Product details
Overview
1N6269A-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 8.2 V breakdown voltage (VBR = 7.79–8.61 V at 10 mA), 7.02 V maximum standoff voltage (VWM), 12.1 V clamping voltage (VC) at 200 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1N6269A-E3/73 datasheet, 1N6269A-E3/73 pinout, 1N6269A-E3/73 application, or 1N6269A-E3/73 equivalent, this part serves as a RoHS-compliant, commercial-grade, axial-lead TVS diode with glass-passivated junction, fast sub-nanosecond response, and AEC-Q101-qualified variants available under HE3 suffix - critical for automotive ECU input protection, industrial I/O conditioning, and telecom line interface hardening.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown when reverse voltage exceeds its VBR threshold, clamping transient energy within nanoseconds. Its low incremental surge resistance and 12.1 V clamping at 200 A ensure minimal overvoltage exposure to downstream circuitry during 10/1000 µs surges.
The device uses a molded epoxy case (Case Style 1.5KE) with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102, rated for 175 °C max junction temperature and 200 A non-repetitive forward surge (8.3 ms half-sine). Thermal resistance is 15.4 °C/W (junction-to-lead), enabling effective heat dissipation in leaded PCB layouts without heatsinking.

Use Scenario: Safeguarding Ethernet PHY power pins (e.g., +3.3 V bias) in outdoor network switches subjected to lightning-induced surges. IC Role / Device Role / Timing Role: TVS installed at PHY VDD pin to absorb coupled energy from nearby AC mains or antenna lines. Use Value: 1500 W rating handles multi-kV induced transients; 12.1 V clamping preserves PHY integrity without requiring additional series impedance. |
Use Scenario: Preventing output overvoltage damage in wall-mounted AC/DC adapters due to feedback loop failure or Zener degradation. IC Role / Device Role / Timing Role: TVS placed across secondary-side output capacitor to clamp fault conditions before reaching USB or charging circuitry. Use Value: 8.2 V VBR aligns with 5 V output tolerance; 200 A IFSM withstands sustained short-circuit energy until fuse opens. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA (SMB) surface-mount package; 8.0 V VBR min (7.6–8.4 V), 12.7 V VC @ 134 A, 600 W PPPM | Lower power rating and SMT footprint - suited for space-constrained consumer PCBs, not high-energy industrial rails | Select SMBJ8.0A only when board area is limited and surge energy does not exceed 600 W; verify thermal pad layout for 134 A clamping. |
| 1.5KE8.2A-E3/54 | Same die, identical electrical specs, but supplied in 13" paper tape/reel (1400 pcs) with -E3/54 suffix; same DO-201AD package and RoHS compliance | No functional difference - differs only in packaging format and reel quantity; fully interchangeable in schematic and layout | Choose 1.5KE8.2A-E3/54 for automated pick-and-place production; 1N6269A-E3/73 is optimized for manual or low-volume prototyping with 750-piece bulk packaging. |

FAQ
What is the breakdown voltage range of the 1N6269A-E3/73?
The 1N6269A-E3/73 has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at a test current of 10 mA, measured per JEDEC standards. This tight tolerance ensures consistent clamping behavior across production lots and enables precise coordination with downstream overvoltage thresholds in protected circuits. The 1N6269A-E3/73 achieves this specification using a glass-passivated silicon junction optimized for stability under thermal and electrical stress.
Is the 1N6269A-E3/73 suitable for automotive applications?
The 1N6269A-E3/73 is a commercial-grade TVS diode; however, its AEC-Q101-qualified counterpart - 1N6269AHE3_B - is explicitly certified for automotive use. While the 1N6269A-E3/73 shares identical electrical parameters and construction, it lacks formal AEC-Q101 validation. For production automotive ECUs, specify the HE3-suffixed variant; the 1N6269A-E3/73 remains appropriate for lab validation, industrial controls, and non-safety-critical vehicle subsystems where full qualification is not mandated.
What is the clamping voltage of the 1N6269A-E3/73 at its rated peak pulse current?
The 1N6269A-E3/73 clamps to a maximum of 12.1 V when subjected to its rated peak pulse current of 200 A under the standardized 10/1000 µs waveform. This value reflects worst-case incremental clamping (VC = VBR + ΔV) and is critical for determining whether downstream components - such as 5 V or 12 V regulators - remain within safe operating voltage margins during surge events. The 1N6269A-E3/73 achieves this low clamping ratio through low dynamic impedance design.
Does the 1N6269A-E3/73 have bidirectional capability?
No, the 1N6269A-E3/73 is strictly a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants in the same family carry the "CA" suffix (e.g., 1N6269CA). Using the 1N6269A-E3/73 in AC-coupled or floating signal paths would result in forward conduction during negative half-cycles, potentially causing malfunction or damage. For bidirectional protection, select the CA-series part or pair two unidirectional devices in series opposition.
What package type and lead finish does the 1N6269A-E3/73 use?
The 1N6269A-E3/73 uses the DO-201AD axial-leaded package (Case Style 1.5KE), with 0.375" (9.5 mm) lead length and UL 94 V-0 compliant epoxy molding. Its leads are matte tin-plated and qualified to J-STD-002 for solderability and JESD 201 Class 1A for whisker resistance. This finish ensures reliable reflow and hand-solder joints in commercial and industrial manufacturing, and the axial form factor supports high-current chassis grounding and through-hole mechanical retention.
