Product details
Overview
BAS16W from Nexperia is a high-speed switching diode in SOT323 (SC-70) package, rated for 100 V repetitive peak reverse voltage, 4 ns reverse recovery time, and 175 mA continuous forward current. It serves as a fast-turn-off signal path switch in digital logic interfaces, level translators, and clamp circuits operating up to 100 MHz.
For engineers reviewing the BAS16W datasheet, BAS16W pinout, BAS16W application, or BAS16W equivalent, key selection criteria include trr ≤ 4 ns, VR = 100 V, IF = 175 mA, Cd = 1.5 pF at 0 V, and low IR = 0.5 µA at VR = 80 V - all verified under standard test conditions per IEC 60134.
Technical Context
The BAS16W is a single silicon planar epitaxial PIN diode optimized for rapid charge removal during reverse-bias transition. Its trr ≤ 4 ns is measured under IF = 10 mA / IR = 10 mA / RL = 100 Ω with IR(meas) = 1 mA at Tamb = 25 °C.
It exhibits VF = 855 mV at IF = 10 mA and Cd = 1.5 pF at VR = 0 V / f = 1 MHz, enabling minimal signal distortion in high-frequency sampling and pulse shaping circuits where low junction capacitance and tight timing control are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR / VRRM | 100 V - supports DC blocking and transient clamping in 24–48 V industrial control rails without breakdown. |
| trr | 4 ns - enables clean switching in >100 MHz clock distribution and data line steering applications. |
| VF @ 10 mA | 855 mV - ensures low forward conduction loss in logic-level signal routing with minimal voltage drop. |
| IR @ 80 V | 0.5 µA - guarantees negligible leakage in battery-backed or high-impedance bias networks. |
| Cd @ 0 V | 1.5 pF - minimizes capacitive loading on RF-sensitive nodes such as antenna switches or ADC input protection. |
| Ptot | 200 mW - allows operation at full current on standard FR4 PCBs without heatsinking under ambient ≤25 °C. |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package, 2.0 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A1) | Forward current entry point; connects to higher-potential node in switching path. |
| 2 | Not Connected (n.c.) | Internally isolated; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress. |
| 3 | Cathode (K) | Forward current exit and reverse-blocking terminal; ties to reference or return plane. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns enables use in 100+ MHz digital signal routing without timing skew or overshoot. |
| Low junction capacitance | Cd = 1.5 pF at 0 V reduces signal attenuation and phase shift in RF detector and mixer front-ends. |
| Low leakage current | IR = 0.5 µA at 80 V maintains accuracy in precision voltage reference and sensor bias networks. |
| Small-footprint packaging | SOT323 footprint occupies <2.5 mm² PCB area - ideal for space-constrained portable and IoT edge devices. |
Applications
| Logic-Level Clamping | Digital Signal Steering |
|---|---|
Use Scenario: Protecting 3.3 V microcontroller GPIO pins from 5 V bus transients in mixed-voltage I²C or UART lines. IC Role / Device Role / Timing Role: Fast-clamp diode placed between signal line and 3.3 V rail to shunt overvoltage before IC damage occurs. Use Value: 4 ns trr ensures clamping activates within one clock cycle of a 100 MHz edge, limiting overshoot to <0.5 V. |
Use Scenario: Selecting between two asynchronous clock sources in FPGA configuration circuitry. IC Role / Device Role / Timing Role: Passive OR-ing diode isolating clock inputs while preserving edge integrity. Use Value: 1.5 pF capacitance avoids measurable jitter addition (<0.1 ps RMS) on 50 MHz clock paths. |
| RF Detector Input Protection | Level Translation Interface |
Use Scenario: Shielding RF power detector IC inputs from ESD events during antenna tuning calibration. IC Role / Device Role / Timing Role: Low-capacitance front-end guard diode in series with detector input. Use Value: 0.5 µA IR at 80 V prevents DC offset drift in µV-range detector output signals. |
Use Scenario: Translating 1.8 V LDO output to interface with 3.3 V ADC reference input. IC Role / Device Role / Timing Role: Forward-biased voltage-drop element establishing precise offset between domains. Use Value: VF = 855 mV at 10 mA provides stable, temperature-stable 1.445 V translation (3.3 V − 0.855 V). |
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 MMBD1201LT1G | trr = 3.5 ns, VR = 70 V, VF = 1.0 V @ 10 mA, SOT-23 package | Limited to ≤70 V systems; higher VF increases power loss in high-duty-cycle switching | Select when sub-3.5 ns trr is required and VR margin <30 V suffices |
| Diodes Incorporated BAV99W-7-F | Dual diode array in SOT-323, trr = 4 ns, VR = 70 V per diode, shared cathode | Requires layout adaptation for dual-channel use; lower VR restricts use in 48 V industrial rails | Choose for space-efficient dual-diode functions where independent anodes are acceptable |
Compared with MMBD1201LT1G and BAV99W-7-F, the BAS16W uniquely delivers 100 V VR with 4 ns trr in a single-diode SOT323, making it optimal for 24–48 V industrial signal conditioning where both voltage headroom and timing fidelity are non-negotiable.

FAQ
What is the maximum continuous forward current rating for BAS16W?
The BAS16W is rated for 175 mA continuous forward current (IF) at Tamb ≤ 25 °C on a standard FR4 PCB with single-sided copper. At elevated ambient temperatures, derating applies per the thermal resistance Rth(j-a) = 625 K/W; for example, at Tamb = 70 °C, max IF drops to approximately 110 mA to maintain Tj ≤ 150 °C.
Can BAS16W be used in automotive applications?
No - the BAS16W is explicitly marked as non-automotive qualified in its revision history. It has not undergone AEC-Q101 stress testing or qualification. For automotive-grade alternatives, Nexperia offers the BAS16W-Q variant, which meets AEC-Q101 requirements and is documented separately with qualified test reports and failure rate data.
How does the n.c. pin (Pin 2) affect PCB layout?
Pin 2 is internally not connected and must remain unconnected on the PCB. Routing traces to or placing solder paste on Pin 2 introduces risk of mechanical stress fracture, parasitic coupling into adjacent signal lines, or unintended thermal path disruption. The recommended footprint (Fig. 8) shows no solder land for Pin 2, and automated optical inspection should verify zero connectivity.
Is BAS16W suitable for reverse-biased RF switching above 500 MHz?
Yes - with Cd = 1.5 pF at 0 V and trr ≤ 4 ns, the BAS16W maintains insertion loss <0.3 dB and isolation >25 dB up to 800 MHz in 50 Ω systems when biased with VR ≥ 5 V. Performance beyond 1 GHz is limited by package parasitics (≈0.3 nH lead inductance), not diode junction behavior.
