Product details
Overview
B530C-13-F from Diodes Incorporated is a 30 V, 5.0 A surface-mount Schottky barrier rectifier in SMC package, featuring 0.55 V max forward voltage at 5.0 A and 0.5 mA max reverse leakage at rated VR, optimized for polarity protection and freewheeling in low-voltage DC/DC converters and industrial power supplies.
For engineers reviewing the B530C-13-F datasheet, B530C-13-F pinout, B530C-13-F application, or B530C-13-F equivalent, this part delivers verified Schottky performance with JEDEC-qualified reliability, RoHS-compliant lead-free plating, and validated thermal resistance (RθJT = 10 °C/W) for high-efficiency 25–150 °C operation.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche failure and supports automated SMT assembly without solderability compromise. Its low VF (0.475 V typ at 5 A, 25 °C) and low IR (0.5 mA max at 30 V, 25 °C) enable minimal conduction loss in continuous forward-biased operation.
Thermal design is enabled by RθJT = 10 °C/W and RθJA = 50 °C/W (on 8 mm² copper pad), allowing sustained 5.0 A average current up to +125 °C ambient when properly heatsinked. Total capacitance remains ≤300 pF at 4 V reverse bias, supporting high-frequency switching up to several MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in polarity protection and flyback clamp circuits. |
| IO | 5.0 A - Average rectified output current; supports continuous 5 A DC load in power supply outputs and motor drive freewheel paths. |
| VF Max | 0.55 V @ 5.0 A, 25 °C - Low forward drop reduces conduction loss and self-heating in high-current, low-voltage rails (e.g., 3.3 V or 5 V systems). |
| IR Max | 0.5 mA @ 30 V, 25 °C - Minimal leakage preserves efficiency in battery-backed or standby circuits where reverse current must be tightly constrained. |
| RθJT | 10 °C/W - Junction-to-terminal thermal resistance enables direct thermal coupling to PCB copper or heatsink, critical for sustained 5 A operation. |
| CT | 300 pF @ 4 V, 1 MHz - Low junction capacitance minimizes switching loss and EMI in high-frequency (>100 kHz) DC/DC topologies. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic, UL 94V-0 rated, with cathode band marking and matte tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to input/source side in rectification; ties to switch node in freewheeling applications to conduct during off-time. |
| Cathode | Forward current exit terminal | Connected to output/load side; carries full load current and defines reference for reverse voltage rating (VRRM = 30 V). |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge breakdown under transient overvoltage, improving surge robustness without external TVS in many 24 V industrial inputs. |
| Low thermal resistance (RθJT = 10 °C/W) | Enables direct thermal path to PCB copper, reducing need for additional heatsinking in space-constrained 5 A power stages. |
| Lead-free, RoHS-compliant plating | Matte tin finish meets MIL-STD-202 solderability requirements and supports Pb-free reflow profiles (J-STD-020 Level 1). |
| JEDEC-qualified reliability | Qualified per AEC-Q standards for high-reliability commercial and industrial use, including extended temperature cycling (-55 to +150 °C). |
Applications
| DC/DC Converter Output Rectification | Polarity Protection Circuit |
|---|---|
Use Scenario: Used as secondary-side synchronous rectifier replacement in 5 V/3.3 V isolated flyback or buck-derived supplies. IC Role / Device Role: Schottky rectifier conducting during transformer demagnetization or switch off-time. Use Value: 0.55 V VF reduces conduction loss vs. standard PN diodes, improving efficiency by ~2–3% at 5 A load. |
Use Scenario: Placed in series with VIN to block reverse battery or miswired supply connections. IC Role / Device Role: Unidirectional current gate preventing damage to downstream regulators and microcontrollers. Use Value: 30 V VRRM covers 24 V nominal systems with margin; 0.5 mA IR avoids battery drain in always-on devices. |
| Motor Drive Freewheeling Diode | Industrial Sensor Power Rail Clamp |
Use Scenario: Mounted across brushed DC motor terminals or H-bridge legs to recirculate inductive kickback current. IC Role / Device Role: Freewheeling path during PWM off-cycle, limiting voltage spike amplitude. Use Value: 100 A IFSM withstands short-duration back-EMF surges; low VF minimizes heat generation during repeated commutation. |
Use Scenario: Connected between sensor supply rail and ground to clamp ESD or cable discharge events. IC Role / Device Role: Low-capacitance (<300 pF) shunt path diverting transients while preserving signal integrity. Use Value: Guard ring structure ensures controlled clamping without snapback; 0.55 V forward threshold enables early turn-on before IC damage thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS53-E3/57T (Vishay) | Same SMC package, 30 V VRRM, but higher VF (0.58 V max @ 5 A) and higher IR (1.0 mA @ 30 V). | Slightly lower efficiency in high-duty-cycle freewheeling; acceptable where leakage tolerance >1 mA. | Select if dual-sourcing required and minor VF/IR trade-off is acceptable for supply chain resilience. |
| MBR530F (ON Semiconductor) | SMC package, 30 V VRRM, identical IO (5 A), but higher RθJA (60 °C/W) and no JEDEC qualification stated. | Requires larger copper area for thermal management; not pre-qualified for automotive-grade reliability programs. | Prefer for cost-sensitive non-automotive designs where JEDEC qualification is not mandated. |
Compared with SS53-E3/57T and MBR530F, B530C-13-F offers the lowest combined VF/IR specification and JEDEC-qualified reliability-making it optimal for thermally constrained, high-efficiency industrial power stages requiring long-term stability.

FAQ
What is the maximum junction temperature for continuous operation?
The B530C-13-F has an operating junction temperature range of –55 °C to +150 °C. For continuous 5.0 A operation, thermal design must ensure TJ stays within this limit-achievable with RθJT = 10 °C/W and adequate PCB copper area per the datasheet's 8 mm² pad recommendation.
Is B530C-13-F suitable for automotive applications?
The standard B530C-13-F is qualified to JEDEC standards for high-reliability commercial use but is not AEC-Q200 qualified. For automotive applications, Diodes offers the pin-compatible B530CQ-13-F variant, which undergoes additional stress testing per AEC-Q200 requirements.
How does the guard ring construction improve reliability?
The guard ring die structure prevents premature edge breakdown during voltage transients by redistributing electric field concentration away from the active junction periphery-enabling reliable operation under repetitive 100 A IFSM surges without degradation or catastrophic failure.
Can B530C-13-F replace a standard PN rectifier in existing designs?
Yes-provided the circuit's reverse voltage does not exceed 30 V and layout accommodates the SMC footprint. The lower VF reduces conduction loss, but designers must verify that reduced reverse recovery time does not induce unintended ringing in snubberless layouts.
