Product details
Overview
STTH1602CG from STMicroelectronics is a dual-center-tap ultrafast silicon rectifier diode in D2PAK package, rated for 200 V repetitive peak reverse voltage, 16 A average forward current per device at Tc = 140 °C, and 21 ns typical reverse recovery time. It serves as a high-efficiency output rectifier in low-voltage, high-frequency DC–DC converters and SMPS secondary-side circuits.
For engineers reviewing the STTH1602CG datasheet, STTH1602CG pinout, STTH1602CG application, or STTH1602CG equivalent, key selection criteria include its dual-diode topology with common cathode configuration, thermal resistance of 1.9 °C/W (junction-to-case, per device), low 0.78 V typical forward voltage at 150 °C/16 A, and suitability for free-wheeling and polarity protection in compact power stages.
Technical Context
This dual-center-tap diode integrates two independent ultrafast switching elements sharing a common cathode terminal (K), enabling synchronous half-wave rectification or dual-output configurations. Its design targets high-frequency operation up to several hundred kHz, supported by low trr (21 ns typ.), low Qrr (16 nC typ. at dIF/dt = 200 A/µs), and minimal forward recovery voltage (2.4 V).
Thermal performance is optimized for conduction-cooled PCB mounting: Rth(j–c) = 1.9 °C/W per device in D2PAK, with junction temperature rated to 175 °C and storage range from –65 °C to +175 °C. The insulated TO-220FPAB variant is not applicable here - STTH1602CG uses standard D2PAK (non-isolated).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum reverse blocking voltage before breakdown; enables use in 12–48 V output SMPS with safety margin. |
| IF(AV) per device | 16 A at Tc = 140 °C - Sustained DC output current capability under real heatsink conditions. |
| trr (typ) | 21 ns - Ultrafast recovery minimizes switching losses and EMI in >200 kHz converters. |
| VF (typ) | 0.78 V at 150 °C / 16 A - Low conduction loss directly reduces thermal load and improves efficiency. |
| Rth(j–c) per device | 1.9 °C/W - Enables direct thermal coupling to copper pour or heatsink; supports 15 W dissipation at ΔT = 28.5 °C. |
| IR (max) | 60 µA at 125 °C - Low leakage preserves efficiency in standby and light-load modes. |
Pinout & Package
STTH1602CG is housed in a surface-mount D2PAK (TO-263AB) package with three terminals: two anodes (A1, A2) and one shared cathode (K). The package features a copper tab for thermal and electrical connection to PCB ground plane or heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode path; connects to transformer secondary winding or input rail in dual-output topology. |
| A2 | Anode 2 | Input terminal for second diode path; enables independent or interleaved rectification with A1. |
| K | Common Cathode | Shared output node; ties both diodes' outputs together for single-rail output or split-rail reference. |
Key Features
| Feature | Design Value |
|---|---|
| Dual center-tap configuration | Two independent anodes with common cathode enable compact dual-output or phase-split rectification without external wiring. |
| Ultrafast recovery (21 ns) | Reduces reverse recovery charge (Qrr = 16 nC typ.) and associated switching loss, critical for >300 kHz DC–DC designs. |
| High junction temperature rating (175 °C) | Supports reliable operation in thermally constrained environments such as sealed industrial power supplies or automotive under-hood modules. |
| Low VF (0.78 V @ 150 °C/16 A) | Minimizes I²R conduction loss and thermal stress on PCB copper, allowing smaller heatsinks or higher power density. |
Applications
| Server VRM Output Stage | Industrial DC–DC Converter |
|---|---|
Use Scenario: High-current, low-voltage (3.3–12 V) output stage in server voltage regulator modules operating at 300–500 kHz. IC Role / Device Role / Timing Role: Dual-anode rectifier delivering parallel current paths to reduce per-path stress and improve thermal distribution. Use Value: 16 A average current per device and 1.9 °C/W Rth(j–c) allow direct mounting to 4-layer PCB copper planes, eliminating discrete heatsinks. | Use Scenario: 24 V input to ±15 V dual-output isolated DC–DC converter for PLC I/O modules. IC Role / Device Role / Timing Role: Center-tapped secondary rectifier providing independent positive and negative output rails with shared cathode return.

Use Scenario: Polarity protection and reverse battery protection circuit in 12 V automotive body control units. IC Role / Device Role / Timing Role: Common-cathode dual diode used in OR-ing configuration to block reverse current while supporting dual power sources. Use Value: 200 V VRRM provides 4× margin over 12 V nominal, and 175 °C Tj rating ensures reliability in under-dash ambient up to 105 °C. | Use Scenario: Primary output rectifier in 48 V telecom DC–DC brick supplying 3.3 V/20 A to baseband processors. IC Role / Device Role / Timing Role: High-efficiency secondary-side rectifier replacing Schottky diodes where higher VRRM and lower leakage are required. Use Value: 60 µA max IR at 125 °C prevents standby current drift, maintaining <100 µA system sleep current in redundant power systems. |

FAQ
What is the pin configuration of STTH1602CG?
STTH1602CG has three terminals: A1 (anode 1), A2 (anode 2), and K (common cathode). In the D2PAK package, A1 and A2 are located on opposite sides of the molded body, while K is the large copper tab on the bottom surface - electrically and thermally connected to the cathode metallization.
Can STTH1602CG replace Schottky diodes in 48 V output applications?
No - STTH1602CG is rated for 200 V VRRM but has a silicon PN junction (VF ≈ 0.78–1.25 V), not a Schottky barrier. It replaces standard ultrafast or fast recovery diodes, not Schottkys. For 48 V outputs, it's suited where low leakage (<60 µA) and high Tj (175 °C) outweigh the need for sub-0.5 V VF.
What is the maximum surge current rating for STTH1602CG?
The non-repetitive peak forward surge current (IFSM) is 80 A for a 10 ms sinusoidal pulse. This rating applies per diode element, meaning each anode–cathode path can withstand 80 A transient current independently under specified thermal conditions.
Is STTH1602CG RoHS compliant and halogen-free?
Yes - STTH1602CG complies with RoHS Directive 2011/65/EU and is halogen-free per STMicroelectronics specification. The D2PAK package uses lead-free matte tin plating and epoxy meeting UL94 V0 flammability rating.
