Product details
Overview
1N6269A-E3/51 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 7.79 V to 8.61 V breakdown voltage (VBR) at 10 mA, 7.02 V standoff voltage (VWM), 12.1 V clamping voltage (VC) at 124 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1N6269A-E3/51 datasheet, 1N6269A-E3/51 pinout, 1N6269A-E3/51 application, or 1N6269A-E3/51 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under surge conditions, and direct alternatives for ESD/lightning transient suppression in 24 V control systems.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its clamping action activates within 1 ns when exposed to transients exceeding 7.02 V, limiting downstream voltage to ≤12.1 V at 124 A.
The device operates across -55 °C to +175 °C junction temperature range and supports 200 A non-repetitive forward surge current (IFSM). Thermal resistance is 15.4 °C/W (junction-to-lead), enabling reliable operation without heatsinking in moderate-duty-cycle applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - defines precise voltage threshold for avalanche conduction onset |
| VWM | 7.02 V - maximum continuous reverse working voltage before leakage exceeds 200 µA |
| VC @ IPPM | 12.1 V at 124 A - clamped voltage during 10/1000 µs surge, limiting stress on protected ICs |
| PPPM | 1500 W - peak pulse power handling capability per single 1 ms transient event |
| IPPM | 124 A - maximum non-repetitive peak pulse current supported with defined waveform |
| TJ max. | +175 °C - enables use in under-hood automotive and high-temperature industrial environments |
| RθJL | 15.4 °C/W - low thermal resistance allows efficient heat transfer to PCB leads without external heatsink |

Applications
| Automotive Sensor Interface | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and Hall-effect sensors from load dump and ISO 7637-2 pulses in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between signal line and chassis ground to divert surge energy away from IC pins. Use Value: Limits transient voltage to ≤12.1 V during 124 A events, preserving signal integrity and preventing latch-up in 5 V tolerant receivers. |
Use Scenario: Safeguarding 24 V DC digital input modules against field-wiring induced transients in factory automation cabinets. IC Role / Device Role / Timing Role: Front-end protection element mounted directly at terminal block to absorb inductive kickback from solenoid coils. Use Value: Clamps 10/1000 µs surges to 12.1 V while sustaining 200 A single-pulse forward surge, eliminating need for additional series impedance. |
| Telecom Power Supply Rail | Consumer Appliance Motor Control |
Use Scenario: Secondary-side overvoltage suppression on 48 V telecom rectifier outputs exposed to lightning-induced surges on AC mains feeders. IC Role / Device Role / Timing Role: Standoff-rated TVS placed across output capacitor to clamp sustained overvoltage beyond 7.02 V. Use Value: Maintains system uptime by preventing MOSFET gate oxide failure during 1500 W transient events without derating at +85 °C ambient. |
Use Scenario: Protecting microcontroller GPIOs and H-bridge drivers from back-EMF spikes generated by brushed DC motors in smart home appliances. IC Role / Device Role / Timing Role: Localized clamp at motor driver IC supply pin to suppress fast-rising (<10 ns) inductive spikes. Use Value: Sub-1 ns response prevents false triggering of internal protection circuits and eliminates need for RC snubbers in cost-sensitive designs. |
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, 7.0 V VWM, 11.2 V VC @ 102 A, 600 W PPPM | Lower power rating; suited for space-constrained PCBs where 1500 W headroom is unnecessary | Select SMBJ7.0A for compact layouts requiring surface-mount assembly and moderate surge immunity (IEC 61000-4-5 Level 2). |
| 1.5KE8.2A | Same 1.5KE package, identical VBR/VWM/VC specs, but standard bulk packaging (no E3/51 tape-and-reel) | No RoHS-compliant lead finish or JESD 201 whisker qualification; not suitable for automotive or high-reliability production | Choose 1.5KE8.2A only for prototyping or non-RoHS legacy systems where traceability and solderability certification are not required. |
Compared with SMBJ7.0A, the 1N6269A-E3/51 delivers 2.5× higher pulse power and axial-leaded mechanical robustness for through-hole mounting; versus 1.5KE8.2A, it adds RoHS compliance, JESD 201 Class 1A whisker resistance, and tape-and-reel delivery for automated SMT line compatibility.

FAQ
What is the breakdown voltage range of the 1N6269A-E3/51?
The 1N6269A-E3/51 has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V measured at 10 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable design margining in 5 V–12 V systems where overvoltage thresholds must be precisely controlled.
Does the 1N6269A-E3/51 meet automotive qualification standards?
The 1N6269A-E3/51 itself is RoHS-compliant and commercial-grade; however, its AEC-Q101 qualified variant is designated as 1N6269AHE3_B. That version undergoes full stress testing per AEC-Q101 including HTGB, HTRB, and temperature cycling - making it suitable for engine control units and ADAS sensor modules where automotive-grade reliability is mandatory.
What is the maximum clamping voltage of the 1N6269A-E3/51 during a surge event?
The 1N6269A-E3/51 clamps to a maximum of 12.1 V when subjected to its rated 124 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the worst-case voltage seen by downstream circuitry during full-power transient events.
Can the 1N6269A-E3/51 be used in bidirectional configurations?
No - the 1N6269A-E3/51 is strictly unidirectional. Bidirectional variants in the same family carry the "CA" suffix (e.g., 1N6269CA). Using the 1N6269A-E3/51 in AC-coupled or symmetrical signal paths would result in forward conduction during negative half-cycles and potential failure.
What package type does the 1N6269A-E3/51 use, and what are its key mechanical properties?
The 1N6269A-E3/51 uses the JEDEC DO-201AD (Case Style 1.5KE) axial package: molded epoxy body meeting UL 94 V-0, matte tin-plated leads solderable per J-STD-002, and cathode identified by a color band. Lead length is 0.375" (9.5 mm), and thermal resistance junction-to-lead is 15.4 °C/W.
