Product details
Overview
P6KE7.5 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 7.5 V, a stand-off voltage of 6.05 V, clamps at ≤11.7 V under 500 A surge current (10/1000 µs), and operates within -55°C to +175°C junction temperature range - deployed in automotive lighting control modules and industrial sensor interface circuits.
For engineers reviewing the P6KE7.5 datasheet, P6KE7.5 pinout, P6KE7.5 application, or P6KE7.5 equivalent, this page delivers verified electrical parameters, DO-15 package mechanical data, clamping performance at rated surge current, polarity marking convention, and AEC-Q101-qualified alternatives where applicable.
Technical Context
The P6KE7.5 is a single-die, unidirectional silicon avalanche diode optimized for fast transient suppression on low-voltage DC lines. Its 10/1000 µs surge rating of 600 W and sub-nanosecond response time (<1.0 ps from 0 V to VBR) enable effective protection against ESD, EFT, and inductive switching spikes.
It exhibits low dynamic impedance and typical reverse leakage <1 µA above 10 V, with a temperature coefficient of VBR at 0.061 %/°C. The device uses a DO-204AC (DO-15) package with cathode band polarity marking and pure tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.05 V - Maximum continuous reverse operating voltage before significant leakage begins; sets upper limit for safe DC rail operation. |
| VBR (min/max) | 6.75 V / 8.25 V - Breakdown occurs within this range at 10 mA test current; defines threshold for clamping activation. |
| VC @ IPP | 11.7 V @ 500 A - Peak clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected IC inputs. |
| PPK | 600 W - Non-repetitive peak pulse power handling capability; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IR @ VWM | <1 µA - Reverse leakage at stand-off voltage; ensures minimal power loss and signal integrity in high-impedance circuits. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial ambient environments. |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package with 0.400 g mass; compatible with legacy wave-solder and hand-solder processes. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or lowest potential node; forms current path during reverse-biased clamping event. |

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 P6KE7.5A | Narrower VBR range (7.13–7.88 V) and higher VWM (6.40 V); identical 600 W rating and DO-15 package. | Better suited for tighter tolerance designs where 6.40 V stand-off margin is required over 6.05 V. | Select P6KE7.5A when higher VWM improves noise immunity without compromising clamping performance (VC = 11.3 V @ 500 A). |
| ON Semiconductor 1.5KE7.5 | Same VBR (6.75–8.25 V) and VC (11.7 V), but lower surge rating (1500 W vs. 600 W) and larger DO-201 package. | Used in higher-energy surge environments (e.g., telecom power feeds) where board space allows larger footprint. | Choose 1.5KE7.5 only if system-level testing confirms need for >600 W dissipation and PCB layout accommodates DO-201 mounting. |
Compared with P6KE7.5, the P6KE7.5A offers tighter VBR tolerance and higher VWM for improved noise margin, while the 1.5KE7.5 provides higher surge capacity in a physically larger package - neither is pin-compatible, and both require layout verification for mechanical fit and thermal relief.

FAQ
What is the maximum clamping voltage of P6KE7.5 under surge conditions?
The P6KE7.5 clamps to a maximum of 11.7 V when subjected to a 500 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper bound of voltage seen by protected circuitry during worst-case transient events - critical for ensuring compatibility with 5 V logic ICs' absolute maximum ratings. The P6KE7.5 maintains this clamping performance across its full operating temperature range.
Is P6KE7.5 suitable for bidirectional transient protection?
No, P6KE7.5 is a unidirectional TVS diode intended for DC line protection with defined polarity (cathode band marking). For bidirectional applications such as AC lines or differential data buses, the P6KE7.5CA variant must be used - it shares the same voltage ratings but conducts in both directions. Using P6KE7.5 in reverse-biased AC configurations risks permanent failure due to forward conduction during negative half-cycles.
Does P6KE7.5 meet automotive qualification standards?
The base P6KE7.5 is not AEC-Q101 qualified; however, the P6KE7.5H variant - explicitly marked with "H" suffix in the ordering code - undergoes full AEC-Q101 stress testing including HTGB, HTRB, and temperature cycling. This makes P6KE7.5H suitable for automotive under-hood applications like body control modules and lighting drivers where reliability validation is mandatory.
What is the reverse leakage current specification for P6KE7.5 at its stand-off voltage?
At its rated stand-off voltage of 6.05 V, the P6KE7.5 exhibits a maximum reverse leakage current of 500 µA - significantly lower than many competing TVS diodes. This low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes quiescent power loss in battery-powered systems. The P6KE7.5 maintains this performance across its full -55°C to +175°C operating junction temperature range.
How does the DO-15 package of P6KE7.5 impact thermal performance in PCB layout?
The DO-15 package of P6KE7.5 relies on lead thermal conduction rather than pad-based heat sinking; its steady-state power dissipation is rated at 5 W at 75°C ambient with 9.5 mm lead lengths. To achieve optimal thermal performance, maintain ≥2 mm clearance around leads, use ≥5 × 5 mm copper pads per terminal, and avoid excessive conformal coating over the body - all validated in Taiwan Semiconductor's P2203 datasheet revision.
