Diode THT DO-36 200V 0.25A axial lead — general-purpose rectifier

The Diode THT DO-36 200V 0.25A axial lead — general-purpose rectifier is a through-hole axial diode designed for common rectification and polarity control tasks in small electronic assemblies. Housed in a DO-36 glass package with axial leads, it provides up to 200 volts of reverse voltage protection and handles continuous forward currents up to 0.25 amperes. The component is intended for repair, prototyping and low-current designs where a compact, reliable diode is required.

Advantages

This axial lead diode offers a compact DO-36 package that is easy to mount on perfboards and PCB through-hole pads. Its 200 V reverse voltage rating and 0.25 A forward current capability make it suitable for a range of low-power rectification and blocking applications. The glass-encapsulated body provides visible inspection of the junction and stable mechanical leads for soldering or wave solder processes. The design supports dependable polarity protection and basic transient handling in consumer and industrial hobby circuits.

Suitable for

• Repairing or replacing diodes in through-hole electronic equipment
• Prototyping low-current power supplies and rectifier stages
• Signal blocking and polarity protection in sensors and controllers
• Educational electronics and hobbyist circuit assemblies

Key specifications

• Package type: DO-36 axial glass package
• Maximum reverse voltage: 200 V
• Maximum forward current (continuous): 0.25 A
• Mounting style: Through-hole axial leads
• Typical applications: General-purpose rectification, blocking, polarity protection

How to use

Install the diode with correct polarity so the cathode and anode match the circuit orientation; the cathode is normally marked on the body. Solder the axial leads into through-hole pads or a perfboard, taking care to avoid excessive heat that could damage the glass package. Observe the specified maximum reverse voltage and forward current ratings during operation; use appropriate heat sinking or current limiting if the diode will conduct near its maximum continuous current. For prototyping, verify circuit behavior under expected supply voltages before finalizing the layout.

Usage recommendations

For reliable long-term performance, avoid sustained operation at the diode's maximum ratings without adequate thermal management. When used for rectification in power circuits, consider a diode with higher current or peak reverse voltage ratings if transient conditions or inrush currents may exceed 0.25 A or 200 V.
