Product details

Overview

MUR1640CT from Taiwan Semiconductor is a dual-die ultra-fast recovery rectifier in TO-220AB package, rated for 16A average forward current and 400V repetitive peak reverse voltage, with 50ns reverse recovery time and 175°C maximum junction temperature-used in high-frequency switching mode power supplies and freewheeling paths.

For engineers reviewing the MUR1640CT datasheet, MUR1640CT pinout, MUR1640CT application, or MUR1640CT equivalent, key selection criteria include its 400V V_RRM, 1.300V forward voltage at 8A/25°C, 2°C/W junction-to-case thermal resistance, AEC-Q101 qualification option (MUR1640CTH), and TO-220AB mechanical compatibility.

Technical Context

The MUR1640CT integrates two independent ultra-fast rectifying dies in a single TO-220AB package with common cathode configuration, enabling dual-channel operation without external paralleling. Its 50ns trr and low Qrr support high-frequency (>100 kHz) DC–DC converters and inverters where switching loss minimization is critical.

Thermally optimized with 2°C/W R_θJC, the device sustains 16A continuous conduction at case temperatures up to 100°C. The glass-passivated junction ensures stable performance across -55°C to +175°C operating range, meeting automotive-grade reliability when ordered as MUR1640CTH.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1604D	Same 16A/400V rating, but 35ns t_rr; R_θJC = 2.5°C/W; TO-220AC package (single-diode).	Requires two devices for dual-anode function; slightly faster but thermally less efficient.	Select when lowest possible recovery time is prioritized over thermal density and dual-diode integration.
IXYS MUR1640CT	Identical electrical specs and TO-220AB dual-common-cathode pinout; same 50ns t_rr, 1.300V V_F, 2°C/W R_θJC.	Drop-in replacement with identical footprint, thermal interface, and circuit role-no layout change needed.	Preferred for supply chain diversification while maintaining full functional and mechanical equivalence.

Compared with STTH1604D and IXYS MUR1640CT, the Taiwan Semiconductor MUR1640CT offers integrated dual-diode functionality in TO-220AB with best-in-class thermal resistance (2°C/W), making it optimal for space-constrained, high-power-density designs where board area and thermal management are critical.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the MUR1640CT?

The MUR1640CT has a V_RRM of 400 V, verified per Taiwan Semiconductor's I2104 datasheet. This rating defines the highest reverse voltage the device can block repeatedly without avalanche breakdown. It is specifically assigned to the MUR1640CT variant-distinct from MUR1620CT (200 V) and MUR1660CT (600 V)-and applies to each diode in the dual-die TO-220AB package.

Does the MUR1640CT have AEC-Q101 qualification?

The base MUR1640CT is not AEC-Q101 qualified, but the MUR1640CTH variant is explicitly certified per the ordering information in the datasheet. The "H" suffix denotes AEC-Q101 qualification, including stress testing for temperature cycling, humidity bias, and mechanical shock-making MUR1640CTH suitable for automotive power electronics where MUR1640CT is not approved.

What is the forward voltage (V_F) of the MUR1640CT at 8A and 25°C?

The MUR1640CT exhibits a maximum forward voltage of 1.300 V at I_F = 8 A and T_J = 25°C, as specified in the Electrical Specifications table. This value is measured per diode under pulse conditions (PW = 0.3 ms), and drops to 1.100 V at 150°C junction temperature-critical for thermal modeling and conduction loss calculation in the MUR1640CT's target applications.

How is the pin configuration arranged on the MUR1640CT in TO-220AB package?

The MUR1640CT uses a 3-pin TO-220AB package with common-cathode dual-diode topology: Pin 1 (left lead) is Anode 1, Pin 2 (center lead/tab) is the shared Cathode electrically connected to the metal case, and Pin 3 (right lead) is Anode 2. Polarity is marked on the device body, and the case must be electrically isolated from other circuit nodes unless used as the cathode return path.

What is the junction-to-case thermal resistance (R_θJC) of the MUR1640CT?

The MUR1640CT has a typical junction-to-case thermal resistance of 2°C/W, as confirmed in the Thermal Performance section of the datasheet. This value applies to both MUR1640CT and MUR1660CT variants and is lower than MUR1620CT (3°C/W), reflecting optimized die attachment and thermal path design-enabling higher power dissipation within the same TO-220AB footprint.
