Product details
Overview
P6KE7.5CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 7.5V, clamping voltage of 11.7V at 53A peak surge current, and stand-off voltage of 6.05V - designed to protect automotive-grade power rails and signal lines against ESD, lightning-induced surges, and inductive switching transients.
For engineers reviewing the P6KE7.5CH datasheet, P6KE7.5CH pinout, P6KE7.5CH application, or P6KE7.5CH equivalent, this AEC-Q101-qualified DO-15 TVS offers verified clamping performance, low dynamic impedance, sub-nanosecond response time, and UL recognition for high-reliability board-level surge protection in automotive body electronics, lighting modules, and sensor interfaces.
Technical Context
The P6KE7.5CH operates as a unidirectional avalanche diode with a single-die DO-204AC (DO-15) package, optimized for fast transient suppression using silicon junction avalanche breakdown. Its 10/1000μs waveform rating delivers 600W non-repetitive peak pulse power, with clamping voltage tightly controlled at 11.7V under 53A surge current.
It features a maximum reverse leakage current of 500μA at 6.05V (VWM), temperature coefficient of VBR at 0.061%/°C, and junction operating range from –55°C to +175°C - enabling robust operation in under-hood automotive environments where thermal derating and long-term reliability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.05 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below breakdown |
| VBR (min/max) | 6.75 V / 8.25 V at 10 mA - Confirmed breakdown threshold range; ensures predictable turn-on during transients |
| VC @ IPP | 11.7 V at 53 A - Clamping voltage limits downstream IC stress during 10/1000μs surge events |
| PPK | 600 W - Peak pulse power handling per 10/1000μs waveform; supports IEC 61000-4-5 Level 4 immunity |
| IR @ VWM | <500 μA - Low leakage preserves system standby current in battery-powered automotive modules |
| TJ max | +175 °C - Enables placement near heat sources (e.g., motor drivers, LED drivers) without thermal shutdown |

Applications
| Automotive Lighting Systems | Body Control Modules (BCM) |
|---|---|
Use Scenario: Protecting LED driver outputs and headlamp control circuits from load dump and inductive kickback. IC Role / Device Role: Unidirectional TVS placed between 12V supply rail and ground, shunting surge energy away from driver ICs.

| Engine Management Sensors | Power Supply Input Protection |
Use Scenario: Shielding crankshaft/camshaft position sensor signal lines from alternator ripple and ignition coil coupling. IC Role / Device Role: Low-leakage TVS (IR <500μA at 6.05V) placed across differential sensor inputs to suppress common-mode transients.

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 (SMB), 7.0V nominal, 600W, bidirectional; higher VC = 12.0V @ 43.3A | Surface-mount only; lacks AEC-Q101 qualification in standard grade; lower surge current rating | Select when PCB space constraints require SMD and AEC-Q101 is not mandatory |
| 1.5KE7.5C | DO-201AD package, 7.5V nominal, 1500W rating, unidirectional; VC = 12.9V @ 116.3A; larger footprint | Higher power handling but slower thermal response; not AEC-Q101 qualified | Select when legacy through-hole design requires higher surge margin and automotive qualification is secondary |
Compared with SMBJ7.0A and 1.5KE7.5C, the P6KE7.5CH provides AEC-Q101 validation, precise 6.05V standoff for 12V systems, and DO-15 compatibility with existing automotive through-hole layouts - making it optimal for new and replacement designs requiring certified reliability.

FAQ
What is the clamping voltage of the P6KE7.5CH under maximum surge conditions?
The P6KE7.5CH has a maximum clamping voltage (VC) of 11.7 V at 53 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuitry sees no more than 11.7 V during surge events - critical for safeguarding 12 V-rated ICs and interfaces. The P6KE7.5CH maintains this clamping performance across its full operating temperature range.
Is the P6KE7.5CH suitable for automotive applications?
Yes, the P6KE7.5CH is explicitly AEC-Q101 qualified (indicated by the "H" suffix), having passed stress tests for temperature cycling, humidity bias, mechanical shock, and high-temperature reverse bias required for automotive under-hood and cabin electronics. Its –55°C to +175°C junction temperature range, UL recognition (E326243), and halogen-free construction align with automotive OEM specifications - confirming the P6KE7.5CH for use in lighting, BCM, and sensor modules.
What does the "CH" suffix mean in P6KE7.5CH?
The "CH" suffix in P6KE7.5CH denotes two key attributes: "C" indicates unidirectional configuration, and "H" confirms AEC-Q101 qualification. This distinguishes it from non-automotive variants like P6KE7.5 (no qualification) or P6KE7.5A (tighter VBR tolerance but no AEC-Q101). The P6KE7.5CH is therefore the only version in the 7.5 V family certified for automotive deployment per JESD22 and AEC standards.
How does the P6KE7.5CH compare to bidirectional TVS diodes in surge protection?
The P6KE7.5CH is unidirectional and intended for DC power rail or single-polarity signal line protection (e.g., 12 V supply to ground), offering lower leakage (<500 μA at 6.05 V) and tighter VBR tolerance than equivalent bidirectional parts. Unlike bidirectional TVS diodes such as P6KE7.5CA, the P6KE7.5CH avoids reverse conduction during normal operation - preserving efficiency in always-on automotive subsystems where quiescent current matters.
What packaging options are available for the P6KE7.5CH?
The P6KE7.5CH is supplied in DO-204AC (DO-15) package with pure tin-plated leads, compliant with J-STD-002 solderability standards. It is available in 3,500-piece tape-and-reel format (P6KE7.5CH) and 1,500-piece ammo box format (P6KE7.5CHA0G). Both options maintain full AEC-Q101 qualification and traceable lot control - ensuring consistent P6KE7.5CH performance across manufacturing batches and reflow profiles.
