Overview
The CTLM3410-M832D is a dual NPN silicon transistor from Central Semiconductor Corp, housed in a TLM832D surface mount package. It features a collector-base voltage of 40 V and a collector-emitter voltage of 25 V. The device supports a continuous collector current of 1.0 A with a power dissipation rating of 1.65 W. Thermal resistance (ΘJA) is 76 °C/W. Saturation voltage (VCE(SAT)) ranges from 25 mV to 450 mV depending on the collector current. Transition frequency (fT) reaches 100 MHz.
Feature Summary
- Dual chip configuration providing two NPN transistors within a single leadless surface mount footprint.
- Low saturation voltage design optimized for high operational efficiency and minimal energy consumption.
- High power-to-footprint ratio achieved through a thermally efficient Tiny Leadless Module (TLM) case.
Applications
- Switching circuits
- DC-DC converters
- LCD backlighting systems
- Battery-powered portable equipment
Procurement Notes
Verify component authenticity by checking the marking code 'CFG' against the datasheet specifications. Confirm that the package matches the TLM832D mechanical outline. Ensure the supplier provides traceability documentation consistent with Central Semiconductor Corp standards before finalizing acquisition.
Selection Notes
Select this component when space constraints require a dual NPN configuration in a compact surface mount form factor. Evaluate the thermal performance based on the 76 °C/W junction-to-ambient resistance and the required copper mounting pad area of 54 mm². Verify that the 25 V collector-emitter voltage meets the circuit's maximum operating requirements.
Part Context
This part belongs to a series including the CTLM7410-M832D (dual PNP) and CTLM3474-M832D (complementary). All variants share the same TLM832D package dimensions and thermal characteristics while differing in semiconductor polarity and internal transistor arrangement.
Replacement Considerations
Official replacement data indicates no direct substitute is available. The manufacturer lists this specific part number as having no alternative product mapping in their discontinuation notices.
