Product details
Overview
B530CE-13 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 0.2 mA max reverse leakage at 30 V and +25°C. It serves as a low-loss polarity protection or freewheeling diode in DC/DC converters and power supplies.
For engineers reviewing the B530CE-13 datasheet, B530CE-13 pinout, B530CE-13 application, or B530CE-13 equivalent, key selection criteria include its 30 V reverse voltage rating, thermal resistance (RθJA = 50 °C/W), junction capacitance (340 pF at 4 V), RoHS-compliant lead-free plating, and SMC package compatibility with automated assembly.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness and suppress avalanche-induced failure during inductive switching. Its low VF and fast recovery enable high-efficiency operation in low-voltage, high-frequency DC/DC topologies.
The device operates across –55°C to +150°C storage range and supports 150 A non-repetitive surge current (8.3 ms half-sine). Thermal performance is characterized with RθJC = 20 °C/W on FR-4 PCB, enabling reliable 5.0 A continuous conduction under defined board layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - maximum repetitive reverse blocking voltage before breakdown |
| IO | 5.0 A - average rectified forward current at TA = +25°C |
| VF Max | 0.55 V @ IF = 5.0 A, TA = +25°C - low conduction loss for high efficiency |
| IR Max | 0.2 mA @ VR = 30 V, TA = +25°C - minimal leakage in blocking state |
| IFSM | 150 A @ 8.3 ms half-sine - surge capability for inductive load turn-off |
| RθJA | 50 °C/W - thermal resistance to ambient on standard FR-4 board |
| CT | 340 pF @ VR = 4 V, f = 1 MHz - junction capacitance affecting high-frequency switching |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case, UL 94V-0 rated, cathode indicated by band or notch. Weight: 0.21 g.
| Pin/Terminal | Circuit Role | Design Meaning |

|---|---|
Use Scenario: Used across inductor output in buck converter to recirculate current during low-side switch off-time. IC Role / Device Role / Timing Role: Freewheeling diode providing continuous current path with minimal voltage drop. Use Value: 0.55 V max VF limits power loss to ≤2.75 W at 5 A, improving converter efficiency and thermal margin. | Use Scenario: Placed in series with input rail to block reverse connection in battery-powered devices. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from incorrect battery insertion. Use Value: 30 V VRRM withstands automotive load-dump transients; 0.2 mA IR ensures negligible standby drain. |

Use Scenario: Output rectification stage in 12 V–24 V AC inverters driving resistive or inductive loads. IC Role / Device Role / Timing Role: High-current output rectifier handling bidirectional energy flow during PWM commutation. Use Value: 150 A IFSM rating supports short-circuit fault currents without bond-wire fusing. | Use Scenario: Reverse-current blocking in USB-C PD power paths where VBUS may be back-driven. IC Role / Device Role / Timing Role: Low-loss isolation diode ensuring source-sink directionality in dual-role ports. Use Value: 340 pF CT minimizes high-frequency coupling; SMC package fits compact USB port layouts. |
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, 5 A IO, but VF = 0.52 V max @ 5 A; slightly higher IR (0.5 mA) | Higher leakage reduces suitability in ultra-low-power always-on circuits | Prefer B530CE-13 where <0.2 mA IR is required at 30 V |
| MBR530FCT (ON Semiconductor) | Identical ratings (30 V/5 A), but TO-277 package - smaller footprint, no leads | Lacks SMC's mechanical robustness and thermal pad area; less suitable for high-reliability industrial PCBs | Choose B530CE-13 when board-level thermal management and IPC-compliant SMT assembly are priorities |
Compared with SS53-E3/57T and MBR530FCT, the B530CE-13 offers tighter IR control and proven SMC thermal performance on FR-4, making it preferred for industrial power supplies requiring long-term leakage stability and manufacturable thermal design.

FAQ
What is the maximum operating temperature for B530CE-13?
The B530CE-13 has a storage temperature range of –55°C to +150°C and is rated for continuous operation at junction temperatures up to +150°C. Derating begins above +25°C ambient per Figure 4 in DS39459, with full 5.0 A current supported only below ~75°C ambient on standard FR-4 board.
Is B530CE-13 suitable for automotive applications?
The B530CE-13 is not AEC-Q101 qualified and lacks automotive-specific qualification testing. While its 30 V VRRM and 150 A surge rating meet some automotive electrical stress requirements, Diodes Incorporated does not authorize its use in safety-critical or engine-bay environments without additional system-level validation.
Does B530CE-13 have a cathode marking?
Yes - the cathode is marked by a visible band or notch on the body of the SMC package, per mechanical data in DS39459. This marking aligns with industry-standard polarity identification and is verified in both top-view and bottom-view diagrams in the datasheet.
Can B530CE-13 replace B520CE-13 or B540CE-13 in existing designs?
Only if the 30 V VRRM rating meets the circuit's peak reverse voltage requirement. B520CE-13 (20 V) and B540CE-13 (40 V) differ in blocking voltage and leakage behavior - substituting B530CE-13 into a 20 V design risks overvoltage stress; in a 40 V design, it may fail prematurely under transient conditions exceeding 30 V.
