Descripción general

Description

1.5KE440A is a TVS diode from the 1.5KE (1.5 kW peak pulse power) family used to protect circuits from voltage transients (surges, ESD, inductive kick). It clamps excess voltage to keep other components safe.
Key points:
- Peak pulse power: about 1.5 kW (8/20 µs waveform).
- Voltage rating: the “440” indicates a nominal high-voltage region around 440 V; the device has a reverse standoff in hundreds of volts and a breakdown/clamp behavior around that range (values vary with current and temperature).
- Variant: the “A” suffix denotes the standard variant; other suffixes (e.g., B/C) indicate different configurations (often bidirectional vs unidirectional). Check the datasheet for exact behavior.
Typical use:
- Protect power-supply inputs, DC links, motor drives, telecom lines, and other circuitry from voltage spikes.
Note:
- Always reference the manufacturer’s datasheet for exact Vrwm, Vbr, clamp voltage, packaging, and derating with temperature.

Package

1.5KE440A is a high‑power TVS diode. The classic package is through‑hole axial (DO‑41) with axial leads; surface‑mount SMB/SMC variants are also available from some vendors.

Pinout

- Pin count: 2 terminals (two-terminal device: anode and cathode).
- Function: a 1.5 kW peak surge transient-voltage suppressor diode with a reverse standoff of ~440 V (unidirectional, 1.5KE440A). It clamps high-voltage transients to protect circuits.

Manufacturer

- Manufacturer: Littelfuse, Inc.
- What kind of company: An American multinational that designs and manufactures circuit-protection devices, including fuses, transient voltage suppressors (TVS diodes), surge suppressors, and related components.

Application

1.5KE440A is a high-energy transient-voltage suppressor (TVS) diode for surge protection (≈1.5 kW peak pulse, 440 V stand-off). Applications: protect high-voltage power circuits from transients—380–480 VAC input and 600+ V DC bus; SMPS, motor drives, solar inverters, and energy-storage systems; telecom/industrial power rails and automotive HV charging circuits.
