Compatibility & Fitment

• Suitable for TV, FM, and AM radio detection circuits
• Commonly used in crystal radio sets and DIY electronics
• Designed for switch-mode power supplies and high-frequency DC-to-DC converters
• Often used as a modern substitute for Germanium diodes in audio circuits and effects pedals

When to Replace

• Diode fails an open-circuit test with a multimeter
• Diode fails a short-circuit test (shows continuity in both directions)
• Incorrect voltage output or signal clipping in the circuit
• Component shows visible signs of heat damage or physical cracking

Installation Tips

• Identify the cathode band (stripe) to ensure correct polarity during installation. The band indicates the negative terminal.
• Use a low-wattage soldering iron to prevent thermal damage to the component.
• To dissipate heat, attach a heat sink (e.g., an alligator clip) to the lead between the diode body and the solder joint.
• Avoid bending leads too close to the glass body to prevent stress fractures.
• Always verify the diode's orientation against the circuit board markings or schematic before soldering.
