Product details
Overview
BAS16-Q from Nexperia is a high-speed switching diode in SOT23 package, rated for 100 V reverse voltage, ≤4 ns reverse recovery time, and 215 mA continuous forward current. It serves as a fast-turn-off signal path switch in automotive power management, ECU input protection, and USB port transient suppression circuits.
For engineers reviewing the BAS16-Q datasheet, BAS16-Q pinout, BAS16-Q application, or BAS16-Q equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values, and automotive-grade reliability context - all critical for high-reliability discrete selection.
Technical Context
The BAS16-Q operates as a single silicon planar epitaxial switching diode with low junction capacitance (1.5 pF at 0 V) and tightly controlled reverse recovery behavior (trr ≤ 4 ns under IF = IR = 10 mA, RL = 100 Ω). Its low leakage (0.5 µA at VR = 80 V, 25 °C) supports stable biasing in precision analog front-ends.
Qualified to AEC-Q101, it sustains junction temperatures up to 150 °C and features Rth(j-a) = 500 K/W on FR4 PCB - enabling use in under-hood modules without forced cooling. The n.c. (pin 2) terminal confirms internal isolation and eliminates unintended parasitic coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports 24 V automotive systems with ≥4× safety margin against load-dump transients. |
| Reverse Recovery Time (trr) | ≤4 ns - enables clean switching in >100 MHz clock distribution and data-line clamping. |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - minimizes conduction loss in low-power logic-level signal routing. |
| Diode Capacitance (Cd) | 1.5 pF at VR = 0 V, 1 MHz - preserves signal integrity in high-frequency RF detector and antenna switch paths. |
| Reverse Current (IR) | 0.5 µA at VR = 80 V, 25 °C - ensures negligible standby leakage in battery-backed sensor nodes. |
| Thermal Resistance (Rth(j-a)) | 500 K/W - defines maximum power dissipation (250 mW at Tamb ≤ 25 °C) on standard FR4 layout. |
Pinout & Package
Encapsulated in SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), the BAS16-Q uses a 3-terminal configuration with pin 2 internally unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward current entry point; connects to higher-potential node in series-switch topology. |
| 2 | Not Connected (n.c.) | No internal bond wire; must remain floating or grounded per layout - no routing required. |
| 3 | Cathode (K) | Forward current exit and reverse-blocking terminal; ties to reference or return path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood operation (−40 °C to +150 °C junction), including temperature cycling and HTRB stress. |
| trr ≤ 4 ns | Enables sub-10 ns edge transitions in digital isolator output stages and CAN bus termination networks. |
| Low Cd = 1.5 pF | Reduces capacitive loading on 50 Ω transmission lines - critical for USB 2.0 and LVDS signal integrity. |
| IF = 215 mA continuous | Supports sustained current in LED driver bias paths and microcontroller I/O clamp circuits without derating. |
Applications
| Automotive ECU Input Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting microcontroller GPIO pins from ISO 7637-2 pulse 5a/b transients in engine control units. IC Role / Device Role / Timing Role: Fast-clamp diode in TVS-assisted protection network, conducting surge current before TVS triggers. Use Value: 4 ns trr ensures clamping activation within first 10 ns of transient onset, limiting voltage overshoot to <12 V. |
Use Scenario: ESD and overvoltage suppression on D+ and D− lines of automotive infotainment USB ports. IC Role / Device Role / Timing Role: Low-capacitance shunt diode placed between data line and VBUS/GND to divert ±8 kV HBM ESD events. Use Value: 1.5 pF capacitance avoids signal rise-time degradation beyond USB 2.0 specification (≤1.5 ns). |
| High-Frequency Signal Demodulation | Logic-Level Translation Clamp |
Use Scenario: Envelope detection in 2.4 GHz ISM-band RF receiver front-ends using discrete diode detectors. IC Role / Device Role / Timing Role: Zero-bias switching diode converting RF amplitude to baseband DC voltage. Use Value: Low VF dispersion (715–1250 mV across 1–150 mA) ensures linear demodulation response over wide dynamic range. |
Use Scenario: Level-shifting 1.8 V logic signals to 3.3 V domains while preventing backfeed in mixed-voltage SoC interfaces. IC Role / Device Role / Timing Role: Forward-biased anode-to-3.3 V rail, cathode-to-1.8 V signal - blocking reverse current during low-state transitions. Use Value: 0.5 µA IR at 80 V reverse bias prevents leakage-induced logic corruption in sleep-mode retention paths. |
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 NSS12201LT1G | trr = 3.5 ns (typ), VF = 1.25 V @ 150 mA, same SOT23-3 package | Higher VF increases conduction loss in high-duty-cycle switching; lower trr offers marginal timing advantage | Select when sub-4 ns trr is prioritized over forward loss in burst-mode signal gating. |
| Diodes Incorporated BAV99,215 | Dual-series configuration (two diodes), trr = 4 ns, VF = 1.25 V @ 150 mA, SOT23-3 | Provides dual-channel capability but lacks isolated n.c. pin; not drop-in for single-diode layouts | Choose only when dual-diode topology is required - requires PCB redesign due to different pin mapping. |
Compared with NSS12201LT1G and BAV99,215, the BAS16-Q uniquely combines AEC-Q101 qualification, confirmed n.c. pin (enabling noise-free layout), and balanced VF/trr trade-off optimized for automotive signal integrity - making it preferred for single-diode, space-constrained, and qualification-critical designs.

FAQ
Is BAS16-Q pin-compatible with BAS16 or BAS21?
No. BAS16-Q has pin 2 marked "n.c." (not connected), whereas BAS16 (SOT23) uses pin 2 as cathode and BAS21 (SOD-123) is a two-terminal device. Substitution requires PCB layout revision and validation of reverse recovery performance under identical test conditions (IF = IR = 10 mA, RL = 100 Ω).
What is the maximum allowable soldering temperature profile for BAS16-Q?
The BAS16-Q SOT23 package is rated for lead-free reflow per JEDEC J-STD-020, with peak temperature ≤260 °C for ≤30 seconds. Reflow footprint dimensions (3.3 mm × 1.7 mm pad length, 0.6 mm solder paste stencil) are specified in Figure 8 of the official datasheet to prevent tombstoning or voiding.
Does BAS16-Q support bidirectional ESD protection?
No. As a unidirectional switching diode, BAS16-Q conducts only from anode to cathode. For bidirectional ESD protection, it must be used in back-to-back configuration (e.g., two devices with opposing polarity) or paired with dedicated TVS diodes such as PESD5V0S1BA.
How does the n.c. pin (pin 2) affect PCB layout and thermal performance?
Pin 2 is electrically isolated and thermally disconnected from the die. It may be left unconnected, tied to ground for mechanical stability, or omitted from copper pour - none affects thermal resistance. Rth(j-sp) = 330 K/W is measured from junction to solder point on pins 1 and 3 only, confirming pin 2 contributes no thermal path.
