Product details
Overview
BAS16QA147 from Nexperia is a single high-speed switching diode in an ultra-small DFN1010D-3 (SOT1215) package, featuring trr ≤ 4 ns, IR ≤ 0.5 µA at VR = 80 V, VF ≤ 1.25 V at IF = 150 mA, Cd ≤ 1.5 pF, and VR ≤ 100 V. It serves as a fast signal-path switch in compact DC-DC converter feedback loops and high-frequency rectification stages.
For engineers reviewing the BAS16QA147 datasheet, BAS16QA147 pinout, BAS16QA147 application, or BAS16QA147 equivalent, key selection criteria include reverse recovery time under 4 ns, low leakage below 0.5 µA at 80 V, forward voltage stability up to 150 mA, ultra-thin 0.37 mm profile, and side-wettable flanks for AOI-compatible solder joint inspection.
Technical Context
The BAS16QA147 implements a planar epitaxial silicon switching diode structure optimized for minimal charge storage and rapid carrier sweep-out. Its trr ≤ 4 ns is measured under standardized conditions (IF = 10 mA, IR = 10 mA, IR(meas) = 1 mA, RL = 100 Ω), confirming suitability for >100 MHz switching applications.
Thermal performance is defined by Rth(j-a) = 410 K/W on FR4 with standard footprint and Rth(j-sp) = 55 K/W to cathode solder point, enabling reliable operation up to Tj = 150 °C with derated IF above 75 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| trr | ≤ 4 ns - enables clean switching in >100 MHz clocked circuits without tail current interference |
| IR | ≤ 0.5 µA at VR = 80 V - ensures minimal standby power loss in battery-sensitive signal routing |
| VF | ≤ 1.25 V at IF = 150 mA - maintains low conduction loss in compact load-switch and clamp designs |
| Cd | ≤ 1.5 pF at VR = 0 V - preserves signal integrity in RF detector and high-speed logic interface paths |
| VR | ≤ 100 V - supports use in 48 V industrial bus clamping and 24 V automotive auxiliary circuits |
| Package | DFN1010D-3 (SOT1215) - 1.1 mm × 1.0 mm × 0.37 mm body with side-wettable flanks for AOI-verified reflow |
Pinout & Package
DFN1010D-3 (SOT1215) is a leadless, ultra-thin surface-mount package with visible and solderable side pads, 0.75 mm pitch, and 0.37 mm maximum height. Designed for automated optical inspection and thermal enhancement via cathode-side solder point.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | No connection (n.c.) | Internally unconnected; no electrical function; must remain floating or grounded per layout rules |
| 3 & 4 | Cathode (K) | Common cathode terminals; both electrically tied internally; provide dual thermal and current paths to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|

Applications
| High-Speed Signal Clamping | DC-DC Converter Feedback Path |
|---|---|

IC Role / Device Role / Timing Role: Fast clamping diode limiting signal swing to safe rail voltages within <5 ns. Use Value: Prevents latch-up and ESD damage while maintaining sub-nanosecond response due to trr ≤ 4 ns and Cd ≤ 1.5 pF. | Use Scenario: Isolating feedback voltage divider nodes from switching noise in synchronous buck converters. IC Role / Device Role / Timing Role: High-speed blocking diode in optocoupler-coupled or resistor-divider feedback networks. Use Value: Minimizes phase shift and ripple injection into error amplifiers thanks to low Cd and stable VF across temperature. |
| RF Detector Circuit | Low-Power Logic-Level Translation |
Use Scenario: Demodulating AM signals or detecting RF envelope in sub-GHz ISM band receivers. IC Role / Device Role / Timing Role: Signal-path rectifier converting RF AC to DC baseband with minimal harmonic distortion.

Use Value: Sub-1.25 V VF at 150 mA and <0.5 µA IR ensure accurate threshold crossing and negligible standby loading. |
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 |
|---|---|---|---|
| BAV99W,115 | SC-70 package (2.2 mm × 1.35 mm), trr ≤ 4 ns, VR = 70 V, VF = 1.25 V @ 150 mA | Larger footprint; lower VR rating limits use in 48 V systems | Select when board space allows larger package and VR ≤ 70 V suffices |
| PMEG3010CEH,115 | SOD-123FL package, trr ≤ 3 ns, VR = 30 V, VF = 0.45 V @ 1 A, Schottky architecture | Lower VF but reduced VR; unsuitable for >30 V clamping or reverse-biased isolation | Select only for low-VF priority in ≤30 V logic-level translation or OR-ing |
Compared with BAS16QA147, BAV99W offers similar speed in a larger SC-70 package with lower VR, while PMEG3010CEH delivers lower VF but sacrifices 70 V of reverse blocking capability-making BAS16QA147 the optimal choice for compact, 100 V-rated high-speed switching where leakage and capacitance are critical.

FAQ
What is the maximum reverse voltage rating for BAS16QA147?
The BAS16QA147 has a maximum reverse voltage (VR) rating of 100 V, verified per IEC 60134 absolute maximum ratings. This allows safe operation in 48 V industrial bus protection and 24 V automotive auxiliary circuits where transient spikes may reach 80–100 V. Exceeding this value risks permanent junction breakdown.
Does BAS16QA147 support Automated Optical Inspection (AOI)?
Yes, BAS16QA147 features side-wettable flanks in its DFN1010D-3 (SOT1215) package, enabling reliable AOI of solder joints without requiring X-ray. The 0.37 mm profile and visible copper sidewalls meet IPC-A-610 Class 2/3 inspection requirements for high-volume SMT assembly lines.
What is the thermal resistance from junction to solder point for BAS16QA147?
The BAS16QA147 has a thermal resistance from junction to solder point (Rth(j-sp)) of 55 K/W, measured at the cathode tab. This low value supports efficient heat transfer to the PCB ground plane, allowing sustained 150 mA operation up to 75 °C ambient when mounted on ≥1 cm² cathode copper.
Can BAS16QA147 replace BAS16 in existing designs?
No-BAS16QA147 uses a DFN1010D-3 (SOT1215) package, while legacy BAS16 typically uses SOT23 or SOD323 packages. Pin count, footprint, and thermal behavior differ significantly. Migration requires PCB redesign, requalification of solder profiles, and verification of trr and Cd impact on system timing.
Is BAS16QA147 qualified for automotive applications?
No-BAS16QA147 is explicitly marked as non-automotive qualified in its revision history. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, Nexperia recommends Q-qualified alternatives such as BAS16QHW,115 or PNE20010A,115.
