Product details
Overview
BAS16 from Nexperia is a high-speed switching diode in SOT23 (TO-236AB) package, configured as a single discrete silicon PN junction with anode, cathode, and NC terminal. It delivers trr ≤4 ns reverse recovery time, VR = 100 V, IR ≤0.5 µA at 80 V, VF ≤855 mV at 10 mA, and Cd ≤1.5 pF - enabling use in 50 MHz+ signal routing, ESD protection clamping, and fast logic-level translation circuits.
For engineers reviewing the BAS16 datasheet, BAS16 pinout, BAS16 application, or BAS16 equivalent, this page provides verified electrical parameters, validated SOT23 pin mapping, confirmed AEC-Q101 qualification for automotive environments, and real-world switching performance data under IF = 10 mA / VR = 80 V conditions - critical for high-frequency power management and digital interface design.
Technical Context
The BAS16 operates as a unidirectional, low-capacitance switching element optimized for rapid turn-off. Its trr ≤4 ns is measured under standardized IF = 10 mA / IR = 10 mA / RL = 100 Ω conditions, with IR(meas) = 1 mA threshold, confirming suitability for >100 MHz pulse shaping and flyback snubbing.
Thermal resistance Rth(j-a) = 500 K/W (free air, FR4 PCB) and Rth(j-sp) = 330 K/W define its thermal envelope, while AEC-Q101 qualification confirms robustness across −65 °C to +150 °C ambient and junction temperature ranges - essential for under-hood automotive sensor interfaces and industrial PLC I/O stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse voltage (VR) | 100 V - supports 24 V and 48 V industrial bus clamping without breakdown |
| Reverse recovery time (trr) | 4 ns - enables clean switching in 50–100 MHz clock distribution and RF detector circuits |
| Forward voltage (VF) | 855 mV at 10 mA - minimizes conduction loss in low-power logic-level shifters |
| Reverse leakage (IR) | 0.5 µA at VR = 80 V - ensures signal integrity in high-impedance sample-and-hold nodes |
| Diode capacitance (Cd) | 1.5 pF at f = 1 MHz, VR = 0 V - preserves bandwidth in 50 Ω RF front-end coupling paths |
| Junction temperature (Tj) | 150 °C max - allows operation in sealed automotive ECUs without active cooling |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with standard footprint on FR4 PCB; marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Forward current entry point; connects to driver output or supply rail |
| 2 | Not connected | Internally isolated; no electrical function - avoids unintended parasitic coupling |
| 3 | Cathode | Current return path; marked by physical bar; ties to ground or logic-low reference |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114 |
| trr ≤4 ns | Enables sub-10 ns edge fidelity in high-speed digital isolator input stages |
| Low Cd = 1.5 pF | Reduces capacitive loading on 50 Ω transmission lines in RF switch matrices |
| IF(max) = 215 mA | Supports sustained current in LED indicator drivers and microcontroller GPIO protection |
Applications
| Automotive Sensor Interface | High-Speed Logic Translation |
|---|---|
Use Scenario: Clamping transient spikes on LIN bus or crankshaft position sensor outputs. IC Role / Device Role / Timing Role: Discrete high-speed clamp diode placed between signal line and ground rail. Use Value: 4 ns trr prevents signal distortion during 20 kHz sensor pulses; 100 V VR withstands load-dump transients. |
Use Scenario: Level-shifting 3.3 V MCU GPIO signals to 5 V peripheral inputs. IC Role / Device Role / Timing Role: Unidirectional forward-biased switching element in passive translator topology. Use Value: 855 mV VF ensures minimal voltage drop; 1.5 pF Cd avoids timing skew on 10 MHz control lines. |
| RF Detector Circuit | ESD Protection Node |
Use Scenario: Demodulating AM envelope in 433 MHz ISM-band receiver front-end. IC Role / Device Role / Timing Role: Signal-path rectifier operating in small-signal AC mode. Use Value: 4 ns trr maintains fidelity of <100 ns RF carrier cycles; low IR preserves DC offset accuracy. |
Use Scenario: Secondary protection on USB 2.0 D+/D− lines downstream of TVS array. IC Role / Device Role / Timing Role: Fast-turn-on shunt path for residual ESD energy after primary clamping. Use Value: 0.5 µA IR at 80 V prevents leakage-induced false triggers in high-impedance PHY receivers. |
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 |
|---|---|---|---|
| 1N4148W | trr = 4 ns (same), but VF = 1.25 V at 100 mA; IR = 25 nA at 20 V | Higher VF increases power loss in battery-powered logic translators | Prefer BAS16 where low VF at low IF (<10 mA) is critical |
| MMBD4148 | SOT23 package (same), but trr = 5 ns; Cd = 2 pF; AEC-Q101 not specified | Lacks automotive qualification; marginally slower for >50 MHz edge rates | Choose BAS16 for AEC-Q101 compliance and tighter trr spec |
Compared with 1N4148W and MMBD4148, the BAS16 offers lower forward voltage at low currents, guaranteed AEC-Q101 qualification, and identical 4 ns trr - making it optimal for automotive sensor interfaces and ultra-low-power logic translation where leakage and thermal stability are design-critical.

FAQ
Is BAS16 pin-compatible with 1N4148 in SOT23 packages?
No - BAS16 uses Pin 1 = anode, Pin 2 = NC, Pin 3 = cathode; standard 1N4148 in SOT23 (e.g., 1N4148W) uses Pin 1 = anode, Pin 2 = cathode, Pin 3 = NC. The NC pin location differs, requiring PCB layout revision for direct replacement.
What is the maximum continuous forward current for BAS16 at 70 °C ambient?
At Tamb = 70 °C, the derated IF(max) is 170 mA, calculated using Ptot = 250 mW and Rth(j-a) = 500 K/W per datasheet Figure 1 and Table 6 - ensuring Tj remains ≤150 °C with no forced airflow.
Does BAS16 meet RoHS and REACH requirements?
Yes - BAS16 complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound, as documented in Nexperia's official material declarations.
Can BAS16 be used in reverse-biased Zener regulation mode?
No - BAS16 is not characterized or rated for Zener operation; its VZ is undefined, and reverse breakdown is non-uniform above 100 V. Use dedicated Zener diodes (e.g., BZX55C5V1) for regulated voltage references.
