Product details
Overview
1N6289A-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 53.2–58.8 V breakdown voltage (VBR), 47.8 V standoff voltage (VWM), 77.0 V clamping voltage at 19.5 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1N6289A-E3/54 datasheet, 1N6289A-E3/54 pinout, 1N6289A-E3/54 application, or 1N6289A-E3/54 equivalent, this device serves as a high-energy, fast-response (≤1 ns), glass-passivated unidirectional TVS for industrial power supplies, automotive body electronics, and telecom interface protection where robust 1.5 kW surge handling and low clamping ratio are critical.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve stable breakdown characteristics and low incremental surge resistance. Its 10/1000 µs waveform rating supports repetitive surge events at 0.01% duty cycle, with thermal resistance of 15.4 °C/W (junction-to-lead) enabling reliable operation under transient stress without heatsinking.
The device exhibits a forward voltage of 3.5 V at 100 A (per spec note 3), confirming suitability for high-current clamp paths, and its temperature coefficient of VBR is +0.103 %/°C - enabling predictable voltage drift across wide ambient ranges. Polarity is marked by a cathode band, consistent with standard DO-201AE package orientation.
Key Specifications

FAQ
What is the breakdown voltage tolerance of the 1N6289A-E3/54?
The 1N6289A-E3/54 has a specified breakdown voltage range of 53.2 V to 58.8 V at 1.0 mA test current (IT), representing a ±5.2% tolerance around the nominal 56 V rating. This tight VBR window ensures consistent clamping onset across production lots and supports precise overvoltage margin design in 48 V systems.
Is the 1N6289A-E3/54 suitable for bidirectional transient protection?
No, the 1N6289A-E3/54 is strictly a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in its designation. Bidirectional variants (e.g., 1N6289CA) exist in the same family but are distinct orderable parts. Using 1N6289A-E3/54 for AC or dual-polarity lines would result in forward conduction during negative half-cycles.
What is the maximum clamping voltage of the 1N6289A-E3/54 under surge conditions?
The 1N6289A-E3/54 clamps to a maximum of 77.0 V when subjected to its rated 19.5 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet and reflects worst-case device behavior at TA = 25 °C - actual clamping may be slightly lower at elevated temperatures due to positive VBR tempco.
Does the 1N6289A-E3/54 meet automotive qualification standards?
The 1N6289A-E3/54 is a commercial-grade part with RoHS-compliant E3 termination and JESD 201 Class 1A whisker resistance, but it is not AEC-Q101 qualified. For automotive applications requiring qualification, the functionally identical 1.5KE56AHE3_A (or 1N6289AHE3_A) should be selected - it shares all electrical parameters but adds AEC-Q101 stress testing and enhanced process controls.
How is thermal performance characterized for the 1N6289A-E3/54?
The 1N6289A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W and junction-to-ambient (RθJA) of 75 °C/W. This means that under short-duration surge conditions, heat dissipates efficiently through the leads into the PCB copper, allowing reliable operation without heatsinking - validated up to 175 °C maximum junction temperature.
