Product details
Overview
STPS16H100CG-TR from STMicroelectronics is a dual-center-tap high-voltage Schottky rectifier in D²PAK package, rated for 100 V repetitive reverse voltage, 16 A total average forward current (8 A per diode), and 175 °C maximum junction temperature. It delivers low forward voltage drop (0.59 V typ. at 8 A, 125 °C) and negligible switching losses, optimized for high-frequency switch-mode power supplies in AC/DC adapters and on-board DC-DC converters.
For engineers reviewing the STPS16H100CG-TR datasheet, STPS16H100CG-TR pinout, STPS16H100CG-TR application, or STPS16H100CG-TR equivalent, key selection criteria include its dual-diode thermal coupling behavior, avalanche-rated 625 W peak power, low leakage (≤5 mA at 125 °C), and ECOPACK®2-compliant D²PAK packaging for industrial power conversion designs.
Technical Context
This dual-center-tap Schottky rectifier integrates two independent anode-cathode diodes sharing a common cathode terminal (K), enabling synchronous rectification or center-tapped transformer secondary configurations. Its design targets high-efficiency, high-density power conversion where low conduction loss and minimal reverse recovery are critical.
The device features specified avalanche capability (625 W, 10 µs pulse, Tj = 125 °C), junction-to-case thermal resistance of 1.6 °C/W per diode (1.1 °C/W total), and a thermal coupling coefficient (Rth(c) = 0.6 °C/W) that enables accurate junction temperature estimation when both diodes operate simultaneously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in flyback or forward converter secondary side. |
| IF(AV) | 8 A per diode / 16 A total - Average forward current rating at TC = 160 °C; determines continuous power handling with heatsink. |
| VF (typ) | 0.59 V at 8 A, 125 °C - Low forward voltage drop directly reduces conduction loss and improves efficiency in high-current DC-DC stages. |
| IR (max) | 5 mA at 125 °C, VR = VRRM - Low leakage ensures minimal standby power loss and stable operation under high-temperature conditions. |
| Tj (max) | +175 °C - Enables reliable operation in thermally constrained environments such as enclosed power adapters or automotive under-hood modules. |
| PARM | 625 W (10 µs, Tj = 125 °C) - Avalanche energy rating allows robust transient suppression without external snubbers in inductive switching circuits. |
| Rth(j-c) | 1.6 °C/W per diode - Thermal resistance from junction to case supports precise thermal design when mounted on copper heatsinks or PCB thermal pads. |
Pinout & Package
The STPS16H100CG-TR is housed in a surface-mount D²PAK (TO-263) package with three terminals: two anodes (A1, A2) and one shared cathode (K). The exposed metal tab is electrically connected to the cathode and serves as the primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky diode; connects to one leg of center-tapped transformer secondary or split input rail. |
| A2 | Anode 2 | Input terminal for second Schottky diode; connects to opposite leg of center-tapped winding or complementary input path. |
| K | Common Cathode | Shared output node for both diodes; electrically tied to exposed metal tab for thermal and electrical return path. |
Key Features
| Feature | Design Value |
|---|---|
| Negligible switching losses | Zero reverse recovery charge (Qrr ≈ 0) eliminates turn-off loss and EMI in high-frequency SMPS (>100 kHz). |
| High junction temperature capability | Rated up to +175 °C junction temperature enables compact thermal design without derating in sealed enclosures. |
| Good trade-off between leakage and VF | 0.59 V VF at 8 A/125 °C and ≤5 mA IR at same condition balances efficiency and thermal stability. |
| Avalanche capability specified | 625 W peak avalanche power (10 µs) provides built-in surge resilience for inductive load transients. |
| ECOPACK®2 compliance | Meets RoHS and halogen-free requirements with lead-free terminations and environmentally optimized epoxy molding compound. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS16H100CT | Dual-diode D²PAK variant with identical electrical specs but non-tape-and-reel packaging (tube delivery). | Suitable for prototyping or low-volume builds where reel logistics are unnecessary. | Select when tape-and-reel is not required; same thermal and electrical performance. |
| MBR16100CTG | 100 V, 16 A dual Schottky in TO-220AC package; higher Rth(j-c) (2.0 °C/W), no avalanche rating, VF = 0.85 V typ. at 8 A. | Acceptable for lower-frequency (<100 kHz), non-avalanche-critical applications with larger heatsink allowance. | Choose only if D²PAK footprint is unavailable and thermal budget permits +0.26 V higher VF penalty. |

FAQ
What is the thermal coupling behavior between the two diodes in STPS16H100CG-TR?
The device specifies a coupling thermal resistance Rth(c) of 0.6 °C/W between diodes. When both conduct simultaneously, junction temperature rise of Diode 1 equals P₁ × 1.6 + P₂ × 0.6, enabling accurate thermal modeling without assuming full isolation. This coupling supports balanced thermal stress in center-tapped designs.
Can STPS16H100CG-TR replace standard fast recovery diodes in existing 100 kHz flyback designs?
Yes-its zero reverse recovery eliminates turn-off spikes and EMI, reducing snubber losses and filter complexity. However, verify layout thermal relief: the D²PAK tab must be soldered to ≥25 cm² of 35 µm copper for Rth(j-a) ≤ 50 °C/W, per Figure 8 in the datasheet.
Is the common cathode (K) pin electrically isolated from the package tab?
No-the K terminal is internally bonded to the exposed metal tab, which is electrically and thermally part of the cathode. This requires careful PCB isolation: the tab must connect only to cathode net, and adjacent traces must maintain ≥1.5 mm creepage distance from other potentials.
Does STPS16H100CG-TR support paralleling multiple units for >16 A output?
Not recommended-its dual-diode structure is optimized for center-tapped use, not parallel operation. For higher current, select single-die alternatives like STPS30H100CG (30 A) or use external current-sharing resistors with strict matching of VF and thermal mounting.
