Overview
The TPM2003C-SO3R is a high-voltage, high-current Darlington bipolar junction transistor array manufactured by 3PEAK. It integrates seven independent low-side NPN channels designed for driving inductive loads. Each channel features an integrated freewheeling diode to manage reverse voltage spikes. The device supports a maximum drain current of 500mA per channel and operates with a supply voltage up to 50V. It is housed in a 16-SOP package.
Feature Summary
- Integrates seven independent low-side NPN Darlington channels for parallel or individual load control
- Includes built-in freewheeling diodes on each output to protect against inductive kickback
- Designed for high-voltage operation suitable for automotive and industrial switching applications
Applications
- Automotive lighting systems including headlamps and interior illumination
- Industrial motor control circuits requiring low-side switching
- Solenoid and relay driver interfaces in heavy machinery
- High-power LED arrays and indicator circuits
Procurement Notes
Verify the exact part marking matches TPM2003C-SO3R to distinguish from similar variants like TPM2003-SO3R. Confirm the manufacturer is 3PEAK (Si Rui Pu) as counterfeits exist. Request the official datasheet to validate electrical characteristics such as leakage current and saturation voltage before finalizing procurement orders.
Selection Notes
Select this component when multiple low-side switches are required in a compact form factor. It is suitable for applications needing high current capability per channel without external discrete transistors. Ensure the thermal management design accounts for power dissipation across all active channels simultaneously.
Part Context
This part belongs to the 3PEAK power driver family, focusing on robust switching solutions for demanding environments. It complements other gate drivers and power ICs offered by the manufacturer, providing a specialized solution for multi-channel inductive load control in automotive and industrial sectors.
Replacement Considerations
Check for direct substitutes within the same product line. Verify pin compatibility and electrical ratings if considering alternatives from other manufacturers. Ensure any replacement maintains the seven-channel configuration and integrated diode protection.
