Product details

Overview

FFP30UP20DNTU from Fairchild Semiconductor is an ultrafast recovery power rectifier in TO-220 package, rated for 200 V peak repetitive reverse voltage (V_RRM), 15 A average forward current (I_F(AV)), and 45 ns reverse recovery time (t_rr) at I_F = 15 A. It serves as a primary output rectifier in high-frequency switching power supplies.

For engineers reviewing the FFP30UP20DNTU datasheet, pinout, applications, or equivalent options, key selection criteria include soft-recovery behavior, avalanche energy rating (20 mJ), thermal resistance (2.2 °C/W), and dual-anode configuration for center-tap transformer designs.

Technical Context

This device employs planar construction to ensure stable junction temperature operation up to +150 °C and supports non-repetitive surge currents up to 150 A (60 Hz half-sine). Its soft recovery characteristic minimizes EMI in high-di/dt circuits, with t_rr specified at 35 ns (I_F = 1 A) and 45 ns (I_F = 15 A).

The dual-anode, single-cathode topology (pins 1–Anode, 2–Cathode, 3–Anode) enables use in center-tapped full-wave rectification without external parallel diodes. Junction-to-case thermal resistance of 2.2 °C/W supports direct heatsink mounting in industrial SMPS and motor freewheeling applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Withstands repetitive reverse voltage up to 200 V without breakdown in SMPS output stages.
I_F(AV)	15 A @ T_C = 120 °C - Sustains continuous forward conduction at 15 A when case temperature is held at 120 °C.
t_rr	45 ns @ I_F = 15 A - Ultrafast soft recovery reduces switching losses and voltage overshoot in 100–500 kHz converters.
W_AVL	20 mJ - Rated avalanche energy allows safe operation during inductive load turn-off transients (e.g., motor freewheeling).
R_θJC	2.2 °C/W - Enables efficient thermal transfer to heatsink; 15 A conduction yields ~33 °C junction rise above case at steady state.
V_FM	1.15 V @ I_F = 15 A, T_C = 25 °C - Forward voltage drop directly impacts conduction loss and thermal design margin.

Pinout & Package

FFP30UP20DNTU uses a standard TO-220 package with isolated tab (non-conductive backside), 50-unit tape-and-reel packaging, and mechanical dimensions compliant with JEDEC TO-220AB outline.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode	First anode terminal; connects to one leg of center-tapped transformer secondary or positive rail in dual-anode configuration.
2	Cathode	Common cathode node; output node for full-wave rectified DC in center-tap topologies.
3	Anode	Second anode terminal; connects to opposite leg of center-tapped transformer secondary.

Key Features

Feature	Design Value
Ultrafast soft recovery	35–45 ns t_rr with low reverse recovery current (I_rr ≤ 12 A), reducing EMI and snubber stress in high-frequency SMPS.
Avalanche energy rating	20 mJ capability enables robustness against inductive switching transients without external clamping in motor drive freewheel paths.
Dual-anode, single-cathode topology	Eliminates need for two discrete diodes in center-tapped rectifiers-reduces PCB area, thermal mismatch, and assembly cost.
Planar junction construction	Ensures stable parameter distribution across temperature and long-term reliability under repeated thermal cycling in industrial power systems.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH30L06D	600 V V_RRM, 30 A I_F(AV), 60 ns t_rr, TO-220AC package (single-anode)	Higher voltage rating but slower recovery and no dual-anode topology	Select when >200 V blocking is required and center-tap configuration is not used.
IXYS MUR3020CT	200 V V_RRM, 30 A I_F(AV), 60 ns t_rr, TO-220AB dual-common-cathode	Dual-cathode instead of dual-anode; different pinout (1–Cathode, 2–Anode, 3–Cathode)	Use only if circuit topology accommodates common-cathode arrangement and board layout allows pinout rework.

Compared with STTH30L06D and IXYS MUR3020CT, the FFP30UP20DNTU uniquely provides dual-anode topology with 45 ns recovery and 20 mJ avalanche rating in a TO-220 footprint-making it optimal for compact center-tapped SMPS and motor freewheeling where layout symmetry and transient robustness are critical.

FAQ

What is the pin configuration of the FFP30UP20DNTU?

The FFP30UP20DNTU has a three-pin TO-220 package with pin 1 = Anode, pin 2 = Cathode, and pin 3 = Anode. This dual-anode, single-cathode arrangement is optimized for center-tapped transformer full-wave rectification. The tab is electrically isolated, allowing direct heatsink mounting without insulation hardware.

Does the FFP30UP20DNTU support avalanche operation?

Yes, the FFP30UP20DNTU is explicitly rated for avalanche energy: 20 mJ under specified test conditions (L = 40 mH). This rating permits controlled, non-destructive operation during inductive switching events-critical for motor freewheeling and snubber applications where voltage transients exceed V_RRM.

What is the maximum junction temperature for the FFP30UP20DNTU?

The FFP30UP20DNTU has a specified operating junction temperature range of –65 °C to +150 °C. At I_F(AV) = 15 A and T_C = 120 °C, the junction temperature remains within this limit assuming proper heatsinking and the stated R_θJC of 2.2 °C/W.

How does the soft recovery characteristic benefit EMI performance in SMPS designs?

The soft recovery of the FFP30UP20DNTU-evidenced by low reverse recovery current (I_rr ≤ 12 A) and controlled fall time-reduces high-frequency ringing and dv/dt-induced noise coupling. In practice, this lowers conducted EMI in 100–500 kHz SMPS, easing compliance with CISPR 22/32 Class B limits without oversized input filters.

Is the FFP30UP20DNTU compatible with lead-free reflow soldering processes?

Yes, the FFP30UP20DNTU is qualified for lead-free reflow soldering per J-STD-020. Its TO-220 package and internal construction meet peak temperature requirements up to 260 °C for 10 seconds. The device marking "F30UP20DN" on the package confirms RoHS-compliant material content per original Fairchild documentation.
