That sub-50 ns recovery makes it suitable for high-frequency rectification in flyback converters, PFC boost stages, and snubber clamps where stored charge in a standard recovery diode would cause excess dissipation or ringing. At 1.5 A average forward current and 200 V reverse voltage, it fits 48 V to 120 V DC rails with margin. ## Through-hole DO-15 axial — legacy footprint, still serviceable Packaged in a DO-204AC (DO-15) axial-lead through-hole case, the STTH152 is a PTH part suited for point-to-point wiring, terminal block rectifier assemblies, or retrofit into older boards that use axial diodes. Junction temperature rating reaches 175 °C max, which gives margin in high-ambient or poorly ventilated enclosures. ## Forward drop and leakage at rated conditions Forward voltage is specified at 950 mV maximum when forward current is 1.5 A. Reverse leakage is 1.5 µA at the rated 200 V reverse voltage. These numbers are typical for a fast recovery diode in this voltage and current class — the leakage stays low enough to avoid thermal runaway in lightly loaded standby circuits.","metaTitle":"STTH152 Fast Recovery Diode, 200 V, 1.5 A, 32 ns trr, DO-15","metaDescription":"STTH152 fast recovery diode: 200 V, 1.5 A, 32 ns trr, DO-15 axial.
