Product details
Overview
P6KE75 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 75 V, minimum/maximum VBR of 67.5 V / 82.5 V at 1 mA test current, stand-off voltage VWM of 60.7 V, clamping voltage VC of 108 V at 5.8 A peak surge current, and operates across -55°C to +175°C junction temperature range - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the P6KE75 datasheet, P6KE75 pinout, P6KE75 application, or P6KE75 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity with cathode band marking, 108 V clamping performance under 10/1000 µs surge, low leakage (<1 µA at 60.7 V), and AEC-Q101 qualification eligibility (via H-suffix variants).
Technical Context
The P6KE75 implements a silicon avalanche diode structure optimized for fast transient suppression in high-energy surge events. Its 10/1000 µs waveform rating delivers 600 W peak pulse power, with clamping response time <1.0 ps from 0 V to VBR, and dynamic impedance low enough to limit voltage overshoot during ESD or lightning-induced transients.
It operates as a single-die, unidirectional device with defined polarity (cathode band), rated for steady-state dissipation of 5 W at 75°C on 5×5 mm copper pads. The junction temperature range (-55°C to +175°C) and UL 94V-0 molding compound support under-hood automotive and industrial environments where thermal cycling and flammability compliance are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 67.5 V / 82.5 V at 1 mA - defines reliable avalanche initiation window for predictable clamping onset |
| VWM | 60.7 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPP | 108 V at 5.8 A - clamped voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPK | 600 W - peak pulse power handling per single 10/1000 µs transient event |
| TJ max | +175°C - enables operation in high-temperature engine bay or industrial control enclosures |
| Package | DO-204AC (DO-15) - standard axial leaded package with tin-plated leads, RoHS/halogen-free compliant |

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converters and LDOs. Use Value: Limits input rail to ≤108 V during 60 V/100 ms load dump, preventing MOSFET gate oxide rupture and regulator latch-up. |
Use Scenario: 4–20 mA current loop transmitters interfacing with PLC analog inputs in factory automation. IC Role / Device Role / Timing Role: Bidirectional or unidirectional surge shunt on loop terminals (e.g., between +IN and GND). Use Value: Clamps EFT bursts (IEC 61000-4-4) and cable discharge events to <108 V, preserving ADC accuracy and isolator integrity. |
| Lighting System Surge Suppression | ESD Protection for Automotive Infotainment |
|
Use Scenario: LED driver inputs in headlamp modules subjected to ISO 16750-2 transient tests (Pulse 1, 2a, 3a/b). IC Role / Device Role / Timing Role: First-line TVS on main DC input, coordinated with downstream ceramic capacitors. Use Value: Absorbs 600 W surges without degradation, maintaining <100 ns response to protect buck controller ICs and gate drivers. |
Use Scenario: USB, HDMI, or LVDS interfaces in infotainment head units exposed to human-body-model (HBM) ESD. IC Role / Device Role / Timing Role: Unidirectional TVS on VBUS or power rails feeding interface ICs (e.g., USB transceivers). Use Value: Sub-1 µA leakage at 60.7 V avoids quiescent current penalties; 108 V clamping prevents latch-up in 3.3 V/5 V PHYs. |
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 SMAJ75A | Same DO-214AC (SMA) package; 75 V VBR min/max = 71.3–78.8 V; VC = 121 V @ 4.9 A; lower PPK = 400 W | Higher clamping voltage reduces protection margin; better suited for space-constrained PCBs where SMA footprint is preferred | Select when board layout favors surface-mount and 121 V clamping is acceptable for downstream 15 V-rated components |
| ON Semiconductor 1.5KE75A | Same DO-201AD (DO-27) axial package; VBR = 71.3–78.8 V; VC = 121 V @ 4.9 A; PPK = 1500 W | Higher surge rating but larger DO-27 body (5.6 mm Ø vs. DO-15's 3.6 mm); not drop-in compatible due to mechanical fit | Choose for higher-energy threat environments (e.g., railway power systems) where physical size allows DO-27 mounting |
Compared with SMAJ75A and 1.5KE75A, the P6KE75 offers optimal balance of axial DO-15 form factor, 600 W capability, and 108 V clamping - making it ideal for cost-sensitive, thermally constrained automotive and industrial designs requiring proven AEC-Q101 compatibility via H-suffix variants.

FAQ
What is the maximum clamping voltage of the P6KE75 under standard surge conditions?
The P6KE75 has a maximum clamping voltage VC of 108 V at 5.8 A peak pulse current (IPP) under the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream circuitry during a full-rated 600 W transient event. The P6KE75 maintains this clamping performance across its operating temperature range.
Is the P6KE75 unidirectional or bidirectional, and how is polarity identified?
The P6KE75 is a unidirectional TVS diode, intended for DC line protection where polarity is fixed. Polarity is identified by a cathode band marked on the DO-204AC (DO-15) package body - the banded end connects to the protected line (e.g., 24 V rail), while the unbanded end connects to ground. Bidirectional variants use "CA" suffixes (e.g., P6KE75CA), which the P6KE75 does not carry.
Does the P6KE75 meet automotive qualification standards?
The base P6KE75 is not AEC-Q101 qualified; however, the P6KE75H variant (with "H" suffix) is explicitly AEC-Q101 qualified per the manufacturer's ordering information. This qualification covers temperature cycling, humidity testing, and surge endurance - making P6KE75H suitable for automotive powertrain, chassis, and body electronics applications where reliability under harsh conditions is mandatory.
What is the leakage current specification for the P6KE75 at its rated standoff voltage?
The P6KE75 exhibits a maximum reverse leakage current ID of 1 µA when biased at its rated standoff voltage VWM of 60.7 V. This low leakage ensures minimal power loss in always-on systems such as automotive body controllers or industrial sensors operating from battery or 24 V supplies, supporting long-term energy efficiency and thermal stability.
Can the P6KE75 be used in parallel to increase surge current handling?
No - the P6KE75 should not be paralleled for increased surge capacity. Due to manufacturing tolerances in VBR (67.5–82.5 V), uneven current sharing will occur during transients, causing one device to absorb most of the energy and likely fail prematurely. For higher surge ratings, select a single higher-power device (e.g., 1.5KE75A) or implement staged protection with upstream fusing and coordinated clamping.
