Product details
Overview
BAS16QA-Q from Nexperia is a single high-speed switching diode in a DFN1010D-3 (SOT1215) package, rated for 100 V reverse voltage, 290 mA forward current, and 4 ns reverse recovery time. It serves as a fast-switching signal path component in automotive power management and ECU input conditioning circuits.
For engineers reviewing the BAS16QA-Q datasheet, BAS16QA-Q pinout, BAS16QA-Q application, or BAS16QA-Q equivalent, key selection criteria include trr ≤ 4 ns, IR ≤ 0.5 µA at 80 V, Cd ≤ 1.5 pF, AEC-Q101 qualification, and ultra-thin 0.37 mm profile for space-constrained PCB layouts.
Technical Context
This diode employs a planar silicon epitaxial construction optimized for low charge storage and rapid carrier sweep-out, enabling sub-4 ns reverse recovery under IF = IR = 10 mA test conditions with RL = 100 Ω. Its junction design minimizes minority-carrier lifetime without requiring gold doping.
The DFN1010D-3 package integrates dual cathode terminals (pins 3 and 4) for enhanced thermal conduction and current sharing, while the side-wettable flanks support automated optical inspection of solder joints on fine-pitch automotive PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports 48 V automotive bus transient clamping and 24 V system-level isolation. |
| Reverse Recovery Time (trr) | 4 ns - enables >100 MHz switching in snubberless flyback controllers and high-frequency signal routing. |
| Forward Voltage (VF) | 1.25 V at 150 mA - ensures low conduction loss in 3.3 V/5 V logic-level clamp and protection paths. |
| Reverse Leakage (IR) | 0.5 µA at 80 V, 25 °C - maintains signal integrity in high-impedance sensor interface bias networks. |
| Diode Capacitance (Cd) | 1.5 pF at 0 V, 1 MHz - preserves bandwidth in RF detector and high-speed data line protection circuits. |
| Junction Temperature (Tj) | 150 °C - allows operation in under-hood ECUs with ambient temperatures up to 125 °C and derated power. |
Pinout & Package
DFN1010D-3 (SOT1215) is a 3-terminal, leadless, ultra-thin surface-mount package measuring 1.1 mm × 1.0 mm × 0.37 mm with side-wettable flanks for AOI-compatible reflow soldering. Thermal performance is enhanced by dual cathode pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary P-side connection for forward conduction path; requires trace routing to supply or signal source. |
| 2 | Not Connected | Internally isolated; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress. |
| 3 & 4 | Cathode | Dual K-side terminals share current and reduce thermal resistance to PCB copper; both must be soldered to ground or return plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JS-001 Class 3B. |
| Side-wettable flanks | Enables 100% automated optical inspection of solder joint fillet geometry without X-ray. |
| Low package height (0.37 mm) | Permits stacking beneath connectors or shields in compact ADAS camera modules and radar sensors. |
| Thermal resistance Rth(j-sp) = 55 K/W | Supports 470 mW power dissipation when cathode pad is connected to ≥1 cm² copper area. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Stage |
|---|---|
Use Scenario: Clamping inductive kickback from door lock actuators and mirror motors. IC Role / Device Role / Timing Role: Fast-recovery flyback diode across 12 V solenoid coils. Use Value: 4 ns trr prevents voltage overshoot beyond 100 V during 100 A/ms turn-off transients. |
Use Scenario: Protection of 24 V digital input optocouplers against field-wiring reversals and surges. IC Role / Device Role / Timing Role: Reverse-polarity and transient suppressor on isolated input channel. Use Value: 0.5 µA IR at 80 V avoids false triggering in high-impedance 100 kΩ pull-up configurations. |
| Automotive Infotainment USB Port | Medical Patient Monitor Signal Path |
Use Scenario: ESD and overvoltage protection on USB 2.0 D+/D− lines near connector entry. IC Role / Device Role / Timing Role: Low-capacitance steering diode in I/O rail-to-rail clamp network. Use Value: 1.5 pF capacitance preserves signal integrity up to 480 Mbps without eye diagram degradation. |
Use Scenario: Isolation and level-shifting in analog front-end multiplexer control lines. IC Role / Device Role / Timing Role: High-speed logic-level translator between 3.3 V microcontroller and 5 V analog switch. Use Value: 1.25 V VF at 150 mA ensures clean TTL-compatible switching with <10 ns propagation delay. |
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 NSR0230P2T5G | Lower VR (30 V), higher IF (300 mA), identical trr (4 ns), SOD-923 package (1.0 mm × 0.6 mm). | Not AEC-Q101 qualified; unsuitable for automotive under-hood use but acceptable in consumer USB ports. | Select when board space is tighter than 1.0 mm × 1.0 mm and automotive qualification is unnecessary. |
| Vishay VS-2EDH01HM3/85A | Higher VR (200 V), slower trr (25 ns), TO-277 package (3.5 mm × 2.5 mm), AEC-Q101 qualified. | Used in 48 V DC-DC converter output rectification where speed is secondary to voltage margin. | Select when reverse voltage margin >150 V is required and 25 ns trr is acceptable in power stage topology. |
Compared with NSR0230P2T5G and VS-2EDH01HM3/85A, BAS16QA-Q uniquely balances AEC-Q101 compliance, 100 V rating, 4 ns speed, and 0.37 mm height-making it optimal for space-limited automotive signal conditioning where all three attributes are simultaneously required.

FAQ
Is BAS16QA-Q suitable for 48 V automotive battery monitoring circuits?
Yes. With a 100 V reverse voltage rating and AEC-Q101 qualification, BAS16QA-Q withstands load-dump transients up to ISO 7637-2 Pulse 5a (110 V peak). Its 4 ns trr ensures accurate sampling during fast-switching shunt regulator control loops in battery management IC interfaces.
Can BAS16QA-Q replace BAS216 in an existing design?
No. BAS216 uses SOT23-3 packaging with different pinout (anode-cathode-anode) and higher trr (50 ns). BAS16QA-Q has DFN1010D-3 packaging, dual cathodes, and 4 ns trr-requiring PCB layout revision and thermal validation due to differing Rth(j-a) (410 K/W vs. ~300 K/W).
What is the maximum allowable soldering temperature profile for BAS16QA-Q?
The DFN1010D-3 package supports standard lead-free reflow per JEDEC J-STD-020E: peak temperature 260 °C for ≤30 seconds, with ramp rate ≤3 °C/s pre-peak and cooling rate ≤6 °C/s post-peak. Side-wettable flanks require full solder paste coverage on pins 1, 3, and 4.
Does BAS16QA-Q support bidirectional ESD protection?
No. As a unidirectional diode with anode and cathode terminals, BAS16QA-Q provides only forward-biased clamping. For bidirectional ESD protection, a paired configuration (e.g., two units back-to-back) or dedicated TVS array like PESD5V0S1BA is required.
