Product details

Overview

STPS15M80CG-TR from STMicroelectronics is a dual common-cathode Schottky rectifier in D2PAK (TO-263) package, rated for 80 V repetitive peak reverse voltage and 2 × 7.5 A average forward current per diode at T_c = 155 °C. It delivers low forward voltage drop (0.565 V typ. @ 7.5 A, 125 °C) and ultra-low leakage (5 µA max @ 125 °C, V_R = V_RRM), enabling high-efficiency secondary-side rectification in compact AC/DC adapters for LCD TVs and gaming consoles.

For engineers reviewing the STPS15M80CG-TR datasheet, STPS15M80CG-TR pinout, STPS15M80CG-TR application, or STPS15M80CG-TR equivalent, this device requires attention to thermal derating in D2PAK layout, avalanche energy handling (5400 W peak, t_p = 1 µs), and dual-diode parallel conduction loss modeling using P = 0.50 × I_F(AV) + 0.0147 × I_F(RMS)².

Technical Context

This dual Schottky rectifier integrates two independent anode terminals (A1, A2) sharing a single cathode (K), enabling synchronous or interleaved secondary-side rectification in flyback and LLC topologies. Its TO-263 (D2PAK) package provides 1.55 °C/W total junction-to-case thermal resistance per device and supports surface-mount assembly with copper pad area optimization per Figure 14.

The device features specified avalanche capability (V_ARM = 100 V, I_AR < 16.2 A, t_p < 1 µs) and operates up to 175 °C junction temperature, with reverse leakage tightly controlled across temperature (25 µA max @ 25 °C, 15 mA max @ 125 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	80 V - Maximum repetitive reverse blocking voltage per diode; defines minimum input-output differential margin in 5 V/12 V output rails.
I_F(AV) per diode	7.5 A @ T_c = 155 °C - Sustained DC current rating per anode; determines heatsink sizing when both diodes conduct simultaneously.
V_F typ.	0.565 V @ 7.5 A, 125 °C - Forward voltage at full load and elevated temperature; directly sets conduction loss (P_cond ≈ I × V_F) in high-frequency SMPS.
I_R max	15 mA @ 125 °C, V_R = V_RRM - Reverse leakage at worst-case operating temperature; impacts standby power and thermal runaway risk in multi-diode arrays.
T_j(max)	175 °C - Absolute maximum junction temperature; enables operation in thermally constrained adapter enclosures without forced airflow.
R_th(j-c) total	1.55 °C/W - Total thermal resistance from junction to case (both diodes); used with PCB copper area to calculate real-world T_j rise.

Pinout & Package

STPS15M80CG-TR uses the D2PAK (TO-263) surface-mount package with exposed metal tab for thermal conduction. The package measures 10.0–10.4 mm × 8.95–9.35 mm × 2.4–3.2 mm (L × W × H), weighs 1.48 g, and is supplied in 1000-piece tape-and-reel format.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode; connects to transformer secondary winding or switching node in dual-output designs.
A2	Anode 2	Input terminal for second independent Schottky diode; enables dual-rail rectification or phase-split current sharing.
K	Common Cathode	Shared output node; ties both diodes to output capacitor and load; must be routed with low-inductance, high-current copper pour.

Key Features

Feature	Design Value
Optimized V_F/I_R trade-off	0.565 V forward drop @ 7.5 A/125 °C with only 15 mA leakage @ same condition-enables >92% efficiency at light-to-full load in 65 kHz+ adapters.
Avalanche-rated structure	5400 W peak avalanche power (t_p = 1 µs) validated per AN1768-absorbs transformer leakage energy without failure during transient overvoltage events.
High-T_j capability	175 °C max junction temperature-permits operation in sealed, fanless enclosures where ambient exceeds 70 °C without derating.
Insulated thermal path	D2PAK tab electrically isolated per JEDEC MO-211; allows direct mounting to heatsink without insulator washer while maintaining 2000 V isolation (per TO-220FPAB variant spec).

Applications

Use Scenario: Dual 12 V/2 A outputs in 240 W integrated LCD TV power supply.

IC Role / Device Role / Timing Role: Common-cathode dual rectifier delivering independent +12VA and +12VB rails from split secondary winding.

Use Value: Eliminates cross-conduction risk between rails and reduces BOM count by one component versus discrete solution.

Gaming Console AC/DC Adapter

Notebook Charger Output Stage

Use Scenario: 12 V/8 A output in compact 100 W adapter with high-density layout and no forced cooling.

IC Role / Device Role / Timing Role: Primary secondary-side rectifier handling full load current; leverages D2PAK thermal performance for passive dissipation.

Use Value: Maintains T_j < 145 °C at full load with 4 cm² 2-oz copper, avoiding thermal shutdown during sustained gaming sessions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-15CTQ080	Same V_RRM (80 V), higher I_F(AV) (15 A device rating), but 0.72 V V_F @ 7.5 A/125 °C and no avalanche rating.	Requires larger heatsink in thermally constrained adapters; unsuitable for designs requiring transient overvoltage robustness.	Select when absolute peak current headroom > thermal efficiency; avoid in unregulated or high-leakage-risk environments.
ON Semiconductor MBR1580CT	Identical D2PAK package and dual-common-cathode configuration, but 0.87 V V_F @ 7.5 A/25 °C and 100 µA I_R @ 125 °C.	Higher conduction loss increases warm-up time and reduces light-load efficiency; not recommended for sub-75 °C ambient designs.	Acceptable only in cost-sensitive, non-thermally-challenged applications where 3.5% efficiency penalty is tolerable.

Compared with VS-15CTQ080 and MBR1580CT, STPS15M80CG-TR uniquely balances low V_F, low I_R, and certified avalanche capability-making it the only option qualified for high-reliability, high-density adapter designs operating continuously at >125 °C junction temperature.

FAQ

What is the maximum continuous current per anode at 100 °C case temperature?

At T_c = 100 °C, the maximum average forward current per anode is 10.2 A, derived from linear derating of the 7.5 A rating at 155 °C using the curve in Figure 3. This value assumes δ = 0.5 duty cycle and proper PCB copper thermal design per Figure 14.

Does STPS15M80CG-TR require a thermal pad under the D2PAK tab?

Yes-a minimum 4 cm² copper area (2 oz thickness) is required beneath the exposed tab to achieve the specified R_th(j-a) of 40 °C/W. Without this, junction temperature will exceed 175 °C at full load, triggering thermal shutdown or accelerated degradation.

Can this device replace STPS15M80CT in through-hole designs?

No-STPS15M80CG-TR uses D2PAK (surface-mount) packaging while STPS15M80CT uses TO-220AB (through-hole). Footprint, thermal path, and assembly process are incompatible; board redesign and requalification are required for substitution.

Is the avalanche rating tested per JEDEC JESD22-A110?

Yes-the 5400 W peak avalanche power rating is validated per JEDEC JESD22-A110 methodology, with pulse duration t_p = 1 µs and junction temperature maintained below 150 °C during testing, as documented in ST application notes AN1768 and AN2025.
