Case study: Customer looking for a TO-247 solution with 1600V, 20A and Trr = 300ns
A customer reached out to Diotec Electronics Corporation looking for a TO-247 solution with 1600V, 20A and Trr = 300ns to energize a solenoid for < 100ms. The customer had a project in its early stages and was in the process of having a prototype built.
The customer’s main goal was to find a package that had enough thermal mass (without a heatsink) to absorb the heat of a one-time 100ms pulse without overheating the die (pulse may repeat every 30 seconds).
Solution: Tab-mounted button diode package (TO-220AC equivalent)
Diotec Electronics Corporation specializes in designing diode cell and diode cell package combinations that serve our customer’s unique technical needs and offer the highest performance. Diotec Electronics Corporation’s recommendation for this customer is a tab-mounted button diode package (TO-220AC equivalent) given the customer’s need for performance, cost efficiency related to tooling, and lead time.
Button diode with a 250 mils diameter round die
Diotec Electronics Corporation "button" diode equipped with a 250 mils diameter round die with Vbr ~1800V and Trr ~ 300nS could meet the customer’s head transfer and dissipation requirements. We recommended the largest possible die size that can fit in the package to achieve the lowest possible forward voltage (VF). 100% of die surfaces are soldered to silver-plated copper headers, which offers much superior electrical and heat transfer, while also better handling thermal and mechanical stresses.
Tab-mounted button diode package
The customer’s key design considerations were high heat dissipation and operation without an external heat sink. Diotec Electronics Corporation’s tab-mounted button diode package, in combination with a big diode die, provides great heat transfer and heat dissipation efficiency that meets the customer’s requirements.
