Description
Product Details

BDV67D Power Darlington Transistor - Heavy-Duty Load Switching & Motor Control

The BDV67D is a robust NPN Darlington transistor designed for applications requiring high current handling and substantial power dissipation. Its two-transistor structure delivers exceptional current gain (hFE), enabling control of large motors, solenoids and relay coils with minimal base drive current—ideal for industrial automation and power electronics.

Functions & Applications

Massive Current Gain (hFE): Darlington configuration delivers extremely high β, allowing control of heavy loads with minimal base current.
High-Power TO-247 Package: Direct thermal path to heatsink for reliable cooling during continuous operation.
Motor & Solenoid Ready: Capable of switching large inductive loads; use a flyback diode for protection.
Robust Collector-Emitter Voltage: Suitable for industrial switching and power control circuits.

Frequently Asked Questions

Q: Does the BDV67D require a heatsink?
A: Yes, strongly recommended. Darlingtons have a higher internal voltage drop (typically ~1.5V base-emitter), so they dissipate significant heat at high collector currents. A heatsink is essential for reliable operation.

Q: Can the BDV67D drive a 24V DC motor?
A: Yes, the BDV67D is designed for such applications. Always use a free-wheeling (flyback) diode across inductive loads to suppress voltage spikes and protect the transistor.

Notes

High internal Vbe drop (~1.5V) typical for Darlington structure. Heatsink strongly recommended for sustained high-current operation. Requires flyback diode for inductive loads.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
