Product details
Overview
STTH1602CFP from STMicroelectronics is a dual-center-tap ultrafast silicon rectifier diode in insulated TO-220FPAB package, rated for 200 V repetitive peak reverse voltage, 10 A average forward current per diode at TC = 130 °C, and 21 ns typical reverse recovery time - optimized for low-loss, high-frequency switch-mode power supplies and DC–DC converters.
For engineers reviewing the STTH1602CFP datasheet, STTH1602CFP pinout, STTH1602CFP application, or STTH1602CFP equivalent, key selection criteria include its insulated 2000 VRMS package, dual-diode thermal coupling behavior, conduction loss equation (P = 0.73 × IF(AV) + 0.020 × IF²(RMS)), and junction-to-case thermal resistance of 5.5 °C/W per diode.
Technical Context
This dual-diode rectifier integrates two independent ultrafast switching elements sharing a common cathode configuration (center-tap topology), enabling synchronous rectification or full-wave bridge operation with reduced layout complexity. Its 21 ns trr and 0.78 V VF(typ) at 150 °C support >100 kHz switching frequencies while minimizing switching and conduction losses.
The TO-220FPAB package provides electrical insulation (2000 VRMS) between mounting tab and internal die, eliminating need for insulating washers in heatsink-mounted designs. Thermal coupling between diodes is modeled via Rth(j-c) = 5.5 °C/W per diode and Rth(c) = 3.5 °C/W, requiring derating when both diodes conduct simultaneously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports input rectification up to 141 V RMS AC or 200 V DC bus applications without avalanche stress. |
| IF(AV) per diode | 10 A at TC = 130 °C - enables compact heatsinking in high-density SMPS where ambient temperature exceeds 85 °C. |
| trr (typ.) | 21 ns - reduces turn-off switching losses and EMI generation in hard-switched topologies above 100 kHz. |
| VF (typ.) | 0.78 V at 8 A, 150 °C - lowers conduction loss by ~15% vs. standard fast recovery diodes at elevated junction temperatures. |
| Rth(j-c) per diode | 5.5 °C/W - defines maximum power dissipation (≈9.1 W per diode at ΔT = 50 °C) before exceeding 175 °C Tj limit. |
| IR (max.) | 60 µA at 125 °C - ensures minimal leakage-induced standby loss in offline adapters and battery-isolated systems. |
| Tj (max.) | 175 °C - allows sustained operation in automotive under-hood or industrial motor drive environments without thermal shutdown. |
Pinout & Package
TO-220FPAB package: insulated plastic housing with metal tab electrically isolated from internal die (2000 VRMS rating); mounting hole centered on tab; recommended torque: 0.55 N·m (max 0.70 N·m).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode leg; connects to primary-side switch node in center-tap forward converter. |
| A2 | Anode 2 | Input terminal for second diode leg; used for complementary phase in push-pull or half-bridge secondary rectification. |
| K | Common Cathode | Output node shared by both diodes; routes rectified DC to output capacitor and load; requires low-inductance PCB routing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 21 ns trr minimizes reverse recovery charge (Qrr) and associated switching loss in high-frequency SMPS. |
| Insulated TO-220FPAB | 2000 VRMS isolation eliminates need for mica washers or silicone pads, reducing assembly cost and thermal interface resistance. |
| High Tj rating | 175 °C maximum junction temperature supports operation in sealed enclosures or high-ambient industrial environments. |
| Low VF at high Tj | 0.78 V typ. at 150 °C improves efficiency retention across temperature range versus conventional fast diodes. |
| Dual-diode integration | Center-tap configuration reduces component count and PCB area vs. discrete diode pairs in full-wave rectifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual-diode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CT | Same die, non-insulated TO-220AB package (no 2000 VRMS isolation); Rth(j-c) = 3.0 °C/W per diode. | Requires insulating hardware for heatsink mounting; better thermal performance but higher assembly cost in safety-critical systems. | Select when thermal budget is tighter than isolation requirement and mechanical mounting permits insulator use. |
| STTH1602CG-TR | Same die, D²PAK surface-mount package; Rth(j-c) = 3.0 °C/W per diode; tape-and-reel packaging. | Enables automated assembly and higher power density; lacks through-hole mechanical robustness for high-vibration environments. | Select for high-volume SMT production where board space is constrained and vibration exposure is low. |
Compared with STTH1602CT and STTH1602CG-TR, the STTH1602CFP uniquely balances electrical isolation, thermal performance, and through-hole reliability - making it optimal for industrial and automotive power supplies where safety certification and mechanical stability are prioritized over pure thermal efficiency or assembly automation.

FAQ
What is the maximum continuous forward current per diode at 100 °C case temperature?
At TC = 100 °C, the STTH1602CFP supports 16 A total device current, meaning 8 A per diode in balanced operation. This is derived from Table 2's IF(AV) rating for TO-220FPAB at TC = 100 °C (Per device: 16 A). Derating must account for thermal coupling using Rth(j-c) = 5.5 °C/W and Rth(c) = 3.5 °C/W.
Does the TO-220FPAB package require a thermal pad or insulating washer?
No - the TO-220FPAB package features an electrically insulated metal tab rated for 2000 VRMS, allowing direct mounting to grounded heatsinks without additional insulation. The datasheet specifies no insulating hardware is needed, and recommended torque is 0.55 N·m.
How does conduction loss compare between STTH1602CFP and standard fast recovery diodes?
Using the provided conduction loss equation P = 0.73 × IF(AV) + 0.020 × IF²(RMS), STTH1602CFP achieves ~22% lower loss at 8 A average current vs. a typical fast diode with VF = 1.1 V. Its 0.78 V VF(typ) at 150 °C further improves efficiency retention under thermal stress.
Can STTH1602CFP be used in reverse polarity protection circuits?
Yes - its 200 V VRRM and low 60 µA IR(max) at 125 °C make it suitable for reverse-battery protection in 24 V and 48 V automotive and industrial systems. The common-cathode configuration allows simple series placement in the positive rail with minimal voltage drop.
