Product details
Overview
1N6282AHE3_B/C 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 30 V breakdown voltage (VBR = 28.5–31.5 V at 1.0 mA), 25.6 V maximum standoff voltage (VWM), 41.4 V clamping voltage at 36.2 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 1N6282AHE3_B/C datasheet, 1N6282AHE3_B/C pinout, 1N6282AHE3_B/C application, or 1N6282AHE3_B/C equivalent, this part delivers verified AEC-Q101 qualification (HE3 suffix), RoHS-compliant matte tin-plated leads, UL 94 V-0 molded epoxy package, and validated clamping performance for automotive body electronics, industrial PLC I/O protection, and telecom line interface circuits.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (25.6 V), it avalanches into low-impedance conduction to divert surge current away from downstream components. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling sub-nanosecond response time (<1 ns) and repeatable clamping under repetitive 0.01% duty cycle pulses.
The device is rated for 175 °C maximum junction temperature, supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits 3.5 V max forward voltage at 100 A - critical for minimizing power loss during high-current clamping events in 24 V and 36 V automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at 1.0 mA - defines precise avalanche initiation threshold for reliable overvoltage detection |
| VWM | 25.6 V - maximum continuous reverse operating voltage before leakage rises above 1.0 µA |
| VC @ IPPM | 41.4 V at 36.2 A - clamping voltage during 1500 W transient, limiting stress on protected ICs |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity for lightning and load-dump events |
| IFSM | 200 A (8.3 ms half-sine) - surge current capability without bond-wire fusing in automotive cranking scenarios |
| TJ max. | 175 °C - enables operation in under-hood environments and high-power industrial enclosures |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 compliant |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | DO-214AA package (SMB), 30 V VBR, 48.4 V VC @ 31.3 A, 600 W PPPM | Lower power rating and surface-mount only; unsuitable for high-energy 1500 W surges | Select only for space-constrained PCBs where 600 W surge margin is sufficient and through-hole mounting is not required. |
| 1.5KE30A-E3/54 | Same electrical specs and DO-201AD package, but commercial-grade (non-AEC-Q101), E3 suffix only | Lacks automotive qualification; not approved for under-hood or safety-critical vehicle subsystems | Use for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated. |
Compared with SMBJ30A and 1.5KE30A-E3/54, the 1N6282AHE3_B/C uniquely combines 1500 W surge capability, AEC-Q101 qualification, and axial-leaded DO-201AD packaging - making it the only option among the three qualified for automotive power rail protection requiring both high energy absorption and automotive reliability validation.

FAQ
What is the breakdown voltage range of the 1N6282AHE3_B/C?
The 1N6282AHE3_B/C has a specified breakdown voltage (VBR) range of 28.5 V to 31.5 V at a test current of 1.0 mA. This tight ±5% tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in 24 V and 36 V systems where margin above nominal rail voltage must be tightly controlled.
Is the 1N6282AHE3_B/C qualified for automotive use?
Yes, the 1N6282AHE3_B/C carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay documentation. It is approved for automotive applications including engine control units, body control modules, and infotainment power supplies - validated for temperature cycling, humidity resistance, and mechanical shock per AEC-Q101 test conditions.
What is the clamping voltage of the 1N6282AHE3_B/C at its rated peak pulse current?
The 1N6282AHE3_B/C clamps to a maximum of 41.4 V at its rated peak pulse current (IPPM) of 36.2 A, measured using the standard 10/1000 µs double-exponential waveform. This value directly determines the maximum voltage stress imposed on downstream components during surge events and is critical for ensuring compatibility with 3.3 V, 5 V, and 24 V ICs.
Does the 1N6282AHE3_B/C have a bidirectional variant?
No - the 1N6282AHE3_B/C is strictly unidirectional. Bidirectional variants in the same voltage grade use the "CA" suffix (e.g., 1.5KE30CA), and Vishay's documentation confirms bidirectional types are only offered from 1.5KE6.8CA to 1.5KE220CA. The "A" suffix in 1N6282AHE3_B/C explicitly denotes unidirectional polarity with cathode band marking.
What package type does the 1N6282AHE3_B/C use, and what are its key mechanical properties?
The 1N6282AHE3_B/C uses the DO-201AD package (Case Style 1.5KE): axial-leaded, 5.3 mm diameter × 9.5 mm length molded epoxy body with UL 94 V-0 flammability rating. Leads are matte tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance - essential for high-reliability industrial and automotive assembly processes.
