Product details
Overview
BAS16-QR from Nexperia is a high-speed switching diode in SOT23 package, rated for 100 V repetitive peak reverse voltage (VRRM), 4 ns reverse recovery time (trr), and 215 mA continuous forward current (IF). It features low leakage (0.5 µA at VR = 80 V), low capacitance (1.5 pF), and AEC-Q101 qualification for automotive signal routing and clamping circuits.
For engineers reviewing the BAS16-QR datasheet, BAS16-QR pinout, BAS16-QR application, or BAS16-QR equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, automotive-grade reliability context, and real-world switching use cases - all grounded in Nexperia's official 2021 product data sheet.
Technical Context
The BAS16-QR operates as a single-element silicon planar epitaxial switching diode with an anode-cathode structure optimized for fast transient response. Its trr ≤ 4 ns is measured under IF = IR = 10 mA, RL = 100 Ω, and IR(meas) = 1 mA at 25 °C, confirming suitability for >100 MHz digital signal edge control.
Thermal resistance from junction to ambient is 500 K/W on FR4 PCB (single-sided copper), and its 150 °C maximum junction temperature supports operation in under-hood automotive environments. The n.c. (pin 2) terminal enables mechanical stability without electrical function.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in 24 V/48 V automotive supply rail clamping. |
| trr | 4 ns - Measured reverse recovery time; enables clean switching in pulse-width modulation (PWM) gate drivers up to 100 MHz. |
| IF | 215 mA - Continuous forward current rating; supports sustained logic-level signal steering in CAN/LIN bus interface protection. |
| IR @ VR=80 V | 0.5 µA - Low reverse leakage ensures minimal standby power loss in always-on vehicle modules. |
| Cd @ VR=0 V | 1.5 pF - Diode capacitance at zero bias; minimizes signal distortion in high-frequency data line termination. |
| VF @ IF=10 mA | 855 mV - Forward voltage drop; enables low-loss level shifting between 3.3 V and 5 V logic domains. |
| Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance on standard FR4; informs derating requirements for 125 °C ambient designs. |
Pinout & Package
Encapsulated in a standard SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch), the BAS16-QR uses a 3-terminal configuration with pin 2 internally not connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward current entry point; connects to higher-potential node in clamping or steering paths. |
| 2 | Not Connected (n.c.) | Mechanical support only; must remain unconnected in PCB layout to avoid parasitic coupling. |
| 3 | Cathode (K) | Forward current exit point; ties to reference or return path; used for cathode-grounded clamp configurations. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications per stress test standard; eliminates need for customer requalification in Tier-1 ECU designs. |
| trr ≤ 4 ns | Enables reliable high-frequency switching in USB 2.0 data line protection and LIN transceiver output stages. |
| Low Cd = 1.5 pF | Preserves signal integrity in 100 Mbps+ serial interfaces by minimizing capacitive loading on differential pairs. |
| VR = 100 V | Supports robust transient suppression in 24 V battery-supplied systems with load-dump spikes up to 87 V. |
| IF = 215 mA | Handles sustained current in LED indicator drive and microcontroller I/O protection without thermal runaway. |
Applications
| Automotive Body Control Module (BCM) | CAN Transceiver Protection |
|---|---|
Use Scenario: Clamping inductive kickback from door lock actuators and mirror motors during PWM switching. IC Role / Device Role: Fast-recovery flyback diode across relay coils and solenoid drivers. Use Value: Prevents MCU I/O damage from 100 V transients while maintaining <4 ns turn-off to avoid shoot-through in half-bridge drivers. |
Use Scenario: ESD and surge protection on CAN_H/CAN_L lines in junction box ECUs. IC Role / Device Role: Low-capacitance bidirectional clamp diode in TVS-assisted protection networks. Use Value: Adds <1.5 pF parasitic capacitance to preserve CAN FD signal rise/fall times while enabling 100 V standoff. |
| Industrial PLC Digital Input Stage | USB 2.0 Data Line Level Shifting |
Use Scenario: Signal conditioning of 24 V DC sensor inputs into 3.3 V microcontroller GPIOs. IC Role / Device Role: High-speed level translator and overvoltage limiter in optocoupler input circuits. Use Value: Delivers 855 mV VF at 10 mA to maintain noise margin while blocking reverse leakage below 0.5 µA at 24 V. |
Use Scenario: Bidirectional voltage translation between 3.3 V host controller and 5 V peripheral PHY layers. IC Role / Device Role: Passive forward-biased diode in resistor-diode level-shifter topology. Use Value: Enables <100 ps timing skew across D+ and D− lines due to matched trr and Cd characteristics. |
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 MMBD1203 | VRRM = 100 V, trr = 4 ns, but VF = 1.25 V @ IF = 150 mA - 400 mV higher than BAS16-QR at same current. | Higher forward drop increases power dissipation in high-duty-cycle PWM applications. | Select when higher surge tolerance (IFSM = 2 A) outweighs VF penalty in intermittent switching. |
| Diodes Incorporated BAV99W | Dual diode in SOT363; per-diode trr = 4 ns, but Cd = 2 pF - 0.5 pF higher than BAS16-QR. | Increased capacitance degrades signal integrity in >50 Mbps data lines. | Choose only when dual-channel integration reduces board area more than 0.5 pF capacitance cost. |
Compared with MMBD1203 and BAV99W, the BAS16-QR offers the lowest combined VF–Cd–trr tradeoff for single-diode automotive signal routing, making it optimal where thermal headroom, bandwidth, and leakage are simultaneously constrained.

FAQ
Is BAS16-QR pin-compatible with BAS16 or BAS21?
No. BAS16-QR uses SOT23 with pin 2 n.c., whereas BAS16 (SOT23) has pin 2 as cathode and BAS21 (SOT23) has pin 2 as anode. Swapping them causes incorrect polarity and circuit failure. Pin mapping must be verified per Table 2 in the 2021 datasheet.
What is the maximum allowable PCB temperature rise during reflow for BAS16-QR?
The device supports JEDEC J-STD-020-compliant reflow profiles with peak temperature ≤ 260 °C for ≤ 30 seconds. Its 150 °C Tj(max) and 500 K/W Rth(j-a) require board layout that limits junction temperature rise to ≤ 125 °C above ambient under full load.
Can BAS16-QR replace BAT54 in 5 V logic clamping applications?
Yes, but with tradeoffs: BAS16-QR has higher VRRM (100 V vs. 30 V) and lower Cd (1.5 pF vs. 10 pF), improving surge margin and speed, yet its VF is 855 mV @ 10 mA versus BAT54's 320 mV - increasing voltage drop in low-voltage rails.
Does BAS16-QR support wave soldering?
Yes. Nexperia provides dedicated wave soldering footprint (Fig. 9) with 1.4 mm pad width and 2.2 mm spacing. Recommended preheat ≤ 100 °C and contact time ≤ 3 seconds to avoid delamination or internal bond wire damage.
