Product details
Overview
SBL1630PT from Diodes Incorporated is a 16A, 30V Schottky barrier rectifier in TO-3P package, featuring low forward voltage drop (0.55V @ 8A, 25°C), high surge capability (250A IFSM), and thermal resistance of 3.5°C/W - designed for low-voltage, high-frequency inverters, freewheeling diodes, and polarity protection circuits.
For engineers reviewing the SBL1630PT datasheet, SBL1630PT pinout, SBL1630PT application, or SBL1630PT equivalent, key selection criteria include peak repetitive reverse voltage (30V), average rectified current at TC=95°C (16A), junction-to-case thermal resistance (3.5°C/W), and RoHS-compliant bright tin-plated leads per MIL-STD-202.
Technical Context
This discrete Schottky rectifier uses guard ring die construction to enhance transient protection and reduce leakage under reverse bias. Its low VFM and high IF(AV) rating enable efficient power conversion in DC-DC stages and output rectification where conduction loss minimization is critical.
Rated for single-phase, half-wave, 60Hz operation with resistive/inductive loads, it requires 20% current derating for capacitive loads. Thermal performance assumes mounting on an external heatsink, with operating junction temperature spanning –65°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum peak repetitive reverse voltage before breakdown; defines safe blocking range in polarity protection and flyback clamp circuits. |
| IO @ TC=95°C | 16 A - Continuous average forward current at case temperature of 95°C; sets usable DC output capacity in high-power SMPS outputs. |
| VFM @ IF=8A, 25°C | 0.55 V - Forward voltage at rated test condition; directly determines conduction loss (4.4W at 8A) and thermal load in high-current paths. |
| IFSM (8.3ms) | 250 A - Non-repetitive surge current rating; supports inrush tolerance during startup in motor drives and UPS systems. |
| RJC | 3.5 °C/W - Junction-to-case thermal resistance; enables heatsink sizing for stable operation at full load without exceeding Tj(max)=150°C. |
| IRM @ 25°C | 0.5 mA - Peak reverse leakage at rated VR; low value ensures minimal standby power loss in battery-backed or energy-sensitive designs. |
| CT @ 1MHz, 4V | 700 pF - Typical junction capacitance; impacts high-frequency switching noise and EMI in >100kHz converters. |
Pinout & Package
TO-3P package: molded plastic case (UL 94V-0), 5.6 g weight, bright tin-plated leads solderable per MIL-STD-202 Method 208. Polarity marked on body; cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point under forward bias | Connected to lower-potential side (e.g., switch node in buck converter); must handle full load current and surge transients. |
| Cathode | Current exit point under forward bias | Connected to higher-potential rail (e.g., output capacitor positive); polarity marking on body confirms orientation for correct PCB layout. |
| Case / Tab | Electrically connected to cathode | Provides thermal path to heatsink; electrically ties cathode potential to mounting surface - isolation required if heatsink is grounded. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves transient voltage immunity and reduces IR drift under surge stress, extending reliability in industrial power supplies. |
| Low VFM (0.55V @ 8A) | Reduces forward conduction loss by ~30% vs. comparable 40V Schottkys, lowering thermal design margin requirements. |
| High IFSM (250A) | Withstands repeated cold-start surges in 12V/24V automotive auxiliary supplies without degradation. |
| RoHS-compliant finish | Bright tin plating meets EU Directive Annex exemptions; compatible with lead-free reflow profiles and legacy SnPb assembly. |
| TO-3P mechanical robustness | UL 94V-0 housing and 3.5°C/W RJC support long-term operation in high-vibration environments like transportation electronics. |
Applications
| DC-DC Converter Output Rectification | Automotive Battery Polarity Protection |

FAQ
Is SBL1630PT still in production?
No - SBL1630PT is officially obsolete and discontinued per Diodes Incorporated's DS23046 Rev. 5 (August 2015). No alternate part is designated by the manufacturer. Aetrix Electronics offers remaining genuine stock with full traceability and supports last-time buy programs for legacy system maintenance.
What is the cathode/anode pin configuration in TO-3P package?
In the TO-3P package, the metal tab is electrically connected to the cathode. The anode is the lead opposite the tab; polarity is marked on the body with a band indicating the cathode end. Mounting the tab to a heatsink ties the cathode to that thermal plane.
Can SBL1630PT replace SBL1640PT in a 40V design?
No - SBL1630PT has VRRM = 30V and must not be used where reverse blocking exceeds 30V. Substituting it for SBL1640PT (40V) risks catastrophic failure under 35–40V transients. Derating rules do not permit cross-voltage-class substitution without circuit-level validation.
What is the maximum allowable case temperature for full 16A current?
The 16A average rectified current rating is specified at TC = 95°C. Operation above this case temperature requires linear derating per Figure 1 in the datasheet: at TC = 110°C, IO drops to ~13.5A; at TC = 125°C, it falls to ~11A. Heatsink design must maintain TC ≤ 95°C under worst-case ambient and airflow conditions.
