Product details
Overview
B180AE-13 from Diodes Incorporated is a 1.0A, 80V high-voltage Schottky barrier rectifier in SMA package, featuring 0.79V max forward voltage at 1.0A and 0.2mA max reverse leakage at 25°C, optimized for polarity protection and DC-DC freewheeling in space-constrained power supplies.
For engineers reviewing the B180AE-13 datasheet, B180AE-13 pinout, B180AE-13 application, or B180AE-13 equivalent, key selection criteria include its low VF (0.79V), 80V VRRM rating, SMA thermal resistance (110°C/W), RoHS-compliant matte tin plating, and guard ring die construction for transient robustness.
Technical Context
This Schottky rectifier uses a planar silicon die with guard ring structure to suppress edge breakdown and improve surge immunity under repetitive transients. Its low forward voltage and fast recovery (no minority carrier storage) enable high-efficiency operation in high-frequency switching topologies.
Designed for surface-mount assembly on FR-4 PCBs with 0.2" × 0.25" copper pads, it delivers 1.0A average output current with thermal derating above 25°C ambient - maintaining 0.5A capability at 100°C per Figure 4 of DS39288 Rev. 4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - Maximum repetitive reverse voltage before breakdown; sets blocking capability in DC-DC flyback and polarity protection circuits. |
| IO (AV) | 1.0 A - Continuous average forward current at +25°C ambient on standard FR-4 board; defines steady-state power handling. |
| VF (max) | 0.79 V @ 1.0A, +25°C - Directly determines conduction loss (0.79W typical per diode); critical for thermal budget in compact designs. |
| IR (max) | 0.2 mA @ 80V, +25°C - Low leakage preserves efficiency in standby and high-impedance bias networks. |
| RθJA | 110 °C/W - Junction-to-ambient thermal resistance on specified 0.4"×0.5" single-sided 2oz Cu board; used to calculate junction temperature rise. |
| CT | 27 pF @ 4V, 1MHz - Junction capacitance affects high-frequency switching noise and EMI in SMPS snubberless designs. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with UL 94V-0 rating, cathode band marking, matte tin-plated terminals, and 0.063g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or switch node) in freewheeling paths; requires low-inductance layout. |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; ties to higher-potential rail (e.g., input bus or inductor output); must withstand full VRRM during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche, enabling stable 80V blocking without premature breakdown under transient stress. |
| Low VF (0.79V max) | Reduces conduction loss by ~30% vs. comparable PN rectifiers, directly improving efficiency in 5–24V DC-DC outputs. |
| SMA package with 110°C/W RθJA | Enables 1.0A operation on standard PCBs without heatsinking; footprint compatible with automated pick-and-place. |
| RoHS-compliant, halogen-free "Green" construction | Meets EU Directive 2015/863/EU with <900ppm Br, <900ppm Cl, <1000ppm Sb; supports environmental compliance in industrial end equipment. |
Applications
| Polariy Protection | DC-DC Freewheeling |
|---|---|
Use Scenario: Reverse-voltage protection at 12V/24V input rails of industrial controllers and IoT gateways. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between connector and main power rail. Use Value: Prevents damage from accidental battery reversal using only 0.79V drop - preserving >96% of input voltage under full load. | Use Scenario: Flyback path in synchronous buck converter output stage operating at 500kHz. IC Role / Device Role / Timing Role: Freewheeling diode across power inductor during high-side FET off-time. Use Value: Enables zero-voltage switching transition with 27pF junction capacitance and no reverse recovery charge, reducing EMI. |
| AC-DC Output Rectification | Re-Circulating Diode |
Use Scenario: Secondary-side rectification in isolated 5V/3A offline flyback adapter. IC Role / Device Role / Timing Role: Output rectifier conducting during transformer reset phase. Use Value: Delivers 1.0A average current with 0.2mA leakage at 50°C ambient, minimizing standby power loss. | Use Scenario: Inductive load suppression in 24V solenoid driver modules. IC Role / Device Role / Timing Role: Clamp diode across relay coil or motor winding. Use Value: Absorbs 30A non-repetitive surge (IFSM) without failure, protecting driving MOSFET from inductive kickback. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB180-E3/54 (Vishay) | Same 80V VRRM, 1.0A IO, but VF = 0.85V max @ 1.0A; SMB package (RθJA = 75°C/W). | Higher thermal performance in SMB, but larger footprint; less suitable for ultra-dense layouts requiring SMA. | Select when board-level thermal management favors lower RθJA over footprint size. |
| SS18 (ON Semiconductor) | 80V VRRM, 1.0A IO, VF = 0.82V max @ 1.0A; SMA package, but IR = 0.5mA @ 25°C (2.5× higher leakage). | Higher leakage limits use in low-power standby circuits where <0.2mA is required. | Select only if cost sensitivity outweighs leakage-critical requirements in always-on systems. |
Compared with SB180-E3/54 and SS18, B180AE-13 offers the lowest VF (0.79V) in SMA form factor with guaranteed 0.2mA IR - making it optimal for efficiency- and space-constrained 12–24V industrial power rails.

FAQ
What is the maximum junction temperature for continuous operation?
The B180AE-13 has an operating junction temperature range of –55°C to +150°C. For continuous 1.0A operation at +25°C ambient, junction temperature rise is calculated as 110°C/W × 0.79W ≈ 87°C, resulting in TJ ≈ 112°C - well within safe limits. Derating is required above 25°C per Figure 4.
Is B180AE-13 suitable for automotive applications?
B180AE-13 meets AEC-Q200 stress test requirements for passive components but is not AEC-Q101 qualified as a discrete semiconductor. It is widely used in non-safety-critical automotive subsystems (e.g., infotainment power rails), provided system-level thermal and surge design margins are validated per DS39288.
Does this part have a specified reverse recovery time (trr)?
No - as a Schottky barrier rectifier, B180AE-13 has no minority carrier storage and therefore no defined reverse recovery time. Its switching behavior is governed by junction capacitance (27pF) and series resistance, enabling clean turn-off in high-frequency converters without recovery spikes.
Can B180AE-13 replace B170AE-13 in existing designs?
Yes - B180AE-13 is a direct upgrade from B170AE-13 with identical package, pinout, and electrical characteristics except for increased VRRM (80V vs. 70V). No layout or thermal changes are needed; the higher blocking voltage improves margin in 24V systems subject to load dump transients.
