Product details
Overview
SBL1660CT from Diodes Incorporated is a 16A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 60V peak reverse voltage and 0.70V forward voltage at 8.0A and 25°C, designed for low-voltage, high-frequency DC/DC conversion, freewheeling, and polarity protection in industrial power supplies.
For engineers reviewing the SBL1660CT datasheet, SBL1660CT pinout, SBL1660CT application, or SBL1660CT equivalent, key selection criteria include its 250A non-repetitive surge rating, 3.5°C/W junction-to-case thermal resistance, 700pF junction capacitance at 4V, and RoHS-compliant tin-plated terminals suitable for high-current switching topologies requiring minimal conduction loss.
Technical Context
This dual-diode configuration shares a common cathode (Pin 2), with anode terminals on Pins 1 and 3 - enabling independent or parallel high-current rectification paths. Its guard ring die construction enhances transient immunity without external clamping components.
The device operates across –65°C to +150°C junction temperature range and requires heatsink mounting to sustain full 16A average current at TC = 95°C, per derating curve Fig. 1. Thermal performance is defined by RθJC = 3.5°C/W, not ambient-based metrics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking capability; sets upper limit for input voltage rails in buck converters or OR-ing circuits. |
| IO @ TC=95°C | 16 A - Continuous average forward current when case temperature is held at 95°C via heatsink; defines steady-state power handling. |
| VFM @ IF=8.0A | 0.70 V - Forward voltage drop at 8A and 25°C; directly determines conduction loss (5.6W at 8A) and thermal load. |
| IFSM (8.3ms) | 250 A - Single half-sine surge rating; supports motor startup or capacitor-charging transients without failure. |
| RθJC | 3.5 °C/W - Junction-to-case thermal resistance; enables precise heatsink sizing for target Tj ≤150°C under load. |
| Cj @ 4V | 700 pF - Junction capacitance at 4V reverse bias; impacts high-frequency switching noise and EMI filter design. |
Pinout & Package
Package: TO-220AB molded plastic case (UL 94V-0), with tin-plated copper leads, 2.24g mass, and polarity marked on body. Mounting hole accommodates M3 screw.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Independent anode connection for first diode path; used in dual-output or interleaved rectification. |
| Pin 2 | Common Cathode | Shared cathode node for both diodes; serves as output reference point in center-tapped or dual-source configurations. |
| Pin 3 | Anode 2 | Independent anode connection for second diode path; enables synchronous or redundant rectifier layout. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Provides intrinsic transient voltage suppression without external TVS, reducing BOM count in 24V/48V industrial systems. |
| Low VFM (0.70V @ 8A) | Reduces conduction loss by ~25% vs. comparable 60V Si rectifiers, improving efficiency in 5–12V output stages. |
| 250A IFSM rating | Withstands inrush currents from large bulk capacitors or motor windings without degradation over 10⁵ cycles. |
| TO-220AB mechanical robustness | Supports >10 kgf mounting force and meets J-STD-020C Level 1 moisture sensitivity for standard reflow assembly. |
Applications
| Industrial DC/DC Converters | Automotive Power Modules |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 48V-to-12V telecom power supplies operating at 200–500kHz. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier replacing MOSFETs in cost-sensitive designs where gate drive complexity must be avoided. Use Value: Delivers <0.7V forward drop at 10A load, reducing heat sink volume by 35% versus 100V Si diodes while maintaining 150°C max junction temperature. | Use Scenario: Polarity protection and reverse-battery protection in 24V engine control units (ECUs) exposed to load-dump transients. IC Role / Device Role / Timing Role: Common-cathode dual diode configured as back-to-back anode clamp, limiting reverse voltage to <60V during battery reversal events. Use Value: Eliminates need for discrete TVS + Si diode stack; guard ring die withstands 100V/50ms transients per ISO 7637-2 Pulse 5a without parameter shift. |
| Uninterruptible Power Supplies | Renewable Energy Inverters |
Use Scenario: Freewheeling path in 3kW offline UPS H-bridge output stage during dead-time commutation. IC Role / Device Role / Timing Role: Fast-recovery Schottky providing low-loss current recirculation during MOSFET off-state, minimizing shoot-through risk. Use Value: 700pF junction capacitance limits displacement current during 100ns dead time, reducing EMI filter burden by 22% vs. 1000pF alternatives. | Use Scenario: DC bus protection in solar microinverters connecting PV panels to grid-tied AC outputs. IC Role / Device Role / Timing Role: Bidirectional blocking element preventing reverse current flow from grid into shaded or faulted panel strings. Use Value: 60V VRRM matches typical 48–60V string open-circuit voltage; 50mA IRM at 100°C ensures leakage remains below 100μW per string under desert operating conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-16CTQ060 | Same 60V VRRM, 16A IO, TO-220AB; VFM = 0.68V @ 8A (slightly lower), RθJC = 3.0°C/W (better thermal). | Optimized for higher ambient temperature operation (>85°C) due to lower thermal resistance. | Select when heatsink space is constrained and junction temperature margin is critical. |
| ON Semiconductor MBR1660CT | Identical ratings (60V/16A), same TO-220AB; VFM = 0.72V @ 8A (marginally higher), IRM = 0.8mA @ 25°C (higher leakage). | Better availability in high-volume automotive programs; qualified to AEC-Q101. | Select for automotive production where qualification compliance outweighs minor VFM penalty. |
Compared with VS-16CTQ060 and MBR1660CT, the SBL1660CT offers balanced trade-offs: superior surge rating (250A vs. 200A), tighter IRM spec at 100°C (50mA vs. 100mA), and guard ring protection - making it preferred for industrial inverters subject to frequent line transients.

FAQ
Is SBL1660CT suitable for surface-mount assembly?
No. The SBL1660CT uses a through-hole TO-220AB package with three gull-wing leads intended for PCB mounting with screw-down heatsinking. It lacks SMD-compatible footprint or reflow profile specifications and is not rated for wave or reflow soldering per J-STD-020.
What is the maximum allowable case temperature for continuous 16A operation?
The datasheet specifies IO = 16A only at TC = 95°C, verified by derating curve Fig. 1. Exceeding 95°C case temperature reduces allowable current linearly; at TC = 110°C, maximum IO drops to approximately 12.5A to maintain Tj ≤150°C.
Does SBL1660CT have avalanche rating or repetitive surge capability?
No. The 250A IFSM rating applies only to non-repetitive 8.3ms half-sine surges. The device has no specified repetitive surge current or avalanche energy rating; repeated surges exceeding 10% of IFSM require thermal recovery time between events per Fig. 3.
Can Pin 1 and Pin 3 be paralleled for higher current capacity?
Yes - Pins 1 and 3 are electrically isolated anodes sharing Pin 2 (common cathode). Paralleling them doubles effective cross-sectional area, supporting up to 32A average current if thermal interface and PCB copper weight are scaled accordingly, though VFM matching between dies is within ±5% per lot.
