Product details

Overview

MUR360SB from Taiwan Semiconductor is a 3A, 600V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 50 ns reverse recovery time, 1.25 V max forward voltage at 3 A/25°C, and 75 A surge current capability - deployed in high-efficiency SMPS front-end rectification stages.

For engineers reviewing the MUR360SB datasheet, MUR360SB pinout, MUR360SB application, or MUR360SB equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (R_θJL = 11 °C/W), junction temperature range (–55 to +175 °C), and RoHS/halogen-free compliance for industrial power adapter designs.

Technical Context

This single-die, unidirectional fast recovery rectifier uses glass-passivated junction technology to achieve low leakage (<250 µA at 150°C) and stable switching performance across –55°C to +175°C operating range. Its 38 pF junction capacitance and 50 ns trr support high-frequency operation in 50–500 kHz SMPS topologies.

The device is optimized for automated SMT placement with J-STD-020 Level 1 moisture sensitivity, matte tin-plated leads compliant with J-STD-002, and UL 94V-0 molded compound - enabling reliable reflow soldering without preconditioning.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	Same 3 A / 600 V rating; slightly higher V_F (1.30 V max @ 3 A); R_θJA = 65 °C/W vs. 57 °C/W	Higher thermal resistance requires larger copper area for equivalent cooling	Prefer MUR360SB where board space or thermal budget is constrained
ES3D	Lower I_F (3 A same), but only 200 V V_RRM; t_rr = 35 ns, V_F = 1.15 V max - not voltage-compatible	Restricted to low-line (<120 VAC) or DC-DC output stages	Not suitable as direct replacement; use only in 200 V-class designs

Compared with STTH3L06S and ES3D, the MUR360SB delivers superior thermal performance (R_θJL = 11 °C/W) and full 600 V rating in a widely supported SMB footprint - making it optimal for universal-input, high-density AC-DC conversion where leakage, recovery speed, and manufacturability are jointly critical.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the MUR360SB?

The MUR360SB has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, confirmed in the Absolute Maximum Ratings table for this exact part number. This rating enables safe operation in universal-input (85–265 VAC) SMPS designs where peak line voltage reaches ~375 VDC, providing robust margin against transients and ripple. The MUR360SB datasheet explicitly lists 600 V under the MUR360SB column - distinct from the 400 V rating of the MUR340SB variant.

Does the MUR360SB have a specified reverse recovery time (t_rr)?

Yes, the MUR360SB specifies a maximum reverse recovery time (t_rr) of 50 ns under test conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is published in the Electrical Specifications table and applies directly to the MUR360SB - supporting high-frequency switching in flyback and resonant converters while minimizing switching loss and EMI.

What is the forward voltage (V_F) of the MUR360SB at 3 A and 25°C?

The MUR360SB exhibits a maximum forward voltage (V_F) of 1.25 V at 3 A and 25°C, per the Electrical Specifications table. This parameter is measured under pulsed conditions (PW = 0.3 ms) and defines conduction loss ceiling in continuous operation. At elevated junction temperatures (e.g., 150°C), V_F drops to 1.05 V max, improving efficiency in thermally stressed environments.

Is the MUR360SB RoHS and halogen-free compliant?

Yes, the MUR360SB is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the official datasheet. These compliance attributes are verified for the MUR360SB and apply to its DO-214AA (SMB) package construction, including the UL 94V-0 molding compound and matte tin-plated leads - meeting regulatory requirements for consumer electronics sold in EU, China, and other regulated markets.

What is the junction-to-lead thermal resistance (R_θJL) of the MUR360SB?

The MUR360SB has a typical junction-to-lead thermal resistance (R_θJL) of 11 °C/W, as documented in the Thermal Performance table. This low value reflects efficient heat transfer from die to soldered lead, enabling effective passive cooling when mounted on a 10 mm × 10 mm copper pad - a key advantage over alternatives with higher R_θJL, such as the STTH3L06S (13 °C/W).
