Product details
Overview
BAS116QAZ from Nexperia is a single low-leakage switching diode in a DFN1010D-3 (SOT1215) package, rated for 85 V repetitive peak reverse voltage, 300 mA forward current, and delivering 0.8 µs reverse recovery time with only 3 pA leakage at 75 V. It serves as a precision signal-path switch in automotive sensor interfaces and low-power analog front-ends where minimal reverse current and fast turn-off are critical.
For engineers reviewing the BAS116QAZ datasheet, BAS116QAZ pinout, BAS116QAZ application, or BAS116QAZ equivalent, key selection criteria include ultra-low IR (3 pA), AEC-Q101 qualification, 2 pF junction capacitance, 0.37 mm profile for space-constrained layouts, and dual cathode terminals enabling robust PCB thermal anchoring.
Technical Context
This diode operates as a unidirectional signal switch with anode–cathode conduction path and two physically separate cathode terminals (pins 3 and 4) sharing the same electrical node. Its low trr (0.8 µs typ.) and Cd (2 pF) support high-frequency sampling and RF coupling isolation in mixed-signal systems.
The DFN1010D-3 package integrates solderable side pads and a cathode thermal pad, achieving Rth(j-sp) = 265 K/W and Rth(j-a) = 410 K/W on FR4 - enabling stable operation up to 150 °C junction temperature while maintaining <5 nA leakage across automotive ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - supports reverse blocking in 24 V automotive supply rails with 3.5× safety margin |
| IR @ 75 V | 3 pA typ. - ensures negligible leakage in high-impedance bias networks and precision reference dividers |
| trr | 0.8 µs typ. - enables clean switching in 1 MHz sample-and-hold and multiplexer control paths |
| Cd | 2 pF @ 0 V - minimizes capacitive loading on high-Z sensor outputs and clock distribution nodes |
| VF @ 150 mA | 1.25 V - delivers low forward drop for efficient signal clamping without excessive power dissipation |
| Tj max | 150 °C - meets under-hood automotive temperature requirements per AEC-Q101 stress testing |
| Package | DFN1010D-3 (SOT1215) - 1.1 × 1.0 × 0.37 mm footprint with side-wettable flanks for AOI-compatible reflow |
Pinout & Package
DFN1010D-3 (SOT1215) is a 4-terminal leadless plastic package with visible side pads, 0.37 mm height, and dual cathode terminals for enhanced thermal and mechanical reliability. Pin 2 is internally not connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Forward current entry point; connects to input signal or supply rail |
| 2 | Not connected | No internal bond wire; must be left floating or grounded per layout best practice |
| 3 | Cathode | Primary return path; electrically identical to pin 4; used for signal routing |
| 4 | Cathode | Secondary return path; provides redundant solder joint and thermal conduction to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, HTRB, and ESD per JESD22 standards |
| Ultra-low IR | 3 pA typical reverse leakage at 75 V enables >100 GΩ effective impedance in bias networks |
| Dual cathode terminals | Pins 3 and 4 reduce thermal resistance by 35% vs. single-cathode equivalents and improve solder joint inspection yield |
| AOI-compatible side pads | Visible copper sidewalls allow automated optical verification of solder fillet formation and coplanarity |
| Thermal-enhanced DFN | 0.37 mm height and exposed cathode pad achieve 265 K/W junction-to-solder-point resistance on 1 cm² copper |
Applications
| Automotive Cabin Sensors | High-Voltage Signal Clamping |
|---|---|
Use Scenario: Voltage-level translation and overvoltage protection in MEMS pressure sensor signal chains within HVAC control modules. IC Role / Device Role / Timing Role: Low-leakage clamp diode placed between sensor output and ADC input to limit transients without loading the high-Z source. Use Value: 3 pA IR prevents DC offset drift in 10 MΩ feedback networks; 2 pF capacitance avoids phase shift in 100 kHz sensor bandwidth. | Use Scenario: Input protection for industrial PLC analog inputs handling ±10 V signals exposed to field wiring surges. IC Role / Device Role / Timing Role: Fast-recovery series switch isolating fault currents during transient events while preserving signal integrity. Use Value: 0.8 µs trr limits glitch duration during surge clipping; 85 V VRRM accommodates 48 V system derating with margin. |
| Low-Power IoT Sensor Nodes | RF Signal Path Isolation |
Use Scenario: Power domain isolation between coin-cell-supplied microcontroller and wake-up interrupt line driven by external motion detector. IC Role / Device Role / Timing Role: Reverse-biased leakage barrier preventing battery drain through pull-up resistors when MCU is in deep sleep. Use Value: Sub-picoampere IR extends 10-year battery life by eliminating µA-scale standby leakage paths. | Use Scenario: Transmit/receive antenna switching in sub-GHz ISM band wireless modules using PIN diode replacement topology. IC Role / Device Role / Timing Role: Low-capacitance series switch controlling RF path continuity with minimal insertion loss. Use Value: 2 pF Cd yields <0.1 dB insertion loss at 868 MHz; 1.25 V VF allows drive from 3.3 V GPIO without level-shifting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS16L,115 | Higher IR (100 nA @ 75 V), larger SOD-323 package (1.7 × 1.3 mm), no AEC-Q101 qualification | Suitable for consumer-grade general-purpose switching but not automotive or precision biasing | Select when cost sensitivity outweighs leakage and qualification requirements |
| PMEG3010CEH,115 | Lower VRRM (30 V), Schottky architecture (VF = 0.35 V), higher Cd (35 pF), AEC-Q101 qualified | Better for low-VF power rectification, unsuitable for high-voltage reverse blocking or low-Cd RF paths | Select only for 5–12 V systems requiring ultra-low forward drop, not for 24/48 V or high-frequency signal routing |
Compared with BAS116QAZ, BAS16L offers lower cost but sacrifices 33× higher leakage and automotive qualification; PMEG3010CEH trades 85 V blocking and 2 pF capacitance for 0.35 V VF - making it incompatible with high-voltage or RF-sensitive designs despite shared AEC-Q101 status.

FAQ
What does the 'QAZ' suffix indicate in BAS116QAZ?
The 'QAZ' suffix denotes Nexperia's automotive-grade variant: 'Q' confirms AEC-Q101 qualification, 'A' indicates DFN1010D-3 (SOT1215) packaging, and 'Z' is the device-specific marking code laser-etched on the top surface. This distinguishes it from industrial versions like BAS116QA (no 'Z') and confirms full compliance with automotive stress test requirements.
Why does BAS116QAZ have four terminals but only three electrical nodes?
Pin 2 is internally not connected (n.c.), while pins 3 and 4 are both bonded to the same cathode die attach pad. This dual-cathode configuration improves thermal conduction to the PCB and provides redundancy for solder joint reliability - critical for automotive vibration environments - without altering electrical functionality.
Can BAS116QAZ replace BAS216 in existing designs?
No - BAS216 is a dual-diode array in SOT363 with different pinout, 100 V VRRM, and 5 nA IR. BAS116QAZ is a single-diode DFN with 85 V rating and 3 pA IR. Direct substitution would require PCB layout revision and validation of leakage impact on bias networks due to differing capacitance (2 pF vs. 4 pF) and thermal behavior.
Is the DFN1010D-3 package compatible with standard reflow profiles?
Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020D.2 lead-free reflow profiles (peak 260 °C, 20–40 s above 217 °C). The side-wettable flanks and 0.37 mm height ensure reliable solder joint formation and AOI detectability without requiring custom stencil apertures or underfill.
