Product details

Overview

STTH200W03TV1 from STMicroelectronics is a 300 V, 200 A ultrafast recovery rectifier diode in a TO-247AD package with 50 ns reverse recovery time (trr), 1.85 V forward voltage (VF) at 100 A, and junction-to-case thermal resistance of 0.25 °C/W. It serves as a main output rectifier in high-power industrial SMPS, UPS, and welding equipment where low conduction loss and fast switching are critical.

For engineers reviewing the STTH200W03TV1 datasheet, STTH200W03TV1 pinout, STTH200W03TV1 application, or STTH200W03TV1 equivalent, key selection criteria include peak repetitive reverse voltage (VRRM), average forward current (IF(AV)), reverse recovery charge (Qrr = 3.2 µC), softness factor (SF = 1.2), and thermal performance under forced-air or heatsink-cooled operation.

Technical Context

This device employs an optimized platinum-doped silicon epitaxial structure to achieve ultrafast recovery with soft reverse recovery characteristics-minimizing EMI and voltage overshoot during turn-off. Its low Qrr and controlled SF reduce snubber stress and gate driver loading in hard-switched topologies.

The diode is designed for unidirectional conduction in high-current DC-link and secondary-side rectification stages. It operates with junction temperatures up to 175 °C and supports repetitive surge currents (IFSM) up to 1200 A (half-sine, 10 ms), making it suitable for transient-heavy industrial power conversion.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	300 V - Maximum allowable repetitive reverse voltage without breakdown; sets system-level DC bus rating limit.
I_F(AV)	200 A - Average forward current at T_C = 110 °C; defines continuous conduction capability with proper heatsinking.
t_rr	50 ns - Measured at I_F = 100 A, dI/dt = 200 A/µs; enables operation in 100–300 kHz SMPS without excessive switching loss.
V_F	1.85 V @ I_F = 100 A - Forward voltage drop determines conduction loss and thermal load at rated current.
Q_rr	3.2 µC - Reverse recovery charge directly impacts turn-off losses and snubber sizing in hard-switched converters.
SF	1.2 - Softness factor quantifies reverse recovery waveform smoothness; higher values reduce voltage ringing and EMI.
R_th(j-c)	0.25 °C/W - Junction-to-case thermal resistance; used with heatsink R_th(c-s) to calculate max T_j under load.

Pinout & Package

TO-247AD package: isolated tab (cathode), single-pin anode lead, standard through-hole mounting with screw-down heatsink interface. Thermal path optimized via direct metal-to-heatsink contact.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead)	Current entry point during forward conduction	Connected to lower-potential side (e.g., transformer secondary center-tap or LLC resonant node).
Cathode (Tab)	Current exit point; electrically connected to metal tab	Must be mounted to heatsink with insulated washer if heatsink is grounded; defines primary thermal path.

Key Features

Feature	Design Value
Ultrafast recovery	50 ns t_rr enables efficient operation in high-frequency SMPS without added snubbers.
Soft recovery characteristic	SF = 1.2 minimizes voltage overshoot and EMI generation during diode turn-off.
High surge capability	1200 A I_FSM (10 ms) supports short-term overloads in welder and UPS inverter stages.
High junction temperature rating	175 °C T_j(max) allows reliable operation in compact, thermally constrained enclosures.
Low Q_rr	3.2 µC reduces turn-off losses by >30% vs. standard fast recovery diodes at same current.

Applications

Industrial Uninterruptible Power Supplies (UPS)

High-Frequency Welding Inverters

IC Role / Device Role / Timing Role: High-current freewheeling and output rectification in dual-active-bridge or phase-shifted full-bridge topologies.

Use Value: 50 ns t_rr and soft recovery suppress voltage spikes across IGBTs, reducing snubber size and failure risk.

Telecom Rectifier Modules

Motor Drive DC-Link Snubbing

Use Scenario: +48 V output stage in 3 kW telecom rectifiers operating at 200 kHz with forced-air cooling.

IC Role / Device Role / Timing Role: Synchronous rectifier replacement in high-efficiency AC/DC front-ends where SiC cost is prohibitive.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MBR20030CT	30 V lower V_RRM (270 V), identical I_F(AV), slightly higher V_F (1.95 V @ 100 A)	Limited to ≤400 V DC bus systems; less margin for line transients	Select when cost sensitivity outweighs 30 V derating need and thermal design accommodates higher V_F.
Vishay VS-200EWH03	Same V_RRM/I_F(AV), but slower t_rr (75 ns) and higher Q_rr (4.8 µC)	Higher switching loss in >150 kHz designs; requires larger snubber	Prefer for lower-frequency (<100 kHz), cost-driven applications where EMI filtering is already robust.

Compared with MBR20030CT and VS-200EWH03, STTH200W03TV1 offers superior high-frequency efficiency due to its 50 ns t_rr and 3.2 µC Q_rr, tighter thermal resistance (0.25 vs. 0.30–0.35 °C/W), and broader safe operating area at 175 °C junction temperature.

FAQ

What is the maximum allowable case temperature for continuous operation?

The STTH200W03TV1 is rated for continuous operation with case temperature (T_C) up to 110 °C, as specified in the absolute maximum ratings table. At this temperature, the device delivers its full 200 A average forward current rating when mounted on a heatsink with appropriate thermal interface material and sufficient surface area. Exceeding 110 °C case temperature risks exceeding the 175 °C maximum junction temperature, especially under high dI/dt conditions.

Is the TO-247AD package electrically isolated?

No-the TO-247AD package used for STTH200W03TV1 has an electrically connected metal tab serving as the cathode terminal. The tab is not internally insulated from the semiconductor die. When mounting to a heatsink, electrical isolation must be ensured using a mica or ceramic washer and isolated mounting hardware if the heatsink is grounded or at a different potential.

Can STTH200W03TV1 replace a 600 V diode in a 400 V DC bus?

No-STTH200W03TV1 has a 300 V peak repetitive reverse voltage (V_RRM) rating. In a 400 V DC bus, transient overvoltages (e.g., from line surges or inductive kickback) can easily exceed 300 V, risking avalanche breakdown and catastrophic failure. A minimum 2× derating ratio is recommended, so a 600 V or higher V_RRM diode is required for reliable operation in that system.

Does this diode require a gate resistor or external drive circuitry?

No-STTH200W03TV1 is a passive two-terminal power diode with no gate or control terminal. It conducts automatically when forward-biased and blocks when reverse-biased. Unlike MOSFETs or IGBTs, it requires no gate drive, biasing, or timing control circuitry. Its behavior is governed solely by applied voltage polarity and magnitude relative to its V_F and V_RRM ratings.
