Product details
Overview
BAS16THVL from Nexperia is a high-speed switching diode in SOT23 (TO-236AB) package, rated for 100 V repetitive peak reverse voltage, 215 mA forward current, and 4 ns reverse recovery time. It serves as a fast-switching signal path or clamping element in automotive power management, USB interface protection, and DC-DC converter freewheeling circuits.
For engineers reviewing the BAS16THVL datasheet, BAS16THVL pinout, BAS16THVL application, or BAS16THVL equivalent, key selection criteria include AEC-Q101 qualification, 175 °C junction temperature rating, low 1.5 pF capacitance at 0 V, and verified 0.5 µA reverse leakage at 80 V/25 °C.
Technical Context
The BAS16THVL operates as a single-junction silicon planar epitaxial diode optimized for minimal charge storage and rapid minority-carrier sweep-out. Its trr ≤ 4 ns is achieved under defined test conditions (IF = 10 mA, IR = 10 mA, RL = 100 Ω, IR(meas) = 1 mA), enabling use in >100 MHz switching nodes.
Thermal performance is defined by Rth(j-a) = 500 K/W on FR4 PCB and Rth(j-sp) = 330 K/W to cathode solder point. The device sustains continuous operation up to Tj = 175 °C and meets AEC-Q101 stress requirements for automotive underhood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum reverse voltage before breakdown; supports 48 V automotive bus transient suppression. |
| IF | 215 mA - Continuous forward current rating on standard FR4 PCB; sufficient for logic-level signal routing. |
| trr | 4 ns - Measured reverse recovery time; enables clean switching in 100+ MHz clock distribution paths. |
| VF @ 150 mA | 1.25 V - Forward voltage drop defining conduction loss in high-frequency rectification stages. |
| IR @ 80 V | 0.5 µA - Reverse leakage at elevated bias; ensures low standby power in always-on sensor interfaces. |
| Cd @ 0 V | 1.5 pF - Junction capacitance at zero bias; minimizes signal distortion in RF coupling and ESD clamp networks. |
Pinout & Package
Package: TO-236AB (SOT23), 3-terminal surface-mount plastic package with 1.9 mm lead pitch, 2.9 mm × 1.3 mm × 1.0 mm body dimensions and tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward current entry point; connects to higher-potential node in switching or clamping configuration. |
| 2 | Not Connected (n.c.) | Internally isolated terminal; must remain unconnected on PCB to avoid parasitic coupling or thermal stress. |
| 3 | Cathode (K) | Forward current exit and reverse voltage reference; soldered to ground or return path for thermal dissipation. |
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 use in high-frequency DC-DC converters operating above 500 kHz without significant switching loss penalty. |
| Tj max = 175 °C | Supports placement near heat-generating components (e.g., MOSFETs, inductors) in engine control units. |
| Low Cd = 1.5 pF | Reduces capacitive loading on high-speed digital lines, preserving signal integrity in USB 2.0 and CAN FD interfaces. |
| IFSM = 4 A (1 µs) | Withstands short-circuit transients in automotive load-dump protection circuits without failure. |
Applications
| Automotive Engine Control Unit (ECU) | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Clamping inductive kickback from solenoid drivers during PWM switching. IC Role / Device Role / Timing Role: Fast-recovery flyback diode providing low-inductance return path for stored coil energy. Use Value: 4 ns trr prevents voltage overshoot beyond 100 V rail, eliminating need for TVS supplementation in cost-sensitive designs. |
Use Scenario: ESD protection and signal integrity preservation on D+/D− differential pairs. IC Role / Device Role / Timing Role: Low-capacitance steering diode shunting transients to VBUS/GND while minimizing data eye degradation. Use Value: 1.5 pF capacitance avoids >10% rise-time degradation at 480 Mbps, meeting USB-IF compliance thresholds. |
| DC-DC Converter Freewheeling | Industrial Sensor Signal Conditioning |
Use Scenario: Synchronous rectification replacement in 12 V → 3.3 V buck converters for PLC I/O modules. IC Role / Device Role / Timing Role: High-speed switching diode conducting freewheel current during low-side FET off-time. Use Value: 1.25 V VF at 150 mA yields <190 mW conduction loss, enabling thermally constrained 2-layer PCB layouts. |
Use Scenario: Level-shifting and overvoltage clamping in 4–20 mA loop transmitter front-ends. IC Role / Device Role / Timing Role: Precision clamping diode limiting input voltage excursions to protect op-amp inputs. Use Value: 0.5 µA IR at 80 V ensures <40 nA error current injection into precision current-sense resistors. |
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 MMBD1203LT1G | trr = 3.5 ns (typ), VF = 1.2 V @ 150 mA, VRRM = 100 V, same SOT23 package | Slightly faster recovery but lower IF rating (150 mA vs. 215 mA); not AEC-Q101 qualified | Select when ultra-low trr dominates over automotive qualification and higher current handling. |
| Diodes Incorporated BAV199LT1G | trr = 4 ns (max), VF = 1.25 V @ 150 mA, VRRM = 100 V, dual-diode SOT363 package | Dual configuration increases board area; higher thermal resistance due to shared die; no AEC-Q101 certification | Choose only if dual-channel topology eliminates need for second discrete diode and space permits larger footprint. |
Compared with MMBD1203LT1G and BAV199LT1G, the BAS16THVL uniquely combines AEC-Q101 qualification, 215 mA IF rating, and 4 ns trr in a single-diode SOT23 package-making it the only option qualified for automotive underhood use without derating or secondary qualification effort.

FAQ
Is BAS16THVL pin-compatible with BAS16 or BAS21?
No. BAS16THVL uses SOT23 (TO-236AB) with Pin 2 unconnected, whereas BAS16 (SOT23) has Pin 2 as cathode and BAS21 (SOD-123) is a two-terminal package. Physical pinout and thermal pad layout differ; direct substitution requires PCB redesign.
What is the maximum allowable ambient temperature for continuous operation?
At Tamb = 175 °C, the device remains within safe operating limits only if power dissipation is reduced to zero per the derating curve. With Ptot = 300 mW at Tamb ≤ 25 °C and Rth(j-a) = 500 K/W, maximum continuous Tamb is 125 °C at 150 mW dissipation on standard FR4 PCB.
Does BAS16THVL support wave soldering?
Yes. Nexperia provides dedicated wave soldering footprint (Fig. 11) with 1.4 mm × 2.2 mm solder lands and 4.5 mm transport direction length. Recommended preheat 100–120 °C, peak temperature 260 °C for ≤ 5 s, and flux residue compatible with automotive cleanliness standards.
How does the n.c. pin affect PCB layout and thermal performance?
Pin 2 must remain unconnected on the PCB to prevent unintended thermal or electrical coupling. Its presence reduces effective copper area under the package; thermal modeling shows 8–10% higher junction temperature versus fully populated 3-pin SOT23 variants when using identical land patterns.
