Product details
Overview
STPS20M80CG-TR from STMicroelectronics is a dual common-cathode Schottky rectifier in D2PAK surface-mount package, rated for 80 V repetitive peak reverse voltage and 2 × 10 A average forward current per diode at Tc = 155 °C, with typical forward voltage of 0.67 V at 10 A and 25 °C - optimized for high-frequency SMPS in notebook adapters and LCD TV power supplies.
For engineers reviewing the STPS20M80CG-TR datasheet, STPS20M80CG-TR pinout, STPS20M80CG-TR application, or STPS20M80CG-TR equivalent, this device requires attention to thermal derating in D2PAK layout, avalanche energy handling (6700 W peak), insulated case capability (not applicable here), and dual-diode conduction loss modeling using P = 0.51×IF(AV) + 0.0115×IF²(RMS).
Technical Context
This dual Schottky rectifier integrates two independent anodes sharing a common cathode terminal, enabling synchronous or interleaved output rectification in dual-rail or center-tapped topologies. Its low VF–IR trade-off targets efficiency-critical 100–500 kHz switch-mode converters.
Thermal performance is defined per diode with Rth(j-c) = 2.0 °C/W (D2PAK), requiring PCB copper area ≥10 cm² under tab for rated IF(AV). Avalanche capability is specified for single-pulse conditions (tp < 1 µs, IAR < 20.1 A, VARM = 100 V), validated per AN1768/AN2025.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - maximum reverse blocking voltage per diode; sets upper limit for secondary-side voltage swing in flyback/LLC designs. |
| IF(AV) per diode | 10 A at Tc = 155 °C - defines continuous DC output current capability per channel when mounted on ≥10 cm² 2-oz copper. |
| VF (typ) | 0.67 V at IF = 10 A, Tj = 25 °C - directly determines conduction loss: ~6.7 W per diode at full load. |
| IR (max) | 20 mA at Tj = 125 °C, VR = 80 V - leakage contributes to standby power loss; critical for energy-efficient adapter compliance. |
| Rth(j-c) | 2.0 °C/W per diode - enables junction temperature prediction: ΔTj = Pdiss × 2.0 °C; guides heatsink or PCB thermal design. |
| PARM | 6700 W (tp = 1 µs) - quantifies single-pulse avalanche robustness during transient overvoltage events like MOSFET turn-off spikes. |
Pinout & Package
STPS20M80CG-TR uses the D2PAK (TO-263) thermally enhanced surface-mount package with three terminals: two anodes (A1, A2) and one common cathode (K). The exposed metal tab is electrically connected to the cathode and serves as primary thermal path to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky diode; connects to transformer secondary or switching node in dual-output configuration. |
| A2 | Anode 2 | Input terminal for second Schottky diode; enables independent or paralleled rectification paths without shared anode routing. |
| K | Common cathode | Output node for both diodes; must be routed to low-inductance ground plane or output capacitor; tab soldering required for thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode topology | Enables compact dual-rail output rectification without external cathode tie; reduces board space vs. two discrete diodes. |
| Optimized VF–IR trade-off | 0.67 V @ 10 A / 20 mA @ 125 °C ensures >90% efficiency at light-to-full load in 19 V/4.74 A notebook adapters. |
| Avalanche-rated (6700 W) | Withstands repetitive 100 V/20.1 A transients (tp < 1 µs), eliminating need for external clamping in cost-sensitive AC-DC designs. |
| D2PAK thermal performance | Rth(j-c) = 2.0 °C/W supports 10 A per diode without external heatsink when using ≥10 cm² 2-oz copper under tab. |

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-20CPQ080 | D2PAK package, same 80 V/10 A rating, but VF = 0.72 V @ 10 A (50 mV higher); Rth(j-c) = 2.5 °C/W. | Higher conduction loss increases thermal stress in compact adapters; requires larger copper area for same Tj. | Select when legacy Vishay qualification is mandated; avoid if efficiency >90% at full load is required. |
| ON Semiconductor MBR2080CT | TO-220AB through-hole package (not surface-mount); identical electrical specs but Rth(j-c) = 2.0 °C/W only with heatsink. | Not suitable for automated SMT assembly; adds 120 ms manual soldering time per unit in high-volume production. | Choose only for repair/refurbishment or low-volume prototyping where reflow compatibility is not needed. |
Compared with VS-20CPQ080 and MBR2080CT, STPS20M80CG-TR delivers lower VF and native SMT compatibility in D2PAK, enabling higher power density and automated manufacturing - critical for consumer electronics cost and throughput targets.

FAQ
What is the maximum junction temperature and how is it enforced?
The absolute maximum junction temperature is 175 °C, verified per Table 2. Operation above this threshold risks thermal runaway due to positive temperature coefficient of VF. Designers must ensure Pdiss × Rth(j-c) + Tamb ≤ 175 °C, using Rth(j-c) = 2.0 °C/W and minimum 10 cm² 2-oz copper under the D2PAK tab.
Does STPS20M80CG-TR support avalanche operation in continuous mode?
No - avalanche capability is strictly limited to non-repetitive pulses (tp < 1 µs), with PARM = 6700 W and VARM = 100 V. Continuous avalanche operation is not rated or characterized; sustained reverse overvoltage must be clamped externally using TVS or RCD networks.
How does the common-cathode configuration affect PCB layout?
The shared K terminal simplifies output routing but mandates low-inductance connection to the main output capacitor ground plane. Anode traces (A1/A2) must be symmetrical and length-matched to balance current sharing; asymmetry causes up to 15% current imbalance at 200 kHz switching.
Is the D2PAK package RoHS-compliant and lead-free?
Yes - STPS20M80CG-TR is manufactured in ECOPACK®2-compliant D2PAK packaging, fully lead-free and RoHS-6 compliant (Pb-free, Cd-free, Hg-free, Cr⁶⁺-free, PBB-free, PBDE-free), with halogen-free epoxy meeting IEC 61249-2-21 standards.
