Overview
The 2N6073B is a bidirectional triac manufactured by Central Semiconductor Corp, designed for through-hole mounting in the TO-225-3 package. It features a rated repetitive off-state voltage (VDRM) of 400 V and supports a non-repetitive peak on-state current of 30 A. The device operates within a junction temperature range of -40 °C to +110 °C. Key electrical characteristics include a maximum holding current of 15 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 5 mA. The on-state voltage is specified at 2 V, with a maximum off-state leakage current of 10 µA under VDRM conditions.
Feature Summary
- Bidirectional switching capability for AC control applications
- Robust thermal performance with a maximum operating temperature of +110 °C
- High surge current handling capacity suitable for inductive loads
Applications
- AC motor speed control circuits
- Solid-state relay implementations
- Lighting dimmer systems
Procurement Notes
Verify the specific manufacturer designation as the 2N6073B part number is historically associated with onsemi. Confirm that the Central Semiconductor variant matches the required pinout and electrical tolerances. Request the official datasheet to validate RoHS compliance status and ensure the tin/lead finish meets solderability requirements for the intended assembly process.
Selection Notes
Select this component when a 400 V bidirectional switch is required in a TO-225-3 form factor. Ensure the circuit design accounts for the 15 mA holding current threshold to prevent unintended turn-off. Verify that the gate drive circuit can supply at least 5 mA at 2.5 V to guarantee reliable triggering across the specified temperature range.
Part Context
This device belongs to the thyristor family, specifically categorized as a triac. It serves as a semiconductor switch for alternating current, replacing mechanical relays in many low-to-medium power applications. The TO-225-3 package provides a standardized footprint for through-hole integration into printed circuit boards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 400 V, 4 A class triacs in TO-225 packages only after verifying exact pin compatibility and thermal resistance parameters.
