Overview
The MC1413BD is a high-voltage, high-current Darlington transistor array manufactured by onsemi. It integrates seven NPN Darlington-connected transistors within a single SOIC-16 package. Each channel includes an internal 2.7 kΩ series input resistor and a clamp diode for inductive load suppression. The device supports a maximum continuous collector current of 500 mA and a collector-emitter breakdown voltage of 50 V. It operates reliably across an ambient temperature range of -40°C to +85°C.
Feature Summary
- Integrates seven NPN Darlington pairs with built-in 2.7 kΩ base resistors for direct TTL/CMOS interfacing
- Includes internal suppression diodes to protect against inductive load back-EMF
- Supports peak inrush currents up to 500 mA suitable for driving incandescent lamps
Applications
- Driving relays in industrial control systems
- Actuating printer hammers in office equipment
- Switching incandescent lamps in consumer electronics
Procurement Notes
Verify the specific suffix 'BD' indicates the SOIC-16 rail packaging format when sourcing. Confirm that the component meets the required Pb-Free specifications if environmental compliance is mandatory for the assembly process. Ensure the operating temperature range aligns with the system's thermal design requirements.
Selection Notes
Select this component when multiple high-side switching channels are required in a compact surface-mount footprint. The integrated input resistors simplify logic interface design by eliminating external components. Consider the 50V rating for moderate voltage loads and verify that the 500mA per-channel limit accommodates the connected load current.
Part Context
This part belongs to the MC1413 family of high-voltage Darlington arrays from onsemi. It shares functional characteristics with the MC1413D (SOIC) and MC1413P (PDIP) variants, differing primarily in the physical package type. The 'B' designation typically denotes the extended low-temperature operating range compared to standard versions.
Replacement Considerations
Direct pin-compatible alternatives include the MC1413DR2G and MC1413DG. For lead-free requirements, the MC1413BDG is available. Verify that substitute parts maintain the same 500mA current rating and 50V breakdown voltage.
