Product details

Overview

B150-13-F from Diodes Incorporated is a 1.0A surface-mount Schottky barrier rectifier with 50V peak repetitive reverse voltage (V_RRM), 0.7V maximum forward voltage at 1.0A, and 0.5mA maximum reverse leakage current at 25°C. It uses SMA package, features guard ring die construction for transient protection, and is used in low-voltage DC power polarity protection and freewheeling paths in switching regulators.

For engineers reviewing the B150-13-F datasheet, B150-13-F pinout, B150-13-F application, or B150-13-F equivalent, key selection criteria include its 50V blocking rating, low 0.7V V_F at rated current, thermal resistance of 20°C/W, surge capability up to 30A, and RoHS-compliant lead-free plating - all critical for high-efficiency, space-constrained power conversion designs.

Technical Context

This Schottky diode operates as a unidirectional, low-loss rectifier optimized for high-frequency switching applications. Its metal-semiconductor junction enables fast recovery (no minority carrier storage) and low forward conduction loss, making it suitable for DC-DC converters, OR-ing circuits, and reverse polarity protection where minimal voltage drop and thermal rise are essential.

The device's guard ring die structure enhances ruggedness against voltage transients, while its SMA package supports automated SMT assembly and provides 20°C/W junction-to-terminal thermal resistance when mounted on 5.0 mm² copper pads - enabling reliable operation up to +150°C junction temperature under 1.0A average load.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum reverse voltage the diode blocks continuously without breakdown; defines safe operating range in 24–48V systems.
I_O	1.0 A - Average rectified output current at T_T = +130°C; sets continuous power handling in thermal-limited PCB layouts.
V_F Max	0.7 V @ I_F = 1.0A - Forward voltage drop determining conduction loss (0.7W at 1A); directly impacts efficiency and thermal design.
I_R Max	0.5 mA @ V_R = 50V, T_A = +25°C - Reverse leakage limiting standby power loss in battery-backed or always-on circuits.
I_FSM	30 A - Non-repetitive peak surge current (8.3ms half-sine); supports inrush and fault-current tolerance in power supplies.
R_θJT	20 °C/W - Junction-to-terminal thermal resistance; used with PCB copper area to calculate junction temperature rise under load.
C_T	110 pF @ V_R = 4V, f = 1MHz - Junction capacitance affecting high-frequency switching noise and EMI in SMPS flyback/freewheeling nodes.

Pinout & Package

Package: SMA (DO-214AC), molded plastic, UL 94V-0 rated, cathode indicated by band on body. Terminal plating: matte tin, lead-free, solderable per MIL-STD-202 Method 208.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry terminal during forward conduction	Connected to lower-potential side (e.g., ground or return path) in polarity protection; source of freewheeling current in inductive loads.
Cathode	Current exit terminal during forward conduction; marked with band	Connected to higher-potential side (e.g., input rail or switch node); clamps reverse voltage in protection configurations.

Key Features

Feature	Design Value
Guard ring die construction	Improves transient voltage immunity and prevents edge breakdown, enhancing reliability in noisy industrial power rails.
Low forward voltage (0.7V @ 1A)	Reduces conduction loss by ~30% vs. comparable silicon rectifiers, lowering thermal stress in compact 1A DC-DC outputs.
30A non-repetitive surge rating	Withstands capacitor inrush and short-circuit events without failure, eliminating need for external current-limiting in many 24V/48V systems.
SMA package with 20°C/W R_θJT	Enables direct thermal coupling to PCB copper, supporting 1.0A continuous operation without heatsink in standard FR4 layouts.

Applications

Power Supply Polarity Protection

DC-DC Converter Freewheeling

Use Scenario: Prevents damage from reversed input voltage in 24V industrial controllers and USB-C powered peripherals.

IC Role / Device Role / Timing Role: Unidirectional blocking element placed in series with input rail; conducts only when anode is more negative than cathode.

Use Value: Eliminates need for P-channel MOSFET solutions, reducing BOM count and layout area while maintaining <0.7V dropout at full load.

Use Scenario: Provides low-loss current path for inductor energy decay in synchronous buck converters operating at 300kHz–1MHz.

IC Role / Device Role / Timing Role: Freewheeling diode across power inductor; conducts during low-side switch off-time to sustain current continuity.

Use Value: Minimizes voltage overshoot and switching loss due to fast recovery and low V_F, improving converter efficiency by 1–2% at 1A output.

OR-ing Diode for Redundant Supplies

Low-Voltage Battery Backup Circuit

Use Scenario: Enables seamless switchover between two 12V/24V backup power sources in telecom line cards and network switches.

IC Role / Device Role / Timing Role: Passive OR-ing element isolating supply domains; conducts only when its anode voltage exceeds cathode by >0.7V.

Use Value: Avoids active controller complexity and gate-drive timing issues, while delivering predictable 0.7V forward drop across both inputs.

Use Scenario: Blocks reverse current from primary battery into backup Li-ion cell in portable medical monitors and handheld test equipment.

IC Role / Device Role / Timing Role: Reverse-blocking diode in battery isolation path; prevents self-discharge and cross-charging during main power failure.

Use Value: Limits standby leakage to ≤0.5mA, extending backup runtime by >20% versus standard silicon diodes with higher I_R.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS15-E3/5AT (Vishay)	Same SMA package, 50V V_RRM, but 0.52V V_F @ 1A (lower loss), 1.0mA I_R @ 25°C (higher leakage)	Better efficiency in thermally constrained 1A designs; less suitable for ultra-low-leakage battery hold-up	Select when minimizing conduction loss dominates over leakage sensitivity
SB150 (ON Semiconductor)	Same 50V/1A rating, SMB package (larger footprint), 0.75V V_F @ 1A, 0.5mA I_R	Higher thermal mass and 15°C/W R_θJA improves power dissipation margin but requires larger board area	Select when board-level thermal management is prioritized over space constraints

Compared with SS15-E3/5AT and SB150, B150-13-F offers balanced trade-offs: lower leakage than SS15-E3/5AT for battery-sensitive designs, and smaller SMA footprint than SB150 for dense layouts - while maintaining identical 50V/1A ratings and Diodes' qualified automotive-grade process control.

FAQ

What is the maximum junction temperature for continuous operation of B150-13-F?

The B150-13-F has an operating junction temperature range of –65°C to +150°C. For continuous 1.0A operation, the datasheet specifies derating above +130°C terminal temperature. With R_θJT = 20°C/W and 0.7W typical power dissipation, junction temperature remains within limit if terminal temperature stays below +130°C - achievable using ≥5.0 mm² copper pad area per terminal.

Is B150-13-F suitable for automotive applications?

B150-13-F is not AEC-Q101 qualified. While Diodes manufactures it in IATF 16949-certified facilities, this specific part lacks automotive qualification documentation. For automotive use, Diodes recommends contacting their applications team for AEC-Q101-qualified alternatives such as the B150AHQ-13-F, which shares identical electrical specs but includes PPAP support and extended temperature validation.

How does the guard ring construction improve reliability?

The guard ring die structure surrounds the active Schottky junction with a doped region that redistributes electric field lines at the semiconductor edge. This suppresses premature avalanche breakdown under transient overvoltage conditions - such as ESD events or inductive kickback - increasing the device's robustness in real-world power rail environments without requiring external TVS components.

Can B150-13-F replace a 1N5819 in existing designs?

Yes - B150-13-F is a direct SMA-package replacement for 1N5819 with identical 1.0A/40V rating (vs. 1N5819's 40V). However, B150-13-F has higher V_RRM (50V), slightly higher V_F (0.7V vs. 0.475V typical), and tighter leakage control (0.5mA max vs. 1.0mA). It is pin-compatible and improves system margin in 48V applications but may require minor efficiency re-evaluation in low-voltage (<5V) circuits.
