Triacs datasheet and documents for OT391,412
Triacs Overview
The WeEn Semiconductors OT391,412 is a silicon avalanche-rated Zener diode designed for transient voltage suppression and voltage reference applications. It features a nominal breakdown voltage of 39V with a maximum DC dynamic impedance of 10 ohms at a test current of 5mA. The device is rated for a maximum power dissipation of 500mW in free air and can withstand a peak pulse power of 1.5kW under specified conditions (8/20µs waveform). It operates within a junction temperature range of -55°C to +175°C and utilizes a compact SOD-123 surface-mount package.
Triacs Feature Summary
- Avalanche-rated construction ensures robustness against repetitive surge events
- High thermal stability supports operation up to 175°C junction temperature
- Low dynamic impedance provides stable voltage regulation under varying currents
Triacs Applications
- Transient voltage suppression in electronic circuits
- Voltage reference sources for precision analog designs
- Overvoltage protection for sensitive semiconductor components
Triacs Procurement Notes
Verify the specific ordering code suffix to confirm the tape-and-reel quantity and packaging format. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders. Ensure storage conditions align with moisture sensitivity level requirements for surface-mount devices.
Triacs Selection Notes
Select this component when a 39V breakdown voltage is required for clamping or referencing. Consider the 500mW power rating and SOD-123 footprint constraints during PCB layout. Evaluate the thermal resistance characteristics if multiple units are placed in close proximity on the board.
Triacs Part Context
This part belongs to the standard Zener diode portfolio from WeEn Semiconductors, formerly NXP's Standard Products division. It serves as a fundamental discrete semiconductor component for general-purpose protection and regulation tasks across industrial and consumer electronics sectors.
Triacs Replacement Considerations
Equivalent parts include the BZX5C39 from NXP and the PZU39B from Diodes Incorporated. Verify pinout compatibility and exact tolerance grades before substitution.
