Product details

Overview

1N6283A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 31.4 V to 34.7 V breakdown voltage (V_BR) at 1.0 mA test current, 28.2 V maximum standoff voltage (V_WM), 45.7 V clamping voltage (V_C) at 32.8 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 transients and inductive switching surges.

For engineers reviewing the 1N6283A-E3/54 datasheet, 1N6283A-E3/54 pinout, 1N6283A-E3/54 application, or 1N6283A-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under surge conditions, thermal derating behavior, and direct alternatives for circuit protection design-in.

Technical Context

This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds V_BR, it avalanches into low-impedance conduction to divert surge current away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and fast response (<1 ns), while the 1.5KE molded epoxy package provides UL 94 V-0 flammability compliance and robust mechanical integrity.

The device supports 200 A non-repetitive forward surge current (I_FSM) and exhibits 0.098 %/°C temperature coefficient of V_BR. Thermal resistance is 75 °C/W (junction-to-ambient) and 15.4 °C/W (junction-to-lead), enabling predictable power dissipation management up to 175 °C maximum junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR (min/max)	31.4 V / 34.7 V at 1.0 mA - defines precise avalanche initiation threshold for reliable overvoltage detection
V_WM	28.2 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA
V_C @ I_PPM	45.7 V at 32.8 A - clamped voltage during 1500 W surge, limiting stress on protected ICs
P_PPM	1500 W - peak pulse power handling with 10/1000 µs waveform, suitable for IEC 61000-4-5 Level 4 compliance
I_FSM	200 A - single half-sine surge current capability (8.3 ms), critical for motor drive and relay coil suppression
T_J max.	175 °C - enables operation in under-hood automotive or industrial power supply environments
R_θJA	75 °C/W - determines required PCB copper area or heatsinking for sustained 6.5 W power dissipation

Pinout & Package

1N6283A-E3/54 uses the standard axial-leaded JEDEC Case Style 1.5KE package: molded epoxy body with matte tin-plated leads, 0.375" (9.5 mm) lead length, and cathode band marking. The device has two terminals: anode and cathode - polarity is unidirectional, with the banded end indicating the cathode.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry point during forward conduction	Connected to ground or low-side reference in clamp-to-rail configurations
Cathode (banded end)	Current exit point during avalanche conduction	Connected to protected line (e.g., +12 V rail); clamps transients to V_C relative to anode

Key Features

Feature	Design Value
Glass-passivated junction	Ensures stable V_BR tolerance and long-term reliability under repeated surge stress
1500 W peak pulse power (10/1000 µs)	Meets IEC 61000-4-5 surge immunity requirements for industrial and automotive power inputs
Clamping voltage ≤ 45.7 V at 32.8 A	Protects 3.3 V/5 V/12 V logic and power ICs by limiting transient overshoot within safe margin
Response time < 1 ns	Acts before sensitive semiconductor junctions experience destructive overvoltage
UL 94 V-0 compliant epoxy case	Prevents flame propagation in safety-critical enclosures per regulatory standards

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ33A	Lower P_PPM (600 W), smaller SMB package (surface-mount), V_BR = 36.7–40.6 V, V_C = 53.3 V @ 11.2 A	Designed for PCB space-constrained layouts; less suited for high-energy 1500 W surges	Select when board area is limited and surge energy does not exceed 600 W; verify thermal relief for SMB footprint.
1.5KE33A	Same electrical specs and 1.5KE package; differs only in packaging suffix (E3/54 vs. standard E3 tape-and-reel)	No functional difference - identical die, construction, and performance	Choose 1.5KE33A for standard reel delivery; 1N6283A-E3/54 is functionally identical but supplied in 13" paper tape with 1400-unit reels.

Compared with SMBJ33A, 1N6283A-E3/54 delivers 2.5× higher surge power handling and superior thermal dissipation via axial leads, while 1.5KE33A offers identical protection performance in alternate packaging - making 1N6283A-E3/54 optimal for high-reliability through-hole designs requiring full 1500 W capability.

FAQ

What is the breakdown voltage range of the 1N6283A-E3/54?

The 1N6283A-E3/54 has a guaranteed breakdown voltage (V_BR) range of 31.4 V to 34.7 V at 1.0 mA test current, measured per JEDEC standards. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in circuits protecting 24 V or 36 V systems. The value is confirmed in Vishay's official datasheet document 88301, revision 09-Aug-2022.

Is the 1N6283A-E3/54 RoHS compliant and qualified for automotive use?

Yes, the 1N6283A-E3/54 carries the E3 suffix, indicating RoHS compliance and commercial-grade qualification. While it is not AEC-Q101 qualified (which requires HE3 suffix), its glass-passivated junction, 175 °C max junction temperature, and robust surge ratings make it widely deployed in non-safety-critical automotive subsystems such as body control modules and infotainment power rails. For AEC-Q101 compliance, specify 1N6283AHE3_B instead.

How does the clamping voltage of the 1N6283A-E3/54 compare to its breakdown voltage?

The 1N6283A-E3/54 clamps at 45.7 V when subjected to its rated 32.8 A peak pulse current (10/1000 µs waveform), which is approximately 31 % above its minimum V_BR of 31.4 V. This incremental clamping voltage (ΔV_C = 14.3 V) reflects low dynamic impedance during avalanche, ensuring effective protection without excessive overshoot - critical for safeguarding 36 V-rated ICs and MOSFETs.

Can the 1N6283A-E3/54 be used in bidirectional configurations?

No, the 1N6283A-E3/54 is strictly unidirectional, as indicated by the "A" suffix and cathode band marking. Bidirectional variants in the same family use the "CA" suffix (e.g., 1.5KE33CA). Using 1N6283A-E3/54 in reverse-biased configurations will result in forward conduction (~3.5 V drop) rather than symmetrical clamping - so it must be oriented with cathode toward the protected line and anode to ground.

What is the thermal resistance and maximum power dissipation of the 1N6283A-E3/54?

The 1N6283A-E3/54 has a typical junction-to-ambient thermal resistance (R_θJA) of 75 °C/W and a maximum steady-state power dissipation (P_D) of 6.5 W at T_L = 75 °C on an infinite heatsink. In practical PCB layouts, derating is required above 25 °C ambient - e.g., at 75 °C ambient, usable P_D drops to ~3.25 W. These values are validated in Vishay's thermal characterization curves (Fig. 5) and essential for thermal design of high-duty-cycle protection circuits.
