Product details
Overview
BAS86 from Nexperia is a planar Schottky barrier single diode with integrated guard ring for stress protection, housed in a hermetically sealed SOD80C (LLDS/MiniMelf) glass SMD package. It delivers 900 mV forward voltage at 100 mA, 50 V reverse voltage rating, 4 ns reverse recovery time, and supports 200 mA average forward current - enabling ultra-high-speed switching in compact power rail protection circuits.
For engineers reviewing the BAS86 datasheet, BAS86 pinout, BAS86 application, or BAS86 equivalent, key selection criteria include its low VF for minimal conduction loss, hermetic glass package for reliability in harsh environments, guard ring for ESD/transient robustness, and compatibility with reflow and wave soldering per IPC-7095 standards.
Technical Context
The BAS86 implements a planar Schottky junction architecture with an integrated guard ring to suppress edge breakdown and improve ruggedness under repetitive surge conditions. Its metal–semiconductor interface enables sub-ns switching and eliminates minority-carrier storage delay.
Thermal resistance from junction to ambient is 320 K/W on FR4 PCB with standard footprint, and it operates across −65 °C to +125 °C ambient temperature range. Reverse leakage remains ≤5 µA at 40 V and 25 °C, supporting stable clamping in low-power signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 100 mA | 900 mV - Enables <0.1 W conduction loss at 100 mA in 3.3 V/5 V rail clamp designs |
| VR | 50 V - Supports input protection in industrial I/O and USB power-switching applications |
| trr | 4 ns - Ensures clean switching in >100 MHz clock line clamping and RF detector circuits |
| IF(AV) | 200 mA - Sustains continuous current in low-duty-cycle DC-DC converter catch diodes |
| Cd @ 1 V | 8 pF - Minimizes capacitive loading on high-frequency signal lines (e.g., 2.4 GHz ISM band) |
| IR @ 40 V | 5 µA - Maintains low standby leakage in battery-backed voltage supervisor inputs |
| Rth(j-a) | 320 K/W - Requires no heatsink on standard FR4 PCB; derates linearly above 50 °C ambient |
Pinout & Package
Package: Hermetically sealed glass SOD80C (LLDS/MiniMelf), 3.3–3.7 mm length × 1.45–1.60 mm diameter, tin-plated metal end caps for solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Marked end with black band; connects to lower-potential node in clamping or rectification path |
| 2 | Anode (A) | Unmarked end; ties to higher-potential source or switched rail in protection topology |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge avalanche, enabling reliable operation at 90 % of VR rating under transient stress |
| Hermetic glass encapsulation | Prevents moisture ingress and parametric drift over 15+ year field life in humid industrial enclosures |
| Low VF / high VR ratio | 18:1 ratio supports efficient 5 V rail clamping without thermal runaway at 125 °C junction temp |
| Reflow/wave solder compatible | Withstands peak reflow temps up to 260 °C and wave solder immersion per IPC-J-STD-020D |
Applications
| USB Power Switch Protection | High-Speed Logic Clamp |
|---|---|
Use Scenario: Prevents backfeed and overvoltage damage when dual-source USB ports (e.g., host + charger) share a common VBUS rail. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between VBUS lines to block reverse current while limiting transient overshoot. Use Value: 4 ns trr ensures clamping action completes before logic-level transients propagate to connected PHY ICs. |
Use Scenario: Protects CMOS inputs of FPGA configuration pins or microcontroller GPIOs from ESD-induced overshoot during hot-plug events. IC Role / Device Role / Timing Role: Low-capacitance (8 pF) shunt clamp that conducts only above 50 V, preserving signal integrity below threshold. Use Value: 900 mV VF allows clamping at ~5.5 V on 5 V rails without interfering with valid logic HIGH levels. |
| DC-DC Converter Catch Diode | RF Detector Bias Isolation |
Use Scenario: Used as secondary-side freewheeling diode in non-synchronous buck converters powering low-power sensors (e.g., 3.3 V IoT nodes). IC Role / Device Role / Timing Role: Conducts inductor current during MOSFET off-time; must minimize forward loss and reverse recovery energy. Use Value: 200 mA IF(AV) and 320 K/W Rth(j-a) support continuous operation at 85 °C ambient without derating. |
Use Scenario: Isolates DC bias from RF signal path in 2.4 GHz BLE receiver front-end detector stages. IC Role / Device Role / Timing Role: Blocks DC bias leakage into RF trace while presenting <8 pF capacitance to preserve impedance match. Use Value: 8 pF Cd at 1 V reverse bias maintains <0.1 dB insertion loss at 2.4 GHz per IEEE 802.15.4 channel bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Higher VF (1.0 V @ 100 mA); SOT-23 package; 200 mW Pd rating | Less suitable for space-constrained layouts requiring axial symmetry; higher thermal resistance (400 K/W) | Select when board real estate permits SOT-23 and higher VF is acceptable for cost-sensitive consumer designs |
| 1N5711 | Through-hole DO-35 package; 70 V VR; 1.0 A IFSM; no guard ring | Not suitable for automated SMT assembly; lacks hermetic seal and transient ruggedness | Choose only for legacy through-hole prototyping or high-surge lab test fixtures where SMT is unavailable |
Compared with SBAT54LT1G and 1N5711, the BAS86 offers superior thermal performance (320 vs. 400 K/W), guaranteed guard ring protection, and hermetic reliability - making it preferred for production-grade industrial SMT designs demanding long-term parametric stability.

FAQ
Is the BAS86 suitable for reflow soldering?
Yes. The BAS86's hermetically sealed SOD80C glass package is qualified for lead-free reflow per IPC-J-STD-020D, with peak temperature tolerance up to 260 °C. Its tin-plated metal end caps ensure wetting reliability on standard solder paste profiles, including ramp-soak-reflow cycles.
What does the marking band indicate on the BAS86?
The black marking band identifies Pin 1 as the cathode (K). This polarity marking aligns with the device's schematic symbol and ensures correct orientation during automated placement - critical for maintaining unidirectional clamping behavior in protection circuits.
How does the guard ring improve BAS86 reliability?
The integrated guard ring reduces electric field crowding at the silicon edge, raising the practical breakdown voltage to ≥90 % of rated VR (50 V) under repetitive surge conditions. This prevents premature edge avalanche and extends operational lifetime in transient-prone industrial I/O interfaces.
Can BAS86 replace 1N5817 in low-current applications?
No. While both are Schottky diodes, the 1N5817 has 1 A IF(AV) and TO-220/DO-41 packaging - incompatible with SMT automation and thermally mismatched for BAS86's 200 mA rating. Substitution requires layout redesign, thermal validation, and verification of trr/Cd impact on circuit timing.
