Diodes Incorporated MBR30H100CTF-E1

Overview

MBR30H100CTF-E1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220F-3 package, rated for 100 V reverse voltage, 15 A average forward current per diode leg (30 A total), and 0.8 V max forward voltage at 15 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification.

For engineers reviewing the MBR30H100CTF-E1 datasheet, MBR30H100CTF-E1 pinout, MBR30H100CTF-E1 application, or MBR30H100CTF-E1 equivalent, key selection criteria include its 175°C junction temperature rating, 250 A non-repetitive surge capability, guard-ring stress protection, RoHS-compliant lead-free finish, and thermal resistance of 2.5°C/W (junction-to-case).

Technical Context

This dual Schottky rectifier integrates two independent anode terminals (A1, A2) sharing a common cathode (K), enabling synchronous or interleaved rectification in center-tapped or dual-output topologies. Its low VF and fast recovery eliminate minority-carrier storage delay, making it suitable for >100 kHz switching converters.

The device uses a planar epitaxial structure with guard-ring passivation to suppress edge breakdown at high dv/dt (10,000 V/µs). Thermal performance is optimized for mounting on heatsinks via its insulated TO-220F-3 case, delivering 2.5°C/W RθJC under recommended pad layout.

FAQ

Is MBR30H100CTF-E1 pin-compatible with MBR30H100CT-E1?

Yes-both share identical TO-220 pinout (A1-K-A2) and internal dual-Schottky structure. The only difference is package type: MBR30H100CTF-E1 uses insulated TO-220F-3 (flange electrically isolated), while MBR30H100CT-E1 uses standard TO-220-3 (flange connected to cathode). Mounting hardware and heatsink isolation requirements differ accordingly.

What is the maximum recommended case temperature for continuous operation?

The datasheet specifies IF(AV) = 15 A per leg at TC = +162°C. For reliable long-term operation, Diodes recommends limiting TC to ≤ +135°C to maintain >10-year lifetime under typical thermal cycling. Derating curves in Figure 4 confirm 12 A per leg is sustainable at TC = +150°C.

Does MBR30H100CTF-E1 require a minimum load or snubber network?

No minimum load is required. A snubber is not needed due to the Schottky's zero-recovery behavior and inherent dv/dt tolerance (10,000 V/µs). However, a small RC snubber (e.g., 100 Ω + 100 pF) may be added across each anode–cathode if ringing is observed above 50 MHz in ultra-high-frequency designs.

Can MBR30H100CTF-E1 be used in synchronous rectification circuits?

No-it is a passive Schottky rectifier, not a controlled switch. It cannot replace MOSFETs in synchronous rectification, which requires gate drive timing and active control. However, it serves as a drop-in replacement for standard diodes in quasi-resonant or fixed-frequency topologies where synchronous FETs are impractical or cost-prohibitive.
