.5A and 1.5KE7.5C, the P6KE7.5H uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and optimized 600W/11.7V clamping for cost-sensitive, high-volume automotive DC rail protection - making it irreplaceable in legacy harness-integrated modules.

FAQ
What is the clamping voltage of the P6KE7.5H at its rated peak surge current?
The P6KE7.5H clamps to a maximum of 11.7V at 53A peak pulse current (IPP), measured under the standard 10/1000μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream components remain within safe voltage limits during surge events. The P6KE7.5H achieves this with low dynamic impedance and rapid avalanche onset.
Is the P6KE7.5H unidirectional or bidirectional?
The P6KE7.5H is a unidirectional TVS diode, indicated by its single cathode band marking and specified breakdown behavior only in reverse bias. It does not conduct in forward direction beyond typical diode drop and is not rated for bidirectional surge suppression. For bidirectional protection, TSC offers the P6KE7.5CA variant - the P6KE7.5H must be oriented correctly in-circuit with cathode toward ground.
Does the P6KE7.5H meet AEC-Q101 requirements?
Yes, the P6KE7.5H is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirmed in the official TSC P2203 datasheet revision. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock - making it suitable for automotive powertrain, chassis, and body electronics applications where reliability is critical.
What is the maximum steady-state power dissipation for the P6KE7.5H?
The P6KE7.5H has a steady-state power dissipation (PD) of 5W at TA = 75°C with 9.5mm lead lengths mounted on 5×5 mm copper pads. This rating applies only to continuous DC or low-frequency conditions - the device is intended for transient suppression, not sustained power dissipation. Exceeding this limit risks thermal runaway and permanent failure of the P6KE7.5H.
How does the P6KE7.5H compare to the P6KE7.5A variant?
The P6KE7.5H and P6KE7.5A share identical electrical parameters (VBR = 7.13–7.88V, VC = 11.3V at 55A), but only the P6KE7.5H carries AEC-Q101 qualification. The "H" suffix denotes automotive-grade screening and traceability; the "A" suffix indicates tighter VBR tolerance but no automotive qualification. For production automotive systems, the P6KE7.5H is mandatory - the P6KE7.5A is limited to commercial/industrial use.
