Product details
Overview
B1100AE-13 from Diodes Incorporated is a 100 V, 1.0 A high-voltage Schottky barrier rectifier in SMA package, featuring 0.79 V max forward voltage at 1.0 A and 0.2 mA max reverse leakage at 25°C, optimized for polarity protection and DC-DC freewheeling in compact power supplies.
For engineers reviewing the B1100AE-13 datasheet, B1100AE-13 pinout, B1100AE-13 application, or B1100AE-13 equivalent, key selection criteria include its 100 V reverse blocking rating, low VF for efficiency-critical 1 A switching paths, thermal resistance of 110°C/W (J-A), RoHS-compliant lead-free plating, and guard ring die construction for transient robustness.
Technical Context
This Schottky rectifier uses a planar guard ring die structure to suppress edge breakdown and improve surge immunity under repetitive transients. Its low forward voltage drop stems from optimized metal-semiconductor junction design rather than silicon PN junctions, enabling operation up to +150°C junction temperature.
It delivers stable performance across -55°C to +150°C ambient, with reverse leakage rising to 5.0 mA at +125°C - a critical parameter for high-temperature DC-DC output stage selection. Junction capacitance is 27 pF at 4 V reverse bias and 1 MHz, supporting high-frequency freewheeling without excessive ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking range in 48 V or 60 V bus applications. |
| IO | 1.0 A - Average rectified current; supports continuous conduction mode in sub-2 W SMPS outputs. |
| VF Max | 0.79 V @ 1.0 A, 25°C - Low conduction loss enables >92% efficiency in 5 V/1 A buck converter diode path. |
| IR Max | 0.2 mA @ 100 V, 25°C - Minimal leakage preserves standby power in always-on circuits. |
| RθJA | 110°C/W - Thermal limit on FR-4 PCB (0.4" × 0.5", 2 oz Cu); requires derating above 75°C ambient. |
| CT | 27 pF @ 4 V, 1 MHz - Low junction capacitance minimizes switching loss and EMI in 300–500 kHz converters. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount plastic case with cathode band marking; dimensions: 4.00–4.60 mm length × 2.29–2.92 mm width × 1.27–1.63 mm height; weight ≈ 0.063 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential node (e.g., switch node in buck freewheel path). |
| Cathode | Current exit point during forward conduction; marked with band | Connected to output rail or ground return; polarity must be verified before PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche, enabling reliable 30 A non-repetitive surge handling without degradation. |
| Low VF / high efficiency | 0.79 V max drop at full load reduces power loss to ≤0.79 W, easing thermal design in sealed enclosures. |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb), supporting eco-compliance programs. |
| SMA package compatibility | Standard footprint supports automated pick-and-place and reflow soldering per J-STD-020 Level 1 moisture sensitivity. |
Applications
| Power Supply Polarity Protection | DC-DC Converter Freewheeling |
|---|---|
Use Scenario: Reverse-voltage protection at input of 12 V industrial controller powered from external adapter. IC Role / Device Role / Timing Role: Blocking diode placed between connector and LDO input to prevent damage from miswired supply. Use Value: 100 V VRRM withstands accidental 48 V connection; 0.2 mA IR ensures <2.4 µW standby loss. | Use Scenario: Output rectification in 5 V/1 A synchronous buck converter with 400 kHz switching frequency. IC Role / Device Role / Timing Role: Freewheeling path during high-side FET off-time; handles peak currents up to 1.5 A. Use Value: 27 pF CT limits displacement current; 0.79 V VF keeps conduction loss below 0.8 W at full load. |
| AC-DC Auxiliary Supply | Blocking Diode in Solar Charge Controller |
Use Scenario: Secondary-side rectification in 12 V/0.5 A flyback auxiliary supply powering MCU and gate drivers. IC Role / Device Role / Timing Role: Output rectifier operating in discontinuous conduction mode (DCM) at 65 kHz. Use Value: 110°C/W RθJA allows operation at 70°C ambient without heatsink; 150°C max TJ supports sealed transformer designs. | Use Scenario: Reverse-current blocking between 24 V solar panel array and 24 V battery bank. IC Role / Device Role / Timing Role: Isolation diode preventing battery discharge through panel at night. Use Value: 0.2 mA IR at 25°C and 5.0 mA at 125°C ensure minimal self-discharge over seasonal temperature swings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS110-TP (Micro Commercial) | Same 100 V VRRM, 1.0 A IO, but VF = 0.85 V max @ 1 A; RθJA = 120°C/W. | Higher conduction loss reduces efficiency in thermally constrained layouts. | Acceptable where cost is prioritized over thermal margin or efficiency. |
| SB1100 (ON Semiconductor) | Identical 100 V/1 A rating, VF = 0.82 V max @ 1 A; SMB package only (RθJA = 75°C/W). | Lower thermal resistance suits higher ambient environments but requires SMB footprint change. | Preferred when board space allows SMB and ambient exceeds 85°C. |
Compared with SS110-TP and SB1100, B1100AE-13 offers the lowest VF (0.79 V) among SMA-packaged 100 V/1 A Schottkys and balances thermal performance (110°C/W) with standard footprint compatibility - ideal for cost-sensitive, space-constrained 1 A power rails.

FAQ
Is B1100AE-13 suitable for use in automotive applications?
No - B1100AE-13 is not AEC-Q101 qualified and lacks automotive-grade screening, temperature cycling validation, or PPAP documentation. It is rated for industrial (-55°C to +150°C) operation but does not meet automotive reliability or qualification requirements for under-hood or safety-critical systems.
What is the maximum allowable PCB pad size for SMA reflow of B1100AE-13?
The recommended pad layout is defined in Diodes' package outline document: 2.50 mm × 6.50 mm (X × X1) with 1.50 mm gap (G) and 4.00 mm width (C). Exceeding these dimensions risks solder bridging or insufficient thermal relief, especially given its 110°C/W RθJA dependency on controlled copper area.
Does B1100AE-13 have a specified avalanche energy rating?
No - the datasheet does not specify single-pulse avalanche energy (EAS) or repetitive avalanche ratings. Its guard ring die improves transient robustness, but it is not characterized or guaranteed for unclamped inductive switching; external TVS or snubbers are required for such conditions.
Can B1100AE-13 replace B170AE-13 in existing designs?
Only if the circuit's reverse voltage stress remains ≤100 V - B170AE-13 is rated for 70 V VRRM. Swapping increases blocking margin but may alter thermal behavior due to identical VF and RθJA; verify layout thermal relief and peak surge current compliance (both share 30 A IFSM).
