Product details

Overview

MURF880G from Taiwan Semiconductor is an ultra-fast recovery rectifier diode in ITO-220AC package, rated for 8 A average forward current and 800 V repetitive peak reverse voltage, with 25 ns reverse recovery time and 1.69 V typical forward voltage at 4 A/25°C - used in high-frequency DC-DC converters and switching inverters.

For engineers reviewing the MURF880G datasheet, MURF880G pinout, MURF880G application, or MURF880G equivalent, key selection criteria include reverse recovery time (trr ≤ 25 ns), thermal resistance (R_θJL = 7 °C/W), junction temperature range (–55 to +175 °C), and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

The MURF880G employs a single-die silicon planar epitaxial structure optimized for ultra-fast soft recovery, minimizing switching losses in hard-switched topologies. Its 25 ns trr and low Q_rr support operation up to several hundred kHz in SMPS designs.

Thermally, it features a low R_θJL of 7 °C/W when mounted on a 4"×6"×0.25" aluminum heatsink, enabling sustained 8 A conduction at T_J ≤ 175 °C. The ITO-220AC case provides direct metal tab thermal path and matte tin-plated leads compliant with J-STD-002 solderability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - supports input stages in 400 V AC rectification or 600 V bus applications without derating
I_F	8 A - continuous average forward current rating at T_C = 110 °C with heatsink
I_FSM	100 A - withstands 8.3 ms half-sine surge, suitable for inrush-limited PFC and motor drive freewheeling
t_rr	25 ns - enables high-frequency switching (>200 kHz) with reduced EMI and diode switching loss
V_F @ 8 A / 25°C	2.00–2.30 V - defines conduction loss baseline; lower at elevated T_J improves thermal stability
R_θJL	7 °C/W - allows direct thermal coupling to heatsink via insulated tab, critical for compact power stage layout
I_R @ 800 V / 150°C	≤ 200 µA - ensures minimal leakage in high-temp industrial environments

Pinout & Package

Package: ITO-220AC - insulated TO-220 variant with electrically isolated metal tab (rated ≥ 2500 V RMS isolation), matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on device body.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH8R06DJF	600 V V_RRM, 20 ns t_rr, TO-220AC package, non-isolated tab	Better speed but lower voltage rating; requires redesign for 800 V systems	Select when system V_RRM margin allows 600 V and lowest possible t_rr is critical

FAQ

What is the maximum junction temperature rating for the MURF880G?

The MURF880G has a maximum junction temperature (T_J) rating of +175 °C, verified per absolute maximum ratings table in the official datasheet. This allows reliable operation in sealed industrial enclosures or high-ambient environments. Derating curves confirm 8 A I_F is sustainable at T_C = 110 °C with proper heatsinking. The MURF880G must not exceed this limit during steady-state or transient conditions to maintain long-term reliability.

Does the MURF880G have an electrically isolated tab?

Yes, the MURF880G uses the ITO-220AC package, which features an electrically isolated metal tab rated for ≥2500 V RMS isolation between tab and leads. This eliminates the need for insulating washers when mounting to a common heatsink, simplifying thermal design and reducing assembly cost. The isolation is validated per JEDEC standards and confirmed in the mechanical data section of the MURF880G datasheet.

What is the reverse recovery time (t_rr) specification for the MURF880G?

The MURF880G has a maximum reverse recovery time (t_rr) of 25 ns, measured under specified test conditions: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A. This value is guaranteed across temperature and ensures minimal switching loss in high-frequency converters. The MURF880G datasheet lists no typical value - only the 25 ns max - making it suitable for designs targeting <300 kHz operation with tight EMI control.

Is the MURF880G RoHS and halogen-free compliant?

Yes, the MURF880G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the matte tin-plated leads satisfy J-STD-002 solderability requirements. These compliance statements are explicitly declared in the "Features" and "Mechanical Data" sections of the official MURF880G datasheet revision C2105.

What is the thermal resistance from junction to lead (R_θJL) for the MURF880G?

The MURF880G has a typical junction-to-lead thermal resistance (R_θJL) of 7 °C/W, measured with the device mounted on a 4"×6"×0.25" aluminum heatsink. This value reflects direct conduction through the isolated tab and is critical for estimating die temperature under load. The MURF880G datasheet specifies R_θJL separately from R_θJC (8 °C/W) and R_θJA (13 °C/W), confirming its suitability for thermally constrained layouts.
