Product details
Overview
P6KE10-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 9.5 V minimum breakdown voltage (VBR), 8.55 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, 600 W peak pulse power rating with 10/1000 µs waveform, and operates across -55 °C to +175 °C junction temperature range - deployed in automotive body control modules to safeguard microcontroller I/O against load-dump transients.
For engineers reviewing the P6KE10-E3/73 datasheet, P6KE10-E3/73 pinout, P6KE10-E3/73 application, or P6KE10-E3/73 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, standoff voltage compatibility with nominal rail voltage (e.g., 9 V systems), thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and DO-204AC (DO-15) through-hole package mechanical fit.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 8.55 V), but triggers into low-impedance conduction when transient voltage exceeds its 9.5–10.5 V breakdown range, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance and repeatable clamping behavior across temperature.
Designed for single-pulse and low-duty-cycle repetitive transients (0.01 % max duty cycle), it handles 41.4 A peak pulse current per 10/1000 µs waveform while maintaining ≤14.5 V clamping - critical for protecting 12 V automotive electronics where ISO 7637-2 Pulse 1 and Pulse 2a surges demand sub-16 V clamping to avoid latch-up in 5 V logic interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM Standoff Voltage | 8.55 V - maximum continuous reverse operating voltage before significant leakage; sets upper limit for compatible 9 V nominal rails |
| VBR Breakdown Voltage | 9.50–10.5 V at 1 mA - precise triggering threshold ensuring reliable activation before protected IC's 12 V abs max rating |
| VC Clamping Voltage | 14.5 V at 41.4 A - maximum voltage seen by protected circuit during worst-case surge; enables safe margin below 16 V system limits |
| PPPM Peak Pulse Power | 600 W - energy-handling capacity for 10/1000 µs transients; sufficient for ISO 7637-2 Pulse 1 (−100 V, 0.5 Ω, 50 ms) |
| RθJL Thermal Resistance | 20 °C/W - junction-to-lead thermal path enables sustained 5.0 W power dissipation at 75 °C lead temperature without derating |
| TJ Max Operating Temp | +175 °C - supports under-hood automotive placement where ambient exceeds 125 °C |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTOL, temperature cycling, and ESD per AEC specification |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward conduction terminal | Connected to ground or lower-potential node in unidirectional configuration; carries full surge current during clamping |
| Cathode (banded end) | Reverse-biased terminal | Connected to protected line (e.g., 9 V rail); color band identifies polarity for correct PCB orientation and functional protection direction |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %) and long-term parameter consistency across thermal cycling and humidity exposure |
| 600 W peak pulse power (10/1000 µs) | Provides robust protection against automotive load dump (ISO 7637-2 Pulse 5a) and inductive switching spikes without degradation |
| Fast response time (<1 ns) | Clamps transients before sensitive ICs experience overvoltage stress - critical for protecting high-speed CAN or LIN transceivers |
| AEC-Q101 qualification | Validates reliability for automotive applications including engine control units, lighting modules, and body electronics |
| Low incremental surge resistance | Minimizes VC overshoot during high di/dt events, improving clamping predictability in fast-rising transients like ESD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | DO-214AA (SMB) surface-mount package; same 10 V VWM, 14.5 V VC, but 600 W rating at 10/1000 µs; slightly higher VBR min (9.4 V) | Requires PCB re-layout for SMT assembly; better suited for space-constrained designs with automated manufacturing | Select SMBJ10A when migrating to SMT platforms or needing tighter VBR distribution (±3.5 % vs. ±5 %) |
| 1.5KE10A | Higher 1500 W peak power rating; same DO-204AC package; VWM = 8.55 V, VC = 14.5 V, but larger physical size and 1.5× higher unit cost | Used where legacy 1.5 kW surge standards apply (e.g., MIL-STD-1275B); over-spec'd for most automotive 600 W requirements | Choose 1.5KE10A only if system-level surge test requires >600 W margin or existing board footprint accommodates larger body |
Compared with SMBJ10A and 1.5KE10A, P6KE10-E3/73 delivers optimal cost-performance balance for through-hole automotive and industrial applications - matching clamping performance of both alternatives while offering AEC-Q101 qualification not found in 1.5KE10A and lower assembly cost than SMBJ10A in mixed-technology boards.

FAQ
What is the maximum clamping voltage of the P6KE10-E3/73 under surge conditions?
The P6KE10-E3/73 has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the highest voltage the protected circuit will experience during a specified transient event. The P6KE10-E3/73 maintains this clamping performance due to its low incremental surge resistance and stable glass-passivated junction.
Is the P6KE10-E3/73 suitable for automotive applications?
Yes, the P6KE10-E3/73 is AEC-Q101 qualified and rated for operation from -55 °C to +175 °C, making it suitable for under-hood and body electronics applications. Its 600 W surge capability, 14.5 V clamping voltage, and DO-204AC package with matte tin leads meet automotive requirements for load dump (ISO 7637-2 Pulse 5a), inductive switching, and ESD protection. The P6KE10-E3/73 is commonly used in body control modules and lighting control units.
How does the P6KE10-E3/73 differ from bi-directional TVS diodes like P6KE10CA?
The P6KE10-E3/73 is unidirectional and features a cathode band for polarity-sensitive placement - it blocks forward current above ~3.5 V and clamps reverse transients above ~10 V. In contrast, P6KE10CA is bi-directional with symmetrical clamping in both directions and no polarity marking. The P6KE10-E3/73 is intended for DC rail protection where polarity is fixed; P6KE10CA suits AC lines or bidirectional data paths like RS-485.
What is the standoff voltage rating of the P6KE10-E3/73, and why does it matter?
The P6KE10-E3/73 has a maximum working standoff voltage (VWM) of 8.55 V, meaning it remains non-conductive up to this DC or RMS voltage level. This rating ensures minimal leakage (<10 µA) during normal operation while allowing sufficient margin below the 9.5 V minimum breakdown voltage. Selecting a P6KE10-E3/73 for a 9 V system provides reliable protection without false triggering - a key design requirement the P6KE10-E3/73 fulfills consistently.
Can the P6KE10-E3/73 be used in place of the older P6KE10A part?
Yes, the P6KE10-E3/73 is a RoHS-compliant, commercial-grade variant of the P6KE10A with identical electrical specifications, DO-204AC packaging, and thermal characteristics. The "E3/73" suffix indicates tape-and-reel packaging (73 = 7-inch reel) and JESD201 Class 1A whisker resistance - enhancements that do not affect circuit functionality. Designers may substitute P6KE10-E3/73 for P6KE10A without layout or performance changes, and the P6KE10-E3/73 maintains full backward compatibility.
