Diodes Incorporated MURB1610CT-T-F

Overview

MURB1610CT-T-F from Diodes Incorporated is a 16A, 100V surface-mount super-fast rectifier diode in D2PAK (TO-263) package with glass-passivated diffused junction, 25ns recovery time, 0.975V forward voltage at 8A, and 5μA reverse leakage at 25°C - used in high-frequency AC/DC converters and switch-mode power supplies.

For engineers reviewing the MURB1610CT-T-F datasheet, MURB1610CT-T-F pinout, MURB1610CT-T-F application, or MURB1610CT-T-F equivalent, key selection criteria include peak repetitive reverse voltage (100V), average rectified current (16A @ TC=125°C), thermal resistance (1.5°C/W), fast recovery time (25ns), and low forward voltage drop for efficiency-critical secondary-side rectification.

Technical Context

This dual common-cathode ultrafast rectifier integrates two independent 100V/16A diode elements in a single D2PAK thermally optimized package. Its diffused junction and glass passivation ensure stable operation up to 150°C junction temperature and robust surge tolerance (100A peak, 8.3ms).

The device targets high-frequency switching topologies where low trr minimizes switching losses and low VFM reduces conduction losses. Junction capacitance is specified at 85pF (1MHz, 4V reverse bias), supporting predictable snubber design in flyback and LLC resonant converters.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast rectifier applications.

Compared with MURB1610CT-T-F, STTH1602CW offers higher voltage headroom but sacrifices board space and thermal coupling efficiency, while IXYS MUR1620CT matches the D2PAK form factor but trades 5ns of recovery speed for 100V extra blocking - making the Diodes part optimal for 100V, high-frequency, space-constrained designs.

FAQ

What is the maximum allowable case temperature for continuous operation?

The MURB1610CT-T-F is rated for continuous operation with case temperature up to 125°C, delivering its full 16A average forward current. Exceeding this temperature requires linear derating per Figure 1 in the datasheet - at 150°C case, the current rating drops to approximately 12A. Thermal design must maintain TC ≤125°C using ≥5.0 mm² copper pad per diode element.

Can this device be used in a full-bridge rectifier configuration?

Yes - the dual common-cathode structure supports full-bridge use by connecting Pins 1 and 3 to AC inputs and the common cathode (Pins 2 & 4) to the positive DC rail. However, it is not internally configured as a bridge; external diodes are needed for the negative rail. For integrated bridges, consider Diodes' GBPC series.

Is the D2PAK package lead-free and RoHS compliant?

Yes, the MURB1610CT-T-F is manufactured with lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "-T-F" suffix explicitly denotes lead-free, halogen-free, and RoHS-compliant packaging per Diodes Incorporated's product marking standard.

How does the 25ns recovery time impact EMI in high-frequency designs?

A 25ns trr minimizes reverse recovery current overshoot and associated dI/dt-induced radiated emissions. When paired with proper snubbing and layout (short traces, ground plane separation), it enables clean switching waveforms in 300–500 kHz converters - reducing filter component count and improving conducted EMI margins versus 50+ ns rectifiers.
