Product details
Overview
B530C-13 from Diodes Incorporated is a 30 V, 5.0 A surface-mount Schottky barrier rectifier in SMC package, with maximum forward voltage of 0.55 V at 5.0 A and reverse leakage current ≤0.5 mA at rated VR, designed for polarity protection and freewheeling in low-voltage DC/DC converters and power supply front-ends.
For engineers reviewing the B530C-13 datasheet, B530C-13 pinout, B530C-13 application, or B530C-13 equivalent, key selection criteria include its 30 V reverse voltage rating, low 0.55 V VF at full load, 100 A surge capability, thermal resistance of 10 °C/W (junction-to-terminal), and RoHS-compliant lead-free plating suitable for automated reflow assembly.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient immunity and suppress avalanche-induced failure during inductive switching events. Its low forward voltage drop and fast recovery (inherently <10 ns) minimize conduction loss and enable high-efficiency operation in 100 kHz–1 MHz switching topologies.
The device operates across –55 °C to +150 °C junction temperature range and maintains stable leakage performance up to 100 °C ambient, with thermal resistance of 10 °C/W to terminal enabling direct PCB copper pad heatsinking without external thermal vias in moderate-power applications.
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 forward current at TA = +25°C; derated to ~3.5 A at +100°C ambient per Figure 7. |
| VF Max | 0.55 V @ 5.0 A - Forward voltage at full rated DC current; directly determines conduction loss (≤2.75 W) in continuous operation. |
| IR Max | 0.5 mA @ 30 V, 25°C - Reverse leakage at rated VR; critical for low-power standby and battery-backed systems. |
| RθJT | 10 °C/W - Junction-to-terminal thermal resistance; enables direct thermal coupling to copper pad for passive cooling in SMC footprint. |
| IFSM | 100 A @ 8.3 ms - Non-repetitive surge rating; supports inrush and fault-current handling in DC input stages. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic body with matte tin-plated terminals, cathode indicated by band or notch, weight ≈0.21 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in reverse polarity protection; accepts full 5 A DC load current. |
| Cathode | Forward current exit point | Connected to positive rail; carries output current and sustains 30 V reverse bias when anode is at higher potential. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and surge robustness by preventing edge breakdown during transient overvoltage events. |
| Low VF (0.55 V @ 5 A) | Reduces conduction loss by >30% vs. comparable silicon diodes, enabling higher efficiency in 3.3 V–12 V power rails. |
| Solderable matte tin finish | Ensures reliable wetting and joint integrity under standard SnPb and lead-free reflow profiles (J-STD-020 Level 1). |
| JEDEC-qualified reliability | Meets AEC-Q200 stress test requirements for commercial and industrial environments, including thermal cycling and humidity exposure. |
Applications
| DC Power Input Protection | DC/DC Converter Freewheeling |
|---|---|
Use Scenario: Reverse polarity protection on 5 V–24 V DC inputs of industrial controllers and IoT gateways. IC Role / Device Role / Timing Role: Unidirectional current valve placed between connector and bulk capacitor to block reverse connection damage. Use Value: Prevents catastrophic failure with <0.55 V drop at full load, preserving >98% input voltage under 5 A steady-state current. |
Use Scenario: Freewheeling path in synchronous buck converter output stage operating at 500 kHz. IC Role / Device Role / Timing Role: Low-loss recirculation path for inductor current during high-side FET off-time. Use Value: Enables >94% efficiency at 5 A output by minimizing conduction loss and eliminating reverse recovery charge. |
| Automotive Body Control Module | USB-C Power Delivery Clamp |
Use Scenario: Polarity protection in 12 V automotive body control modules with intermittent load transients. IC Role / Device Role / Timing Role: Primary reverse-blocking element on main power rail before LDOs and microcontrollers. Use Value: Withstands 100 A surge (8.3 ms) and operates reliably from –40 °C to +125 °C ambient per AEC-Q200 alignment. |
Use Scenario: Overvoltage clamp on USB-C VBUS line during hot-plug events and adapter mismatches. IC Role / Device Role / Timing Role: Fast-turn-on shunt path limiting VBUS rise during transient surges above 30 V. Use Value: Low capacitance (300 pF @ 4 V) avoids signal integrity degradation while clamping within nanoseconds. |
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 30 V VRRM and 5 A IO, but VF = 0.52 V @ 5 A; RθJA = 55 °C/W vs. B530C's 50 °C/W. | Higher thermal resistance limits sustained 5 A operation in compact layouts without enhanced copper area. | Select if marginally lower VF is prioritized over thermal headroom in space-constrained designs. |
| MBR530FCT (ON Semiconductor) | 30 V VRRM, 5 A IO, VF = 0.54 V @ 5 A; SMC package, but IR = 0.6 mA @ 25°C (slightly higher leakage). | Marginally higher leakage may impact ultra-low-power sleep modes in battery-powered devices. | Prefer where legacy ON Semi supply chain integration or qualification history is required. |
Compared with SS53-E3/57T and MBR530FCT, the B530C-13 offers tighter IR control (≤0.5 mA), JEDEC-qualified reliability, and optimized thermal interface via 10 °C/W RθJT-making it preferable for thermally demanding, long-life industrial power rails.

FAQ
What is the maximum junction temperature for continuous operation?
The B530C-13 has a specified operating junction temperature range of –55 °C to +150 °C. For continuous DC operation at 5.0 A, thermal design must ensure TJ remains ≤150 °C-achievable with ≥8 mm² copper pad per terminal and minimal ambient rise, per Figure 7 derating curve.
Is the B530C-13 suitable for automotive applications?
The B530C-13 is qualified to JEDEC standards referenced in AEC-Q200 for high reliability in commercial and industrial environments. For automotive-grade use, Diodes offers the pin- and package-compatible B530CQ variant, which undergoes additional stress testing per AEC-Q101.
How does the guard ring construction improve reliability?
The guard ring die structure prevents premature edge breakdown under high dv/dt or reverse-biased transients by redistributing electric field concentration away from the active junction periphery-reducing susceptibility to ESD damage and improving surge survivability in inductive switching circuits.
What is the recommended PCB pad layout for optimal thermal performance?
Per Diodes' SMC package recommendation, use a minimum 8.0 mm² (0.033 mm thick) copper pad per terminal, with no solder mask over pads. The suggested layout (X = 2.50 mm, Y = 3.30 mm, C = 6.90 mm, G = 4.40 mm) ensures mechanical stability and thermal conduction matching the 10 °C/W RθJT specification.
