PVT312

PVT312 Description

The PVT312 from Infineon Technologies is a high-performance Solid State Relay (SSR) designed for switching AC or DC loads up to 250V with a load current of 190 mA. Part of the PVT series under the HEXFET® family, this SPST-NO (Single-Pole Single-Throw, Normally Open) relay offers reliable low-power switching with an on-state resistance of 10 Ohms (max). Its through-hole PC pin termination ensures secure mounting, while the 1.2VDC input voltage makes it compatible with low-voltage control circuits. Although marked as obsolete, it remains a robust choice for legacy systems due to its REACH Unaffected compliance and Moisture Sensitivity Level (MSL) 1 rating, indicating unlimited shelf life.

PVT312 Features

• Dual Output Compatibility: Supports both AC and DC load switching (0–250V).
• Low Control Voltage: Operates at 1.2VDC, ideal for energy-sensitive applications.
• High Reliability: HEXFET® technology ensures low on-resistance (10Ω max) and minimal power dissipation.
• Robust Construction: Through-hole mounting and PC pin termination enhance mechanical stability.
• Compliance: EAR99 (Export Controlled) and HTSUS 8536.41.0030 certified for global use.
• Obsolete but Durable: Despite discontinuation, its unlimited MSL and tube packaging ensure long-term usability.

PVT312 Applications

• Industrial Automation: Low-voltage control of sensors, solenoids, or small actuators.
• Test & Measurement Equipment: Precision switching in benchtop instruments.
• Legacy Electronics: Retrofitting older systems requiring AC/DC SSR functionality.
• Low-Power Circuits: Battery-operated devices where 1.2VDC input minimizes energy consumption.
• HVAC Systems: Auxiliary control for fans or dampers within 250V limits.

Conclusion of PVT312

The PVT312 stands out for its versatile AC/DC switching, low control voltage, and HEXFET® efficiency, making it a dependable choice for low-power industrial and electronic applications. While obsolete, its durability and compliance ensure continued utility in legacy designs. Engineers seeking a compact, through-hole SSR with broad voltage range compatibility will find this model particularly advantageous.
