TRACOPOWER Switching Regulator, Through Hole, 5V DC Output, 1A, 83% Efficiency, SIP Package TSRN 1-2450

The TRACOPOWER TSRN 1-2450 is a compact, high-efficiency switching regulator designed to provide a stable 5V DC output at currents up to 1A. Featuring a single in-line package (SIP) and through hole mounting, this regulator is engineered for convenient integration into a variety of electronic circuits, especially where board space is limited and low-profile solutions are necessary.

This model supports a wide input voltage range from 6.5V DC to 42V DC, making it ideal for diverse industrial automation and power supply scenarios. Its high efficiency of up to 83% means reduced thermal dissipation, so no additional heat sink is needed during normal operation, which further simplifies PCB design. The output exhibits minimal ripple and noise - only 50mV peak-to-peak - ensuring stable performance for sensitive loads such as precision control circuits and analogue front-ends.

The robust plastic housing enhances mechanical durability, sustaining impact and abrasion in demanding environments. Operating reliably over an extended temperature range of -40°C to +85°C, the TSRN 1-2450 includes short-circuit and overtemperature protection circuitry. The UL 94 V-0 rated silicone potting self-extinguishes rapidly in fault scenarios, contributing to elevated workplace safety.

Designed for industrial, transportation, and automation applications, this regulator complies with EN 61373 for use in railway electronic equipment. It is especially suited for applications including distributed power supply systems, embedded computer supplies, and powering automation logic modules and communication equipment where tight voltage regulation and high MTBF are critical. The unit is rated for a mean time between failures (MTBF) of up to 6,000,000 hours, reflecting its suitability for mission-critical deployments demanding consistent reliability.

Key dimensions are 11.7mm by 7.5mm by 10.2mm (L×W×D), making this SIP switching regulator easy to place even in dense PCB layouts. The package design supports easy assembly and maintenance, further aided by its single fixed 5V output and thru-hole geometry. Compliance with international standards such as RoHS ensures suitability for projects requiring environmental responsibility as well as technical performance.
