3. SOD-123 Design Considerations SOD-123
-SOD-123 heat dissipation optimization SOD-123: High power applications require an increase in PCB copper foil area or heat dissipation vias to avoid junction temperature exceeding limits.   
-SOD-123 current limiting resistor matching SOD-123: The series resistance value needs to be calculated based on the load current to ensure that the operating current is ≤ 39mA (conservatively estimated at 500mW/15V).

4、 Series comparison and selection
Changdian Technology provides SOD-123BZT52C15SSOD-123 (SOD-323 package, 200mW) as a complementary model, suitable for low-power scenarios with limited space (such as wearable devices). The standard BZT52C15 has become the preferred choice for medium to high power scenarios with a power of 500mW. Both have the same voltage regulation characteristics, and engineers can flexibly select based on heat dissipation conditions and layout density.
5、 Summary
Changdian BZT52C15 is an ideal choice for industrial and automotive electronics fields, with SOD-1235V precise voltage stabilization SOD-123, SOD-123500mW power capacity SOD-123, and SOD-123 package reliability SOD-123. Its advantages in balancing performance and cost make it particularly suitable for power and protection circuit designs that require long-term stable operation. For ultra compact scenarios, the BZT52C15S can be downgraded to form a complete 15V voltage stabilization solution matrix.
