Engineering Selection Recommendations

MBR1635-E3/45 Substitution Basis:

The MBR1635-E3/45 qualifies as a direct substitute for the MBR735 based on electrical and mechanical compatibility within the TO-220AC package form factor. Both components are Active product status with ROHS3 compliance certification. The MBR1635-E3/45 provides increased current capacity (16A versus 7.5A) and lower forward voltage drop (630 mV @ 16A versus 840 mV @ 15A), delivering enhanced thermal efficiency and current handling margin. The extended junction temperature minimum (-65°C versus -55°C) provides broader operating range coverage. Reverse leakage current is higher in the substitute (200 µA versus 100 µA at 35V), remaining within acceptable Schottky diode performance parameters. Both components maintain identical fast recovery switching characteristics and package pinout compatibility, enabling direct board-level replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the MBR1635-E3/45 be used as a direct replacement for the MBR735 in existing circuit designs?

A: Yes. Both components share identical TO-220AC package pinout, voltage rating (35V), and fast recovery Schottky technology. The MBR1635-E3/45 exceeds the MBR735 current specification (16A versus 7.5A), making it electrically compatible for direct substitution without circuit redesign.

Q: What are the key electrical differences between these two diodes?

A: The primary differences are current rating (MBR1635-E3/45 rated 16A versus MBR735 at 7.5A) and forward voltage drop (630 mV @ 16A versus 840 mV @ 15A). The MBR1635-E3/45 exhibits lower forward voltage, reducing power dissipation. Reverse leakage current is higher in the substitute (200 µA versus 100 µA at 35V).

Q: Are both components RoHS compliant?

A: Yes. Both the MBR735 and MBR1635-E3/45 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for industrial and commercial applications.

Q: What is the operating temperature range for each component?

A: The MBR735 operates from -55°C to 150°C junction temperature. The MBR1635-E3/45 extends the minimum to -65°C, providing broader low-temperature performance capability while maintaining the same 150°C maximum.

Q: Can these diodes be used interchangeably in high-frequency switching applications?

A: Yes. Both components feature identical fast recovery switching characteristics (≤ 500ns, > 200mA Io), qualifying them for equivalent performance in high-frequency rectification and switching circuits.

Q: What packaging format is used for both components?

A: Both the MBR735 and MBR1635-E3/45 are supplied in Through Hole TO-220-2 package (TO-220AC supplier device package), enabling direct board-level mounting compatibility.
