Product details
Overview
BAS16QA from Nexperia is a single high-speed switching diode in a DFN1010D-3 (SOT1215) package, designed for signal routing and clamping in high-frequency digital logic interfaces. It delivers trr ≤ 4 ns reverse recovery time, VR = 100 V maximum reverse voltage, and VF = 1.25 V at IF = 150 mA, enabling reliable operation in 5 V and 3.3 V CMOS/TTL level-shifting and protection circuits.
For engineers reviewing the BAS16QA datasheet, BAS16QA pinout, BAS16QA application, or BAS16QA equivalent, key selection criteria include ultra-fast switching performance, low leakage (IR ≤ 0.5 µA at VR = 80 V), minimal capacitance (Cd ≤ 1.5 pF), and compatibility with AOI-enabled SMT assembly on space-constrained PCBs.
Technical Context
The BAS16QA operates as a unidirectional silicon switching diode optimized for discrete-level signal integrity in high-speed digital systems. Its junction structure supports fast carrier recombination, achieving trr ≤ 4 ns under standardized test conditions (IF = IR = 10 mA, RL = 100 Ω). The device exhibits low forward voltage drop (VF = 1.25 V typ. at 150 mA) and negligible capacitance (1.5 pF at 0 V), minimizing signal distortion in data path clamping and transient suppression.
Thermal design is enabled by its ultra-thin 0.37 mm profile and side-wettable flanks (SWF) in the DFN1010D-3 package, delivering Rth(j-sp) = 265 K/W to solder point and supporting continuous IF up to 290 mA at Tamb = 25 °C on standard FR4 PCBs. Pin 2 is internally not connected - confirmed via Nexperia's official pinning diagram and package outline.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | ≤ 4 ns - enables clean edge transitions in >100 MHz digital signal routing without tailing or ringing |
| Reverse Voltage (VR) | 100 V - supports interface protection across industrial I/O, USB, and legacy bus lines |
| Forward Voltage (VF) | 1.25 V @ 150 mA - minimizes power loss and self-heating in high-duty-cycle switching paths |
| Reverse Leakage (IR) | ≤ 0.5 µA @ 80 V - ensures signal integrity in high-impedance logic nodes and sample-hold circuits |
| Diode Capacitance (Cd) | ≤ 1.5 pF @ 0 V - preserves bandwidth in RF detector inputs and high-speed data line clamping |
| Package | DFN1010D-3 (SOT1215) - 1.1 × 1.0 × 0.37 mm, AOI-compatible, side-wettable flanks for solder joint inspection |
| Thermal Resistance (Rth(j-sp)) | 265 K/W - allows direct thermal coupling to copper pour for sustained 290 mA operation on FR4 |
Pinout & Package
Encapsulated in the DFN1010D-3 (SOT1215) leadless plastic package, the BAS16QA features a 0.75 mm pitch, visible side pads for automated optical inspection, and a total height of just 0.37 mm - ideal for ultra-thin portable electronics and dense BGA-adjacent routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward current entry point; connects to higher-potential node in clamping or steering configurations |
| 2 | Not Connected (n.c.) | No internal bond wire or die connection; must remain floating - no PCB trace or thermal pad required |
| 3 & 4 | Cathode (K) | Common cathode terminals - both electrically tied internally; used for low-inductance return path and thermal conduction |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed Switching | trr ≤ 4 ns enables use in 100+ MHz clock distribution networks and ESD-transient clamping without propagation delay penalty |
| Ultra-Small Footprint | 1.1 mm × 1.0 mm body area reduces PCB real estate by >60% vs. SOT23-3, critical for wearables and miniaturized IoT sensors |
| Side-Wettable Flanks (SWF) | Exposed copper sidewalls allow X-ray and AOI verification of solder fillet formation - eliminates hidden void risks in automated assembly |
| Low Capacitance | 1.5 pF Cd minimizes loading on high-impedance analog inputs (e.g., ADC reference dividers) and preserves rise/fall times in LVDS receivers |
| Thermal Performance | Rth(j-sp) = 265 K/W enables 290 mA continuous conduction without external heatsinking on standard FR4 with cathode pad |
Applications
| USB 2.0 Data Line Protection | CMOS Level Shifting |
|---|---|
Use Scenario: Clamping ESD transients on D+ and D− lines of USB 2.0 host/device ports per IEC 61000-4-2 Level 4. IC Role / Device Role / Timing Role: Discrete bidirectional transient voltage suppressor placed between data line and ground, leveraging fast trr to avoid signal distortion during hot-plug events. Use Value: 1.5 pF capacitance prevents signal integrity degradation at 480 Mbps; 100 V VR withstands system-level surge tests without breakdown. | Use Scenario: Translating logic signals between 3.3 V microcontroller GPIO and 5 V peripheral I²C/SPI buses. IC Role / Device Role / Timing Role: Unidirectional level translator using diode-drop biasing, where BAS16QA provides forward conduction path while blocking reverse leakage. Use Value: 1.25 V VF ensures predictable voltage offset; 0.5 µA IR at 80 V prevents false triggering in high-impedance pull-up networks. |
| RF Detector Input Clamping | Digital Logic Signal Steering |
Use Scenario: Protecting the input of a logarithmic RF detector IC from overvoltage during antenna mismatch or transmit leakage. IC Role / Device Role / Timing Role: Front-end clamp diode shunting excess RF energy to ground before it reaches sensitive detector circuitry. Use Value: 4 ns trr avoids rectification artifacts in 900 MHz ISM band applications; low Cd preserves detector linearity up to 2.4 GHz. | Use Scenario: Steering interrupt signals from multiple sensors to a shared MCU input pin using wired-OR configuration. IC Role / Device Role / Timing Role: Anode-connected sensor output, cathode tied to MCU input - isolates sources while enabling logical OR behavior. Use Value: Fast recovery prevents cross-talk between active sensors; 290 mA IF rating supports multiple parallel paths without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR1030HT1G | trr = 3.5 ns (slightly faster); VF = 1.0 V @ 100 mA; same DFN1006-3 package but 0.6 mm × 1.0 mm footprint | Lower VF improves efficiency in battery-powered clamping; smaller footprint eases routing in ultra-dense layouts | Select when <1 ns trr reduction and sub-1 V forward drop justify tighter layout constraints and different land pattern |
| Diodes Incorporated BAV99WQ-7-F | Dual diode in SOT-363; trr = 4 ns; VR = 70 V; Cd = 2 pF; includes matched pair for differential clamping | Supports dual-line protection (e.g., RS-485) in one package; lower VR limits use to 3.3 V/5 V systems only | Select when protecting complementary signal pairs or requiring matched characteristics across two channels |
Compared with NSR1030HT1G and BAV99WQ-7-F, the BAS16QA offers superior VR margin (100 V vs. 70 V), identical trr performance, and larger cathode thermal pad area - making it preferred for industrial I/O protection where voltage headroom and thermal robustness outweigh footprint savings.

FAQ
Is BAS16QA automotive qualified?
No. Per Nexperia's revision history (v.3, October 2024), the BAS16QA is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and is intended for industrial, consumer, and computing applications only. Automotive alternatives - such as the BAS16QAZ variant - are separately qualified and marked with "-Q" suffixes.
What is the function of Pin 2 (n.c.) on BAS16QA?
Pin 2 is internally not connected - confirmed in Nexperia's official pinning table and package drawing. It must remain unconnected on the PCB: no trace, no thermal pad, and no solder mask opening. This terminal serves only as a mechanical alignment aid and does not participate in electrical or thermal performance.
Can BAS16QA replace BAT54-type Schottky diodes?
No - the BAS16QA is a silicon PN junction diode, not a Schottky. While both offer fast switching, the BAS16QA has higher VF (1.25 V vs. ~0.3 V) and lower VR tolerance than typical BAT54 variants (30 V). It is unsuitable for low-voltage (<3 V) or ultra-low-loss applications where Schottky characteristics are essential.
Does BAS16QA require special reflow profile considerations?
Yes. Due to its DFN1010D-3 package with side-wettable flanks, BAS16QA requires precise stencil aperture design (0.35 mm × 0.45 mm per flank) and peak reflow temperature control (260 °C max, per J-STD-020). The 0.37 mm height demands tight coplanarity control (<0.05 mm) to ensure uniform solder wetting on all three terminals.
