Product details

Overview

SDT20A100CTFP from Diodes Incorporated is a 20A dual common-cathode Trench Schottky rectifier in ITO-220AB package, rated for 100V peak reverse voltage, with max 0.67V forward voltage at 10A/25°C and 100µA reverse leakage at 100V/25°C. It serves as a high-efficiency output rectifier or freewheel diode in DC-DC converters and AC-DC adapters operating under high-temperature conditions.

For engineers reviewing the SDT20A100CTFP datasheet, SDT20A100CTFP pinout, SDT20A100CTFP application, or SDT20A100CTFP equivalent, key selection criteria include its low VF stability up to +125°C, soft fast switching behavior, 4°C/W junction-to-case thermal resistance (ITO-220AB), and AEC-Q101 readiness for automotive power systems.

Technical Context

This dual-leg Schottky rectifier integrates two independent 10A-rated anode terminals sharing a single cathode terminal, enabling synchronous or interleaved rectification topologies. Its trench MOS structure delivers lower forward voltage and superior high-temperature IR stability versus planar Schottky devices.

The device operates within -55°C to +150°C junction temperature range and supports non-repetitive surge currents up to 200A (8.3ms half-sine). Thermal performance is validated with a 50mm×50mm×23mm aluminum heatsink, yielding 4°C/W R_θJC in ITO-220AB configuration.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse blocking voltage per leg; defines safe DC or peak AC voltage handling in rectifier applications.
I_O (per leg)	10 A - Continuous average forward current rating per anode-cathode path at 25°C ambient; total device rating is 20A dual-leg sum.
V_F max	0.67 V @ 10A, 25°C - Ensures low conduction loss in high-current DC-DC outputs; drops to 0.63V at 125°C for stable efficiency across temperature.
I_R max	100 µA @ 100V, 25°C - Low leakage preserves efficiency in standby modes; rises to only 20 µA at 125°C, confirming thermal robustness.
R_θJC	4 °C/W - Junction-to-case thermal resistance in ITO-220AB package; enables direct heatsink mounting for high-power density designs.
I_FSM	200 A - Non-repetitive surge current capability supports inrush and transient load events without degradation.

Pinout & Package

Package: ITO-220AB (Type HE) - Insulated through-hole plastic package with integral heatsink tab, UL 94V-0 rated, matte tin-plated copper leadframe, 1.69g weight.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (Lead 1)	Input terminal for first rectifier leg	Accepts AC or switched input; electrically isolated from case; used in dual-phase or redundancy configurations.
Cathode (Lead 2 / Tab)	Common output node for both legs	Internally bonded to metal tab; must be electrically connected to system ground or output rail; primary thermal path to heatsink.
Anode 2 (Lead 3)	Input terminal for second rectifier leg	Independent anode path enabling dual-output or interleaved operation; pin 3 is isolated from tab and pin 1.

Key Features

Feature	Design Value
Low forward voltage drop	0.67 V max @ 10A/25°C reduces conduction losses by >15% vs. standard silicon rectifiers in 12V–48V DC-DC outputs.
Soft, fast switching capability	Negligible reverse recovery charge (Q_rr) eliminates switching spikes and EMI in high-frequency SMPS (>300 kHz).
High-temperature leakage stability	IR = 20 µA @ 100V/125°C ensures minimal standby power loss in automotive under-hood environments.
Halogen- and antimony-free "Green" construction	<900 ppm Br, <900 ppm Cl, <1000 ppm Sb meets global environmental compliance mandates without performance trade-offs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual common-cathode Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-20CPH05-M3	50V V_RRM, 20A total, TO-247AC package, R_θJC = 1.6°C/W, VF = 0.52V @ 10A/25°C	Lower voltage rating limits use to ≤24V systems; higher thermal conductivity suits higher ambient but requires larger footprint.	Select when 50V blocking suffices and board space allows TO-247; avoid in 48V+ or automotive 12V starter-load scenarios.
ON Semiconductor MBR20100CT	100V V_RRM, 20A total, TO-220AB package, R_θJC = 2°C/W, VF = 0.75V @ 10A/25°C, IR = 500µA @ 100V/25°C	Higher VF increases conduction loss; higher IR degrades high-temp standby efficiency; lower thermal resistance benefits low-airflow designs.	Prefer where cost sensitivity outweighs thermal or leakage requirements; verify IR impact in always-on automotive modules.

Compared with VS-20CPH05-M3 and MBR20100CT, SDT20A100CTFP uniquely balances 100V rating, ultra-low 0.67V VF, sub-100µA leakage at 125°C, and ITO-220AB's insulated thermal path-making it optimal for thermally constrained, high-reliability 48V automotive and server power stages.

FAQ

Is SDT20A100CTFP qualified to AEC-Q101?

Yes, SDT20A100CTFP is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified on Diodes' public AEC-Q101 list, it meets all stress test requirements per AEC-Q101 Rev D and is designated for automotive applications requiring change control-qualification status can be confirmed via Diodes' automotive support team.

What is the difference between SDT20A100CT and SDT20A100CTFP?

SDT20A100CT uses TO-220AB (generic) with R_θJC = 2°C/W and uninsulated tab, while SDT20A100CTFP uses ITO-220AB (Type HE) with insulated tab, R_θJC = 4°C/W, and tighter dimensional tolerances. The FP variant enables direct heatsink mounting without electrical isolation hardware in safety-critical systems.

Can SDT20A100CTFP be used in parallel configurations?

Yes-its matched dual-leg structure and positive temperature coefficient of V_F enable natural current sharing. Derating to 8A per leg is recommended for parallel operation at >85°C ambient; ensure symmetrical PCB layout and thermal coupling to maintain balance within ±10% current distribution.

Does SDT20A100CTFP require a heatsink in 10A continuous operation?

Yes-continuous 10A per leg generates ~6.7W dissipation (10A × 0.67V). With R_θJC = 4°C/W and typical R_θCA > 20°C/W for bare ITO-220AB, junction temperature exceeds 150°C without a heatsink. A 50mm×50mm×23mm Al heatsink is specified in the datasheet to maintain safe operation.
