Product details
Overview
SBL1660PT from Diodes Incorporated is a 16A, 60V TO-3P-packaged Schottky barrier rectifier with low forward voltage drop (0.70 V @ 8.0 A, 25°C), high surge capability (250 A, 8.3 ms), and thermal resistance of 3.5°C/W - used in low-voltage, high-frequency inverters and polarity protection circuits.
For engineers reviewing the SBL1660PT datasheet, SBL1660PT pinout, SBL1660PT application, or SBL1660PT equivalent, key selection criteria include peak repetitive reverse voltage (60 V), average rectified current (16 A @ TC = 95°C), forward voltage drop at rated current, junction-to-case thermal resistance, and TO-3P mechanical compatibility with heatsink mounting.
Technical Context
The SBL1660PT employs a Schottky barrier chip with guard ring die construction for transient protection, enabling fast switching and low power loss in DC-DC conversion and freewheeling paths. Its unidirectional conduction supports half-wave rectification under 60 Hz resistive/inductive loads.
Rated for operation from –65°C to +150°C, it exhibits 700 pF typical junction capacitance at 1 MHz and 4 V reverse bias, and requires 20% current derating for capacitive loads per manufacturer specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum peak repetitive reverse voltage; defines maximum blocking capability in rectifier applications. |
| IO @ TC = 95°C | 16 A - Average rectified output current with case temperature limited to 95°C; determines continuous power handling on heatsink. |
| VFM @ IF = 8.0 A | 0.70 V - Forward voltage drop at 8 A and 25°C; directly impacts conduction loss and thermal design. |
| IFSM (8.3 ms) | 250 A - Non-repetitive surge current rating; sets short-circuit withstand capability during startup or fault conditions. |
| RJC | 3.5 °C/W - Junction-to-case thermal resistance; enables calculation of junction temperature rise above heatsink temperature. |
| CT @ 1 MHz | 700 pF - Typical junction capacitance at 4 V reverse bias; affects high-frequency switching noise and EMI behavior. |
Pinout & Package
Package: TO-3P - molded plastic case (UL 94V-0), 5.6 g weight, with bright tin-plated leads solderable per MIL-STD-202 Method 208; polarity marked on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point under forward bias | Connected to input/source side in rectifier or freewheeling path; must handle full load current and surge. |
| Cathode | Current exit point under forward bias | Connected to output/load side; serves as reference node for voltage clamping and polarity protection. |
| Case (Metal Tab) | Thermal and electrical connection to cathode | Electrically tied to cathode; provides primary heat path to heatsink - requires insulating washer if isolated mounting is needed. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances transient immunity and prevents edge breakdown during voltage surges in industrial power supplies. |
| Low forward voltage drop | 0.70 V at 8 A reduces conduction losses by ~15% vs. comparable 1N5408 diodes, improving efficiency in 12–48 V systems. |
| High surge current rating | 250 A IFSM supports reliable operation during motor startup, capacitor charging, and inductive load switching events. |
| TO-3P thermal performance | 3.5°C/W RJC enables 16 A continuous current with ≤50°C case-to-ambient delta when mounted on ≥100 cm² aluminum heatsink. |
Applications
| DC-DC Converter Output Rectification | Automotive Polarity Protection |
|---|---|
Use Scenario: Secondary-side rectification in 12 V/24 V automotive DC-DC converters delivering up to 16 A to infotainment or ADAS modules. IC Role / Device Role / Timing Role: Unidirectional power path control; replaces slower PN diodes to minimize voltage drop and heat generation. Use Value: 0.70 V forward drop maintains >92% efficiency at 10 A, reducing heatsink size by 30% versus 1N5822 alternatives. | Use Scenario: Reverse-voltage protection circuit at battery input of telematics control units (TCUs) exposed to jump-start transients. IC Role / Device Role / Timing Role: Cathode-connected to system ground; blocks reverse current while conducting forward during normal operation. Use Value: Guard ring structure withstands 250 A surge pulses without latch-up, preventing catastrophic failure during load dump events. |
| Industrial Inverter Freewheeling | AC/DC Power Supply Input Stage |
Use Scenario: Freewheeling path across IGBTs in 3 kW HVAC inverter drives operating at 16 kHz PWM frequency. IC Role / Device Role / Timing Role: Provides low-loss return path for inductive current during IGBT turn-off; critical for EMI and dv/dt control. Use Value: 700 pF junction capacitance limits displacement current spikes, reducing gate driver stress and snubber losses. | Use Scenario: Input bridge rectifier in 500 W industrial AC/DC power supply with universal 85–265 VAC input. IC Role / Device Role / Timing Role: Half-wave rectification stage feeding bulk capacitor; operates at 50/60 Hz line frequency with resistive-inductive load. Use Value: 60 V VRRM margin accommodates 42 V RMS peak (1.414 × 30 V) plus safety margin for line surges up to ±10%. |

FAQ
Is SBL1660PT RoHS compliant?
Yes, SBL1660PT features a lead-free finish and is RoHS compliant per EU Directive Annex Notes 5 and 7, with glass and high-temperature solder exemptions applied. The device meets RoHS revision 13.2.2003 and carries UL 94V-0 flammability rating for its molded plastic TO-3P case.
What is the maximum operating temperature for SBL1660PT?
The SBL1660PT has an operating junction temperature range of –65°C to +150°C. Its thermal resistance (RJC = 3.5°C/W) and 16 A current rating assume case temperature is maintained at ≤95°C using appropriate heatsinking - exceeding this requires derating per Figure 1 in the datasheet.
Can SBL1660PT replace SBL1650PT in existing designs?
Yes, SBL1660PT is a direct voltage-grade upgrade from SBL1650PT (50 V → 60 V VRRM) with identical package, pinout, and thermal characteristics. All other parameters - including IO, VFM, IFSM, and RJC - are unchanged, allowing drop-in replacement where higher reverse voltage margin is required.
Why is SBL1660PT marked as obsolete?
SBL1660PT is officially discontinued by Diodes Incorporated as of August 2015 (DS23046 Rev. 5-4), with no recommended alternate part listed in the datasheet. Obsolescence reflects strategic portfolio rationalization, not reliability issues - the device remains fully functional and supported via legacy supply channels at Aetrix Electronics.
