Product details
Overview
BAS16THR 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 and digital logic interface circuits.
For engineers reviewing the BAS16THR datasheet, BAS16THR pinout, BAS16THR application, or BAS16THR equivalent, key selection criteria include trr ≤ 4 ns, AEC-Q101 qualification, 175 °C junction temperature rating, low leakage (≤ 0.5 µA at 80 V), and SOT23 footprint compatibility with high-density PCB layouts.
Technical Context
This diode operates as a unidirectional, silicon-based PN junction device optimized for rapid turn-off under transient conditions. Its 4 ns trr is measured under standardized 10 mA forward/10 mA reverse current conditions with 100 Ω load and 1 mA measurement threshold.
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 supports operation from −55 °C to +175 °C ambient, with reverse leakage rising predictably to 50 µA at 80 V and 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage before breakdown; defines safe blocking range in flyback or clamp circuits |
| IF | 215 mA - continuous forward current rating on standard FR4 PCB; sets upper limit for steady-state signal routing |
| trr | 4 ns - reverse recovery time under IF = IR = 10 mA; enables >100 MHz switching in digital isolators or level shifters |
| VF | 1.25 V at IF = 150 mA - forward voltage drop; determines conduction loss and self-heating in pulsed applications |
| IR | 0.5 µA at VR = 80 V, Tj = 25 °C - low leakage ensures minimal standby current in battery-backed systems |
| Cd | 1.5 pF at VR = 0 V, f = 1 MHz - low junction capacitance preserves signal integrity in RF-coupled or high-speed data lines |
Pinout & Package
Encapsulated in TO-236AB (SOT23) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, tin-plated copper leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward current entry point; connects to higher-potential node in rectification or clamping paths |
| 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; ties to ground or lower-potential rail in most configurations |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards |
| 175 °C junction rating | Enables deployment in engine control units and under-hood modules without derating at elevated ambient temperatures |
| Low trr (≤ 4 ns) | Minimizes switching losses and cross-conduction risk in synchronous rectifiers and high-frequency PWM drivers |
| Small SOT23 footprint | Supports automated placement and reflow on space-constrained boards while maintaining thermal accessibility via exposed cathode pad |
Applications

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 | VRRM = 100 V, trr = 4 ns, VF = 1.25 V at 150 mA - identical electrical specs but non-AEC-Q101 rated | Lacks automotive qualification; suitable for industrial/commercial designs where AEC compliance is not required | Select when cost sensitivity outweighs automotive qualification needs and thermal environment remains <150 °C |
| Diodes Incorporated BAV99W-7-F | Double diode array in SOT363; VRRM = 70 V, trr = 4 ns, VF = 1.25 V - lower voltage rating, dual configuration | Provides two matched diodes for differential or complementary signal paths; requires layout adjustment for single-diode use | Choose when dual-diode topology simplifies board routing or enables redundancy in safety-critical paths |
Compared with MMBD1201LT1G and BAV99W-7-F, BAS16THR uniquely combines AEC-Q101 qualification, 175 °C operation, and single-diode SOT23 simplicity-making it optimal for automotive ECU inputs, high-temp industrial sensors, and space-constrained RF detectors where reliability and thermal headroom are critical.

FAQ
Is BAS16THR pin-compatible with BAS16 or BAS21?
No. BAS16THR 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 configuration differ-direct substitution requires PCB redesign.
What is the maximum allowable soldering temperature profile for BAS16THR?
Nexperia specifies peak reflow temperature of 260 °C for 10 seconds max, with ramp-up rate ≤ 3 °C/s and ramp-down rate ≤ 6 °C/s. The device complies with JEDEC J-STD-020D moisture sensitivity level 1, eliminating pre-bake requirements for standard handling.
Does BAS16THR support bidirectional signal clamping?
No. As a unidirectional PN junction diode, BAS16THR conducts only from anode to cathode. For bidirectional clamping, two devices must be used in series opposition or a dedicated TVS diode like PTVS10VS1UR should be selected.
How does thermal resistance change when mounted on 2-layer vs. 4-layer PCB?
Rth(j-a) degrades from 500 K/W (FR4, single-side copper) to ~350 K/W on 2-layer PCB with internal ground plane, and further to ~280 K/W on 4-layer board with dedicated thermal vias to inner planes-enabling 30–40% higher continuous current capability at same ambient temperature.
