Product details

Overview

B360B-13 from Diodes Incorporated is a 3.0A, 60V surface-mount Schottky barrier rectifier in SMB package, featuring 0.70V forward voltage at 3.0A, 100A non-repetitive surge rating, and 20mA peak reverse current at 100°C - used for polarity protection and free-wheeling in DC-DC converters and automotive body control modules.

For engineers reviewing the B360B-13 datasheet, B360B-13 pinout, B360B-13 application, or B360B-13 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (R_JT = 10°C/W), reverse leakage at elevated temperature, and SMB package compatibility with automated SMT assembly.

Technical Context

This Schottky rectifier uses guard ring die construction to enhance transient immunity and supports high-frequency switching up to several hundred kHz without significant switching loss penalty. Its low V_F and fast recovery (<10ns) enable efficient operation in low-voltage, high-current paths where conduction loss dominates.

The device is rated for 3.0A average forward current at T_T = 100°C with derating to ~1.5A at 125°C ambient, and exhibits 250pF junction capacitance at 4V reverse bias - critical for minimizing ringing in flyback snubber networks and synchronous rectifier gate drive coupling.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60V - maximum repetitive reverse voltage; defines safe blocking capability in 48V automotive or 36V industrial bus applications.
I_O	3.0A @ T_T = 100°C - continuous DC output current rating under defined thermal mounting condition (5mm² copper pad).
V_FM	0.70V @ I_F = 3.0A - forward voltage drop directly determines conduction loss (2.1W at full load) and thermal rise.
I_FSM	100A (8.3ms half-sine) - surge withstand enables robustness against inrush and inductive kick in motor drivers.
R_JT	10°C/W - junction-to-terminal thermal resistance; enables direct heatsinking via PCB copper when mounted on ≥5mm² pad.
C_T	250pF @ 1MHz, 4V - junction capacitance affects high-frequency noise coupling and EMI filter design in SMPS outputs.
T_j	–55°C to +125°C - operational junction temperature range supports under-hood automotive and industrial environments.

Pinout & Package

SMB (DO-214AA) surface-mount package: cathode band marked on one end; anode and cathode terminals only; no internal logic or control pins.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Input current entry point	Connected to source side of power path (e.g., battery+, switch node); must handle full load current and surge.
Cathode	Output current exit point	Connected to load or ground return; polarity-sensitive marking ensures correct orientation in reverse-battery protection.

Key Features

Feature	Design Value
Guard ring die construction	Improves ESD and transient immunity without external TVS, reducing board space in automotive load-dump-prone circuits.
Lead-free / RoHS-compliant finish	Matte tin plating meets J-STD-020C Level 1 moisture sensitivity - eliminates pre-bake requirement for standard SMT reflow.
Low thermal resistance (R_JT = 10°C/W)	Enables direct thermal transfer to PCB copper, supporting compact layout without discrete heatsinks in 3A applications.
100A surge rating (JEDEC method)	Withstands motor stall currents and solenoid de-energization spikes in body electronics without degradation.

Applications

Automotive Battery Reverse Polarity Protection

DC-DC Converter Output Rectification

Use Scenario: Installed between vehicle battery and ECU input to block reverse connection during jump-start or service.

IC Role / Device Role / Timing Role: Unidirectional current valve preventing damage to downstream regulators and microcontrollers.

Use Value: 0.70V V_F limits voltage drop to <1% at 12V systems, preserving cold-crank margin while blocking >60V reverse transients.

Use Scenario: Used as secondary-side rectifier in 5V/3A buck converter powering infotainment USB ports.

IC Role / Device Role / Timing Role: High-efficiency freewheeling diode replacing synchronous MOSFET where cost or layout simplicity is prioritized.

Use Value: 250pF capacitance minimizes high-frequency ringing at 500kHz switching frequency, reducing conducted EMI without added snubbers.

Industrial PLC Input Protection

LED Driver Freewheeling Path

Use Scenario: Protects 24V digital input channels from field-wiring errors and induced surges in factory automation cabinets.

IC Role / Device Role / Timing Role: Polarity guard and transient clamp integrated into input conditioning stage.

Use Value: Guard ring structure sustains 100A surge events per JEDEC test, eliminating need for parallel TVS in DIN-rail mounted I/O modules.

Use Scenario: Provides freewheeling path for inductive current in constant-current LED driver with 36V output.

IC Role / Device Role / Timing Role: Low-loss flyback diode enabling >92% efficiency at 3A output with minimal thermal derating.

Use Value: R_JT = 10°C/W allows full 3A load on standard 2oz copper without thermal vias - simplifying thermal design in space-constrained lighting housings.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SB360-E3/52 (Vishay)	Same 60V/3A rating; V_F = 0.72V @ 3A; R_JT = 12°C/W; SMB package.	Higher thermal resistance requires larger copper area for same power dissipation.	Preferred when Vishay's qualification pedigree is required for industrial safety certifications.
SS36 (ON Semiconductor)	V_F = 0.75V @ 3A; I_FSM = 80A; R_JT = 15°C/W; SMB package.	Lower surge rating and higher V_F reduce margin in high-inrush motor control.	Acceptable for cost-sensitive consumer power supplies where 80A surge is sufficient.

Compared with SB360-E3/52 and SS36, B360B-13 delivers lower forward voltage and superior thermal resistance - enabling higher sustained current in thermally constrained layouts without sacrificing surge robustness.

FAQ

What is the cathode marking convention for B360B-13?

The cathode is identified by a distinct band printed on the SMB package body, aligned with the cathode terminal. A semicircular notch may also be present on the same side as the band - both features indicate cathode polarity and must align with PCB silkscreen markings during placement.

Can B360B-13 replace B360A-13 in an existing design?

Yes, but thermal performance differs: B360B-13 (SMB) has higher R_JA than B360A-13 (SMA), so PCB copper area must be increased by ~30% to maintain equivalent junction temperature at 3.0A. Layout revision is recommended before substitution.

Is B360B-13 suitable for synchronous rectification?

No - it is a passive Schottky diode, not a controlled switch. It cannot be actively gated like a MOSFET. However, its low V_F and fast recovery make it a common choice where synchronous rectifier ICs or controllers are not deployed due to cost or complexity constraints.

Does B360B-13 require derating for capacitive loads?

Yes - per datasheet note, average forward current must be reduced by 20% when used with capacitive loads (e.g., bulk input filtering) to prevent excessive peak current stress during charging cycles, ensuring long-term reliability under repeated cold-start conditions.
