Product details

Overview

B180B-13-F from Diodes Incorporated is a 1.0A, 80V peak repetitive reverse voltage (V_RRM) Schottky barrier rectifier in SMB package, featuring 0.79V max forward voltage at 1.0A and 0.5mA max reverse leakage at 25°C, used for polarity protection and freewheeling in DC-DC converters and low-voltage power supplies.

For engineers reviewing the B180B-13-F datasheet, B180B-13-F pinout, B180B-13-F application, or B180B-13-F equivalent, key selection criteria include V_RRM, I_O, thermal resistance (R_θJT = 25°C/W), junction temperature range (–65°C to +150°C), and RoHS-compliant lead-free plating for automated assembly.

Technical Context

This discrete Schottky diode uses guard ring die construction to suppress transient-induced failure and supports high-temperature soldering (260°C/10s). Its low VF and fast switching enable high-efficiency operation in high-frequency inverters and freewheeling paths without minority-carrier recovery delay.

Rated for 1.0A average forward current at T_T = +125°C and 30A non-repetitive surge (8.3ms half-sine), it maintains stable IR ≤ 5.0mA up to +100°C and exhibits 80pF total capacitance at 4V reverse bias - critical for EMI-sensitive switching node placement.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	80 V - Maximum blocking voltage before avalanche; sets upper limit for input rail protection in 48V systems.
I_O	1.0 A - Continuous average forward current at terminal temperature 125°C; defines steady-state power handling capability.
V_F Max	0.79 V @ 1.0A, 25°C - Low conduction loss enables >92% efficiency in 5V–12V buck output stages.
I_R Max	0.5 mA @ 80V, 25°C - Minimal leakage preserves battery life in always-on polarity protection circuits.
R_θJT	25 °C/W - Junction-to-terminal thermal resistance; enables direct heatsinking via PCB copper pour without external heatsink.
T_J/T_STG	–65°C to +150°C - Wide operating range supports automotive under-hood and industrial ambient environments.
C_T	80 pF @ 4V, 1MHz - Low junction capacitance minimizes switching noise and ringing in 100kHz–1MHz DC-DC designs.

Pinout & Package

Package: SMB (Surface Mount Body), molded plastic, UL 94V-0 rated, cathode band marked on top surface. Terminal plating: matte tin, lead-free, RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side (e.g., ground or switch node) in freewheeling path; requires adequate copper area for thermal dissipation.
Cathode	Forward current exit / reverse voltage blocking terminal	Marked with band; ties to higher-potential rail (e.g., input or inductor output); determines polarity protection direction.

Key Features

Feature	Design Value
Guard ring die construction	Suppresses edge breakdown during voltage transients, enabling reliable operation in noisy automotive and industrial power rails.
Low VF (0.79V max)	Reduces conduction loss by ≥35% vs. standard PN rectifiers at 1A, directly improving thermal margin in space-constrained layouts.
High-temperature soldering tolerance	Withstands 260°C for 10 seconds - compatible with lead-free reflow profiles without parametric shift or delamination.
Halogen- and antimony-free "Green" compound	Meets <900ppm Br, <900ppm Cl, <1000ppm Sb limits - satisfies strict environmental compliance for EU, China, and automotive OEM requirements.

Applications

DC-DC Converter Freewheeling Diode

Polarity Protection Circuit

Use Scenario: Placed across inductor in buck converter output stage to provide continuous current path during high-side switch off-time.

IC Role / Device Role: Freewheeling diode conducting reverse recovery–free current during discontinuous conduction mode (DCM).

Use Value: 0.79V V_F reduces power loss by ~0.8W vs. 1.1V Si diode at 1A, lowering thermal stress on adjacent ICs and PCB traces.

Use Scenario: Series-connected at power input to prevent damage from reversed battery or supply connections.

IC Role / Device Role: Unidirectional current gate blocking reverse voltage up to 80V while passing 1.0A forward load.

Use Value: 0.5mA I_R at 25°C ensures <1μA standby drain in always-on IoT nodes, extending shelf life and battery runtime.

AC-DC Output Rectification

Re-circulating Diode in Relay/Actuator Drive

Use Scenario: Secondary-side rectifier in isolated flyback or forward converter delivering 5V/12V to logic or interface circuitry.

IC Role / Device Role: High-frequency rectifier converting transformer AC output to regulated DC with minimal ripple contribution.

Use Value: 80pF C_T limits high-frequency noise injection into feedback loop, improving regulation stability without added snubbing.

Use Scenario: Connected across relay coil or solenoid to clamp inductive kickback during de-energization.

IC Role / Device Role: Transient energy dissipation path limiting voltage spike to ≤80V, protecting driving MOSFET or driver IC.

Use Value: 30A I_FSM rating handles repeated 20–50ms coil turn-off surges without degradation over 100k+ cycles.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS18-E3/5AT (Vishay)	V_RRM = 80V, I_O = 1.0A, V_F = 0.85V max @ 1A - 7.6% higher forward drop.	SMB package identical; R_θJT = 30°C/W - 20% higher thermal resistance than B180B-13-F.	Select when Vishay qualification or legacy BOM alignment is required; expect ~0.06W higher conduction loss at full load.
SB180-E3/57T (Vishay)	V_RRM = 80V, I_O = 1.0A, V_F = 0.82V max @ 1A; IR = 0.8mA max @ 25°C - 60% higher leakage.	Same SMB footprint; CT = 100pF - 25% higher capacitance increases EMI risk in high-dV/dt nodes.	Prefer only where Vishay's AEC-Q200 qualification is mandatory; verify leakage impact in battery-backed systems.

Compared with SS18-E3/5AT and SB180-E3/57T, B180B-13-F delivers the lowest V_F (0.79V) and tightest I_R (0.5mA) in its class, offering superior thermal performance (R_θJT = 25°C/W) and lower system-level EMI - making it optimal for compact, high-efficiency DC-DC and battery-critical designs.

FAQ

What is the maximum junction temperature for B180B-13-F?

The absolute maximum junction temperature is +150°C, with derated average forward current beginning at +125°C terminal temperature per the forward current derating curve. Operation above this limit risks permanent parametric shift or metallization failure.

Is B180B-13-F suitable for automotive applications?

B180B-13-F is not AEC-Q200 qualified; however, Diodes offers the automotive-grade B180BQ-13-F variant (separate datasheet DS30018Q) with enhanced testing for temperature cycling, humidity, and vibration - required for under-hood deployment.

How does the SMB package differ from SMA for B180B-13-F?

B180B-13-F uses the larger SMB package (3.30–3.94mm × 4.06–4.57mm) versus SMA (2.29–2.92mm × 4.00–4.60mm), providing 28% greater thermal pad area and 20% higher I_FSM margin - critical for sustained surge handling in industrial motor drives.

What is the meaning of the "-13-F" suffix in B180B-13-F?

The "-13-F" denotes tape-and-reel packaging: "13" indicates 3,000 units per reel, and "F" specifies lead-free, RoHS-compliant matte tin plating per Diodes' standard finish specification - verified per MIL-STD-202, Method 208.
