Product details
Overview
1N6282A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection on DC power rails and signal lines. It features a 30 V breakdown voltage (VBR = 28.5–31.5 V at 1.0 mA), 25.6 V maximum working peak reverse voltage (VWM), 41.4 V clamping voltage (VC) at 36.2 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), 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 1N6282A-E3/73 datasheet, 1N6282A-E3/73 pinout, 1N6282A-E3/73 application, or 1N6282A-E3/73 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal resistance data (RθJA = 75 °C/W), and direct alternative part comparisons - all confirmed from Vishay's official 88301 document revision 09-Aug-2022.
Technical Context
This unidirectional TVS diode employs a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping action begins at VBR = 28.5–31.5 V and limits voltage to ≤41.4 V under 36.2 A (10/1000 µs), enabling robust protection of downstream MOSFETs and ICs against ESD, lightning-induced surges, and inductive switching transients.
The device is housed in a molded epoxy Case Style 1.5KE package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It supports 200 A non-repetitive forward surge current (IFSM), exhibits 3.5 V max forward voltage at 100 A, and is rated for 6.5 W steady-state power dissipation on an infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at 1.0 mA - defines precise voltage threshold where avalanche conduction initiates reliably |
| VWM | 25.6 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 41.4 V at 36.2 A (10/1000 µs) - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 1500 W - peak transient power handling capability under standardized 10/1000 µs waveform |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance determines derating needed for ambient >25 °C |
| TJ range | –55 °C to +175 °C - enables use in under-hood automotive and high-temp industrial environments |
| IFSM | 200 A (8.3 ms half-sine) - withstands high-energy inrush or fault currents without failure |

IC Role / Device Role / Timing Role: Primary shunt protector placed between power rail and ground; clamps transients before they reach LDOs and microcontrollers. Use Value: Limits rail voltage to ≤41.4 V during 36.2 A surge, preventing latch-up or gate oxide rupture in downstream 3.3 V/5 V logic. |
Use Scenario: 4–20 mA current loop transmitter interfacing with PLC analog input, subject to field wiring ESD and induced surges. IC Role / Device Role / Timing Role: Bidirectional-capable variant not used here; unidirectional 1N6282A-E3/73 protects signal return path against negative transients. Use Value: Withstands ±30 kV contact ESD (IEC 61000-4-2) while maintaining <1 µA leakage at 25.6 V, preserving loop accuracy. |
| DC Motor Drive Power Stage Protection | Telecom Line Interface Surge Suppression |
Use Scenario: H-bridge driver IC powered from 24 V bus, subjected to back-EMF spikes during PWM commutation. IC Role / Device Role / Timing Role: Mounted across motor supply rail and ground; conducts only during transient overvoltage, remaining inert during normal operation. Use Value: Clamps 1500 W surges within 1 ns, limiting voltage overshoot to 41.4 V and protecting MOSFET drain-source junctions rated for 60 V. |
Use Scenario: DSL or Ethernet PHY interface board connected to outside plant wiring vulnerable to lightning-induced surges (IEC 61000-4-5, 10/700 µs). IC Role / Device Role / Timing Role: First-stage protector upstream of choke and secondary TVS; absorbs bulk energy before it reaches sensitive transceivers. Use Value: Delivers 1500 W pulse power handling with 75 °C/W thermal resistance, enabling reliable operation without forced cooling in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Same VWM (25.6 V) and VC (48.4 V), but lower PPPM = 600 W; SMC package (smaller footprint, higher RθJA = 110 °C/W) | Preferred for space-constrained PCBs where 600 W surge immunity suffices; less suitable for repeated load-dump events | Select SMBJ30A only if layout area is limited and peak surge energy remains below 600 W - verify thermal margin at max ambient. |
| 1.5KE30A-E3/73 | Identical electrical specs and package; same Vishay 1.5KE family, identical VBR, VWM, VC, PPPM, and thermal characteristics | No functional difference; dual manufacturer marking reflects legacy part numbering (1N6282A = 1.5KE30A) | 1.5KE30A-E3/73 is a direct form-fit-function replacement; interchangeability confirmed in Vishay Doc. #88301 Table 1. |
Compared with 1N6282A-E3/73, SMBJ30A offers smaller size but reduced surge capacity and worse thermal performance, while 1.5KE30A-E3/73 is electrically and mechanically identical - making it a seamless second-source option without design or layout changes.

FAQ
What is the breakdown voltage tolerance for 1N6282A-E3/73?
The 1N6282A-E3/73 has a specified breakdown voltage range of 28.5 V to 31.5 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 30 V rating. This tight tolerance ensures predictable clamping onset across production lots and supports reliable system-level surge margin analysis in designs using the 1N6282A-E3/73.
Is 1N6282A-E3/73 RoHS compliant and lead-free?
Yes, the "E3" suffix in 1N6282A-E3/73 explicitly denotes RoHS compliance and commercial-grade qualification per Vishay documentation. The device uses matte tin-plated leads, meets JESD 201 Class 1A whisker testing, and contains no restricted substances above EU RoHS thresholds - fully documented in Vishay's 88301 datasheet revision 09-Aug-2022.
Can 1N6282A-E3/73 be used in bidirectional configurations?
No, 1N6282A-E3/73 is a unidirectional TVS diode. Its cathode band marks polarity, and it conducts only in reverse breakdown - not in forward conduction under surge. For bidirectional protection, Vishay specifies part numbers with "CA" suffix (e.g., 1.5KE30CA); the 1N6282A-E3/73 is not rated or characterized for symmetrical clamping.
What is the maximum clamping voltage of 1N6282A-E3/73 under surge conditions?
The maximum clamping voltage (VC) of 1N6282A-E3/73 is 41.4 V at 36.2 A peak pulse current with a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet and represents the highest voltage the protected circuit will experience during a standardized surge event - critical for validating compatibility with downstream IC absolute maximum ratings.
Does 1N6282A-E3/73 meet AEC-Q101 qualification?
The base 1N6282A-E3/73 is commercial-grade and not AEC-Q101 qualified. However, Vishay offers the AEC-Q101-qualified version as 1N6282AHE3_B (or 1.5KE30AHE3_B), which shares identical electrical specs but adds stress-test validation for automotive under-hood applications - confirmed in Note (2) of Vishay Doc. #88301.
