Product details

Overview

STPS20H100CG from STMicroelectronics is a dual-center-tap 100 V, 20 A Schottky rectifier in D²PAK (TO-263) package, optimized for high-frequency switch-mode power supplies. It delivers typ. 0.59 V forward voltage at 10 A/125 °C, supports 175 °C max junction temperature, and features avalanche rating and insulated packaging - used in notebook adapters and on-board DC/DC converters.

For engineers reviewing the STPS20H100CG datasheet, STPS20H100CG pinout, STPS20H100CG application, or STPS20H100CG equivalent, key selection criteria include low conduction loss (VF), thermal robustness (Rth(j-c) = 1.6 °C/W per diode), dual-diode center-tap topology, and ECOPACK®2 compliance for surface-mount power conversion designs.

Technical Context

This dual Schottky rectifier integrates two anti-parallel diodes sharing a common cathode terminal, enabling center-tap transformer secondary rectification. Its low VF–IR trade-off minimizes conduction and leakage losses simultaneously across –65 to +175 °C operating range.

The device uses platinum-doped silicon for stable high-temperature operation and is rated for 250 A non-repetitive surge current (10 ms sine). Thermal design relies on case-to-heatsink conduction, with Rth(j-c) = 1.6 °C/W per diode in D²PAK, and insulating capability of 2000 VRMS (in TO-220FPAB variant).

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	100 V - Maximum reverse blocking voltage per diode; defines safe DC/peak AC input voltage limit in SMPS secondary side.
IF(AV)	10 A per diode / 20 A total - Average forward current rating at TC = 160 °C; sets continuous output current capability in dual-phase rectifier layout.
VF (typ)	0.59 V @ 10 A, 125 °C - Low forward drop reduces conduction loss by ~30% vs. standard Si diodes; critical for >90% efficiency in 12–19 V adapter outputs.
Tj (max)	+175 °C - Enables operation in thermally constrained environments (e.g., sealed LED drivers or compact DC/DC modules) without derating below 150 °C ambient.
Rth(j-c)	1.6 °C/W per diode - Junction-to-case thermal resistance in D²PAK; allows direct heatsink mounting for <10 W per diode dissipation at ΔT ≤ 16 °C.
IR (max)	6 mA @ 125 °C, VRRM - Low leakage preserves standby efficiency in energy-sensitive applications like EU CoC Tier 2-compliant adapters.
PARM	775 W @ 10 µs, Tj = 125 °C - Avalanche pulse power rating ensures survivability during transient overvoltage events (e.g., transformer flyback spikes).

Pinout & Package

D²PAK (TO-263) package: surface-mount, isolated tab, single-row 3-pin outline with exposed copper drain pad for thermal conduction. Mechanical dimensions per DS1216 Rev 10: D = 8.60–9.35 mm, E = 10.00–10.55 mm, L = 1.90–2.79 mm, e = 2.54 mm pitch.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Anode 1)	First diode anode	Connects to transformer secondary winding end #1; enables half-wave rectification path in center-tap topology.
Pin 2 (Cathode)	Common cathode	Shared output node for both diodes; ties to +VOUT rail and bulk capacitor; requires low-inductance PCB pour.
Pin 3 (Anode 2)	Second diode anode	Connects to transformer secondary winding end #2; alternates conduction with Anode 1 to deliver full-wave output.

Key Features

Feature	Design Value
Negligible switching losses	Zero reverse recovery charge (Qrr ≈ 0); eliminates switching tail current and associated EMI in >100 kHz SMPS designs.
Avalanche rated	775 W repetitive peak avalanche power (10 µs pulse); sustains voltage overshoot without failure during transformer reset transients.
Insulated package option	TO-220FPAB variant provides 2000 VRMS isolation; STPS20H100CG (D²PAK) lacks internal insulation but enables automated assembly and lower profile.
ECOPACK®2 compliant	Meets RoHS, halogen-free, and lead-free reflow requirements; qualified for industrial and consumer-grade production with Pb-free solder compatibility.
High junction temperature capability	Rated to +175 °C Tj; supports operation in enclosed LED drivers or automotive cabin modules where ambient exceeds 105 °C.

Applications

Notebook Adapter

On-board DC/DC Converter

Use Scenario: 19 V/3.42 A output stage in ultra-thin laptop AC/DC adapter with <15 mm height constraint.

IC Role / Device Role / Timing Role: Dual-center-tap Schottky rectifier replacing two discrete diodes; synchronizes with 200 kHz flyback controller secondary timing.

Use Value: 0.59 V VF at 125 °C reduces conduction loss by 1.8 W vs. legacy Si diodes, enabling passive cooling and CoC Tier 2 compliance.

Use Scenario: 12 V → 3.3 V/15 A point-of-load converter on server motherboard with tight thermal budget.

IC Role / Device Role / Timing Role: Center-tap synchronous rectification element; conducts during alternate half-cycles of transformer secondary waveform.

Use Value: 1.6 °C/W Rth(j-c) enables direct copper pour heatsinking, limiting ΔTj to 12 °C at 10 A per diode - avoids fan dependency.

LED Lighting Driver

Game Console Power Supply

Use Scenario: Constant-current LED driver for commercial downlights with 36 V output and 700 mA load.

IC Role / Device Role / Timing Role: Output rectifier in quasi-resonant flyback; handles 100 kHz switching with minimal reverse recovery noise.

Use Value: 6 mA IR max at 125 °C prevents standby power drift in thermally coupled LED + driver enclosure, maintaining <0.5 W no-load consumption.

Use Scenario: 12 V auxiliary rail in gaming console PSU delivering 20 A to GPU VRM with <50 mV ripple spec.

IC Role / Device Role / Timing Role: Dual-path rectifier feeding parallel bulk capacitors; shares current between two anodes under dynamic load steps.

Use Value: 250 A IFSM rating withstands 20 A × 2.5× transient surges during GPU boost mode, eliminating need for external crowbar protection.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-20CPH05	50 V VRRM, 20 A IF(AV), TO-247AC package, Rth(j-c) = 1.0 °C/W - higher thermal performance but lower voltage rating.	Restricted to ≤50 V outputs (e.g., 5 V/12 V rails); unsuitable for 19 V notebook adapters or 36 V LED drivers.	Select only when system VRRM < 60 V and thermal margin is critical; requires through-hole assembly and larger board area.
ON Semiconductor MBR20100CT	100 V VRRM, 20 A IF(AV), TO-220 package, VF = 0.85 V @ 10 A/25 °C - higher forward drop, no avalanche rating.	Lacks PARM specification and thermal robustness above 150 °C; not recommended for sealed or high-ambient environments.	Acceptable for cost-sensitive, low-power (<10 A) applications with active cooling; avoid in thermally constrained or high-reliability designs.

Compared with VS-20CPH05 and MBR20100CT, STPS20H100CG uniquely balances 100 V blocking, 0.59 V low-VF operation at elevated temperature, avalanche ruggedness, and D²PAK surface-mount scalability - making it optimal for space-constrained, high-efficiency 12–36 V SMPS outputs.

FAQ

What is the maximum continuous forward current per diode for STPS20H100CG at 160 °C case temperature?

The datasheet specifies IF(AV) = 10 A per diode at TC = 160 °C for D²PAK, I²PAK, and TO-220AB packages. This rating assumes δ = 0.5 square-wave conduction and accounts for thermal derating; exceeding this requires forced cooling or reduced duty cycle.

Does STPS20H100CG have integrated thermal protection or shutdown circuitry?

No. STPS20H100CG is a passive Schottky rectifier with no internal control logic or thermal shutdown. System-level protection must be implemented externally via temperature sensors, current limiting, or controller-based overtemperature flags.

Can STPS20H100CG be used in place of a single-anode Schottky diode in a bridge configuration?

No. Its dual-center-tap structure (A1–K–A2) is incompatible with full-bridge or single-diode layouts. Substitution would require rewiring the transformer secondary and redesigning the output filter; use STTH2003 or similar single-diode parts instead.

Is the D²PAK package of STPS20H100CG electrically insulated from the cathode terminal?

No. The D²PAK package has a conductive copper tab electrically connected to the cathode (Pin 2). For isolation, ST offers the TO-220FPAB variant (STPS20H100CFP) with 2000 VRMS insulation; D²PAK requires insulated mounting hardware if chassis grounding is needed.
