Product details

Overview

B1100-13-F from Diodes Incorporated is a 100 V, 1.0 A high-voltage Schottky barrier rectifier in SMA package, optimized for low forward voltage drop (0.79 V @ 1.0 A), low reverse leakage (0.5 mA @ 100 V), and high-frequency free-wheeling in DC-DC converters and polarity protection circuits.

For engineers reviewing the B1100-13-F datasheet, B1100-13-F pinout, B1100-13-F application, or B1100-13-F equivalent, key selection criteria include peak repetitive reverse voltage (100 V), average rectified current (1.0 A), thermal resistance (25 °C/W), RoHS-compliant lead-free plating, and JEDEC-qualified reliability for industrial and automotive-adjacent power systems.

Technical Context

This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche breakdown and sustain stable operation under repetitive surge conditions (30 A IFSM, 8.3 ms half-sine). Its low VF and fast recovery enable high-efficiency operation in switching power supplies without minority-carrier storage delay.

Designed for surface-mount assembly with +260°C/10s solder tolerance, it features cathode-band polarity identification, UL 94V-0 molded plastic housing, and moisture sensitivity level 1 - eliminating bake requirements prior to reflow.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	100 V - Maximum repetitive reverse blocking voltage before breakdown; sets upper limit for DC-DC input rail or AC-DC output stage isolation.
IO (AV)	1.0 A - Continuous average forward current at terminal temperature of +125°C; defines steady-state power handling in compact layouts.
VF Max	0.79 V @ 1.0 A, +25°C - Low conduction loss enables >92% efficiency in 5–12 V output buck converters.
IR Max	0.5 mA @ 100 V, +25°C - Minimal leakage preserves battery life in always-on polarity protection and standby power paths.
RθJT	25 °C/W - Junction-to-terminal thermal resistance supports direct PCB copper pour heatsinking without external thermal vias.
IFSM	30 A - Non-repetitive surge rating allows robust startup and fault-current clamping in motor drive freewheeling paths.

Pinout & Package

Package: SMA (DO-214AC), surface-mount, single-diode configuration with cathode band marking. Dimensions: 4.00–4.60 mm length × 2.29–2.92 mm width × 1.27–1.63 mm height. Weight: ~0.093 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to positive side of source (e.g., switch node in buck converter); must route with low-inductance trace for EMI control.
Cathode	Forward current exit / reverse blocking terminal	Marked by band; ties to output rail or ground return; serves as low-loss return path during inductive flyback.

Key Features

Feature	Design Value
Guard ring die construction	Suppresses edge breakdown during voltage transients, enabling reliable operation in noisy industrial power rails.
Low VF and fast recovery	Eliminates reverse recovery charge (Qrr ≈ 0), reducing switching losses and EMI in >100 kHz DC-DC topologies.
JEDEC-qualified reliability	Meets AEC-Q stress test standards for high-reliability applications including industrial controls and auxiliary automotive subsystems.
Lead-free, halogen-free "Green" packaging	Complies with RoHS 3 (2015/863/EU) and contains <900 ppm Br/Cl, <1000 ppm Sb - suitable for eco-sensitive consumer and medical designs.

Applications

DC-DC Converter Freewheeling

Polarity Protection

Use Scenario: Used across the low-side switch in synchronous buck converters to conduct inductive current during high-side FET off-time.

IC Role / Device Role / Timing Role: Passive freewheeling diode providing continuous current path with minimal conduction loss and zero reverse recovery delay.

Use Value: Enables >93% efficiency at 12 V input / 3.3 V output, 1 A load; reduces thermal footprint vs. silicon PN alternatives.

Use Scenario: Placed in series with V_IN to block reverse supply connection in USB-powered peripherals and IoT sensors.

IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from accidental battery reversal or miswired adapters.

Use Value: Adds <0.8 V dropout at full load while maintaining <0.5 mA leakage in standby - critical for multi-year battery life.

AC-DC Output Rectification

Blocking Diode in Solar Charge Controllers

Use Scenario: Rectifies secondary-side output in offline flyback or forward converters delivering 5–24 V to embedded systems.

IC Role / Device Role / Timing Role: High-frequency rectifier replacing slower PN diodes to minimize ripple and improve dynamic response.

Use Value: Reduces output capacitor size by 30% due to lower ripple current demand and higher effective switching frequency.

Use Scenario: Prevents reverse current flow from battery to PV panel at night in 12 V solar charge management modules.

IC Role / Device Role / Timing Role: Reverse-biased blocking element ensuring energy flows only from panel to battery during daylight.

Use Value: Limits nighttime battery drain to <1 µA typical - extends usable battery capacity over seasonal cycles.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS110-TP (Diodes Inc.)	Same VRRM (100 V), IO (1.0 A), but VF = 0.85 V @ 1 A; SMA package; no JEDEC qualification.	Lacks AEC-Q stress testing; suitable for commercial-grade power supplies but not automotive-adjacent systems.	Select when cost sensitivity outweighs long-term reliability requirements in non-safety-critical designs.
SB1100-E3/52 (Vishay)	Identical VRRM (100 V), IO (1.0 A), VF (0.79 V), but SMB package; RθJT = 30 °C/W; RoHS compliant.	Higher thermal resistance requires larger copper area; SMB footprint differs - board redesign needed.	Choose if existing layout uses SMB or if higher surge margin (IFSM = 50 A) is required for motor drive applications.

Compared with SS110-TP and SB1100-E3/52, B1100-13-F delivers identical electrical performance with JEDEC-qualified reliability in the smaller SMA footprint and superior thermal resistance (25 vs. 30 °C/W), making it optimal for space-constrained, thermally demanding industrial power modules.

FAQ

What is the maximum junction temperature for continuous operation?

The B1100-13-F has an operating temperature range of –65°C to +150°C. Continuous operation at full 1.0 A load requires maintaining terminal temperature ≤ +125°C, per the derating curve - achievable with ≥25 mm² of 2-oz copper on the cathode pad and no additional heatsink.

Is B1100-13-F suitable for automotive applications?

B1100-13-F is JEDEC-qualified and meets AEC-Q stress test standards, but is not officially AEC-Q200 qualified. For automotive use, Diodes offers the pin-compatible B1100BQ-13-F (SMB) and B1100Q-13-F (SMA), which carry full AEC-Q200 certification and extended temperature screening.

How does its thermal resistance compare to SMB-packaged equivalents?

B1100-13-F (SMA) has RθJT = 25 °C/W, while SMB-packaged variants like B1100B-13-F specify RθJT = 30 °C/W. The 5 °C/W difference reflects SMA's lower profile and tighter thermal path to PCB - enabling 12% higher power density in thermally constrained layouts.

Can it replace a standard PN rectifier in an existing design?

Yes - B1100-13-F can directly replace 1 A, 100 V PN rectifiers (e.g., 1N4007) in most cases, offering lower VF (0.79 V vs. 1.1 V), zero reverse recovery, and faster switching. Verify layout clearance for SMA footprint and confirm no voltage overshoot issues due to lack of snubber dependency.
