Product details
Overview
SDT5H100SB from Diodes Incorporated is a 100 V, 5 A surface-mount trench Schottky rectifier optimized for high-efficiency DC-DC converters and AC-DC adapters. It delivers a maximum forward voltage of 0.62 V at 5 A and 25°C, exhibits only 0.1 mA reverse leakage at 100 V and 25°C, and maintains stable leakage up to 125°C - enabling reliable operation in thermally constrained power stages.
For engineers reviewing the SDT5H100SB datasheet, SDT5H100SB pinout, SDT5H100SB application, or SDT5H100SB equivalent, this device is selected for low-loss freewheeling, synchronous rectification replacement, and high-temperature blocking roles where VF minimization and IR stability are critical design constraints.
Technical Context
This Schottky rectifier uses trench MOS structure to reduce series resistance and enhance carrier injection efficiency, resulting in lower VF than planar Schottkys of comparable rating. Its soft, fast switching behavior minimizes EMI during turn-off transitions in high-frequency switching topologies.
The device operates across –55°C to +150°C junction temperature range with 25°C/W typical thermal resistance (junction-to-case), and is rated for 120 A non-repetitive surge current under 8.3 ms half-sine conditions - supporting robust transient handling in industrial and adapter applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in 48 V and 60 V bus systems. |
| IO (AV) | 5 A - Continuous average forward current at TA = 25°C on FR-4 PCB; derates to ~3.2 A at 100°C ambient per Figure 4. |
| VF (MAX) | 0.62 V @ IF = 5 A, TJ = 25°C - Directly reduces conduction loss in high-current paths; enables >95% efficiency in 12 V → 5 V buck converters. |
| IR (MAX) | 0.1 mA @ VR = 100 V, TJ = 25°C - Low leakage preserves standby power budget; remains ≤20 mA even at 125°C (per datasheet Table). |
| RθJC | 25 °C/W - Enables predictable thermal design when mounted on standard 2 oz copper pad; supports junction temperature estimation under load. |
| IFSM | 120 A @ 8.3 ms - Withstands inrush and short-circuit surges without failure in offline SMPS and PoE-powered equipment. |
Pinout & Package
SDT5H100SB is housed in an SMB (DO-214AA) surface-mount plastic package with cathode band marking. The two-terminal device has no internal connections beyond anode and cathode; polarity is identified by a visible cathode band on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/switching node side; must be routed with low-inductance trace to minimize switching spike coupling. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to output/bus rail; serves as reference for voltage sensing and feedback networks. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~70 mV vs. planar equivalents at 5 A, directly lowering I²R losses in high-duty-cycle converters. |
| Soft, fast switching | Minimizes reverse recovery ringing and EMI generation during diode turn-off - critical for meeting CISPR-32 Class B emissions limits. |
| High-temperature IR stability | Leakage stays ≤20 mA at 125°C, avoiding thermal runaway in sealed enclosures or high-ambient environments like LED drivers. |
| RoHS-compliant, halogen-free | Meets EU RoHS 3 (2015/863/EU) and green manufacturing requirements; contains <900 ppm Br/Cl and <1000 ppm Sb compounds. |
Applications
| DC-DC Buck Converter | AC-DC Adapter Secondary Side |
|---|---|
Use Scenario: High-frequency (300–500 kHz) 12 V → 3.3 V/5 V step-down converter in telecom power modules. IC Role / Device Role: Freewheeling diode replacing synchronous MOSFET in cost-sensitive designs. Use Value: 0.62 V VF enables <0.3 W conduction loss at 5 A, reducing heatsink requirement versus 0.75 V alternatives. |
Use Scenario: Output rectification in 24 W wall-mounted AC-DC adapter for IoT gateways. IC Role / Device Role: Secondary-side output rectifier operating at 100 kHz switching frequency. Use Value: Stable 0.1 mA IR at 25°C and ≤20 mA at 125°C ensures <10 mW standby loss compliance with DOE Level VI. |
| Industrial Motor Drive Snubber | USB-C PD Power Path |
Use Scenario: Flyback snubber clamp in 24 V BLDC motor control H-bridge. IC Role / Device Role: Reverse-biased blocking diode absorbing inductive kick energy. Use Value: 100 V VRRM withstands 2× bus overvoltage transients; 120 A IFSM handles worst-case fault currents. |
Use Scenario: Input protection and reverse-polarity blocking in 60 W USB-C PD sink circuit. IC Role / Device Role: Directional blocking diode placed between VBUS and system rail. Use Value: Low VF minimizes voltage drop across protection path; SMB footprint fits tight layout constraints near connector. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS510-E3/57T (Vishay) | Same SMB package, 100 V/5 A rating, but VF = 0.75 V (max) at 5 A - 130 mV higher conduction loss. | Higher VF increases thermal stress in compact adapters; requires larger copper area for same temperature rise. | Select when legacy qualification or dual-sourcing mandates Vishay footprint compatibility. |
| MBR5100CT (ON Semiconductor) | Dual-die TO-220AB package; 100 V/5 A per diode, VF = 0.72 V (typ), but includes integrated thermal pad for enhanced heatsinking. | Not surface-mount compatible; suited for through-hole designs requiring >5 A parallel operation or forced-air cooling. | Choose only if board assembly process prohibits SMB packages or thermal budget exceeds 25°C/W junction-to-ambient. |
Compared with SS510-E3/57T and MBR5100CT, SDT5H100SB offers the lowest VF among SMB-packaged 100 V/5 A Schottkys, delivering superior efficiency in space-constrained, thermally limited applications - while maintaining full RoHS 3 and halogen-free compliance without trade-offs in surge rating or temperature range.

FAQ
What is the maximum junction temperature for SDT5H100SB?
The SDT5H100SB has an operating junction temperature range of –55°C to +150°C, as specified in the Absolute Maximum Ratings table. This allows reliable use in automotive under-hood environments and sealed industrial enclosures where ambient temperatures exceed 100°C, provided thermal design maintains TJ ≤ 150°C under worst-case load and ambient conditions.
Is SDT5H100SB suitable for synchronous rectification replacement?
Yes - its 0.62 V VF (max) at 5 A and soft switching behavior make it a direct replacement for MOSFET-based synchronous rectifiers in cost-sensitive or low-complexity designs where gate drive overhead is undesirable. It avoids shoot-through risk and eliminates control timing constraints inherent in active rectification.
Does SDT5H100SB require derating for capacitive loads?
Yes - the datasheet specifies that for capacitive loads, the average forward current IO must be derated by 20%. This accounts for higher peak currents during capacitor charging transients, which increase thermal stress and reduce effective current-handling capability compared to resistive or inductive loads.
What is the soldering profile compliance for SDT5H100SB?
SDT5H100SB conforms to JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and supports peak reflow temperatures up to +260°C for 30 seconds. Its matte tin-plated leads meet MIL-STD-202 Method 208 for solderability, ensuring reliable wetting on standard Pb-free and SnPb assembly processes.
