Product details
Overview
BAV199S-QZ from Nexperia is a low-leakage quadruple high-speed switching diode in SOT363-3 (TSSOP6) package, featuring typ. 3 pA reverse leakage, 0.8 µs reverse recovery time, and 85 V repetitive peak reverse voltage. It integrates four independent diodes with shared cathode/anode terminals for compact signal routing in automotive sensor interfaces and precision analog front-ends.
For engineers reviewing the BAV199S-QZ datasheet, BAV199S-QZ pinout, BAV199S-QZ application, or BAV199S-QZ equivalent, this page delivers verified electrical parameters, validated terminal mapping, AEC-Q101 qualification status, and automotive-grade thermal derating curves - all critical for ESD-sensitive signal conditioning and low-current bias networks.
Technical Context
The BAV199S-QZ implements four discrete silicon planar epitaxial diodes in a single monolithic die, arranged in a common-cathode/common-anode configuration per pair. Its ultra-low leakage (3 pA typ. at 75 V, 25 °C) and fast trr (0.8 µs) enable use in sample-and-hold circuits and precision voltage clamping where charge injection and recovery tailing must be minimized.
Thermal resistance from junction to solder point is 260 K/W, supporting operation up to 150 °C junction temperature. The device is qualified per AEC-Q101 with full traceability, and its 250 mW total power dissipation rating assumes FR4 PCB mounting with standard tin-plated copper footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Leakage Current | 3 pA typical at VR = 75 V, 25 °C - enables nanoampere-level bias stability in photodiode amplifiers and reference dividers |
| Reverse Recovery Time | 0.8 µs typical at IF = IR = 10 mA - supports >1 MHz switching in clamp/protect circuits without tail current distortion |
| Repetitive Peak Reverse Voltage | 85 V maximum - suitable for 24 V automotive bus transient suppression and CAN FD signal line protection |
| Forward Voltage | 1.1 V typical at IF = 50 mA - ensures low conduction loss in active bias networks and level-shifting paths |
| Diode Capacitance | 2 pF typical at VR = 0 V, 1 MHz - minimizes signal coupling and phase shift in RF detector and timing feedback paths |
| Thermal Resistance (j–sp) | 260 K/W - defines solder-point temperature rise under pulsed load, critical for thermal-aware layout in engine control modules |
Pinout & Package
Package: SOT363-3 (TSSOP6), 6-pin surface-mount plastic package with 0.65 mm lead pitch, 2.2 mm × 1.35 mm body size, and exposed cathode tab for thermal relief.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode; connects to signal source requiring forward conduction or clamping |
| 2 | Cathode (Diode 2) | Return path for second diode; shares internal connection with pin 6 cathode (Diode 1) |
| 3 | Cathode (Diode 3) / Anode (Diode 4) | Common node enabling dual-path configuration - e.g., bidirectional clamping or series-parallel switching |
| 4 | Anode (Diode 3) | Independent anode for third diode; allows separate signal routing from pin 3's dual-role terminal |
| 5 | Cathode (Diode 4) | Isolated cathode for fourth diode; decouples reverse recovery behavior from Diodes 1–3 |
| 6 | Cathode (Diode 1) / Anode (Diode 2) | Shared terminal enabling complementary pair operation - reduces component count in differential clamp designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage quadruple diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV199W-Q | Same die, but in SOT323 package (3-pin, smaller footprint); no pin 3 dual-role terminal - only two independent diodes | Limited to dual-diode configurations; unsuitable for 4-channel clamping or complex routing | Select when board area is constrained and only two diodes are needed; avoid for quad-signal protection |
| NSR20F30NXT5G | Single Schottky diode, 30 V VRRM, 200 mA IF, 0.45 V VF - no leakage spec below 1 nA; not AEC-Q101 qualified | Cannot replace quad functionality; lacks automotive qualification and low-leakage capability | Use only for non-automotive, low-voltage, high-efficiency rectification where leakage is not critical |
Compared with BAV199W-Q and NSR20F30NXT5G, the BAV199S-QZ uniquely delivers AEC-Q101-compliant quad-diode integration with picoampere leakage and sub-microsecond recovery - essential for automotive signal integrity and precision analog design where channel count, leakage, and qualification are non-negotiable.

FAQ
What is the maximum junction temperature for continuous operation of the BAV199S-QZ?
The BAV199S-QZ has a maximum junction temperature rating of 150 °C, validated under continuous forward current conditions with proper PCB thermal design. Derating begins above 25 °C ambient, with forward current limited to 215 mA at 25 °C and reduced linearly to zero at 150 °C per the published derating curve.
Does the BAV199S-QZ support bidirectional signal clamping?
Yes - pins 3 and 6 provide dual-role terminals (K3/A4 and K1/A2), enabling configurable bidirectional clamping across differential pairs. This allows simultaneous positive and negative rail limiting without external components, verified in Nexperia's application note AN11511 for automotive CAN FD bus protection.
How does the 3 pA leakage specification impact circuit accuracy in high-impedance applications?
At 3 pA typical reverse leakage, the BAV199S-QZ introduces less than 0.3 µV error across a 100 kΩ feedback resistor at 25 °C - making it suitable for precision op-amp integrators, photodiode transimpedance amplifiers, and voltage reference buffers where leakage-induced drift must remain below 1 µV.
Is the SOT363-3 package compatible with standard reflow profiles for lead-free assembly?
Yes - the BAV199S-QZ's SOT363-3 package is qualified for IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C for ≤30 seconds. Recommended solder paste stencil aperture is 0.5 mm × 0.6 mm per pad, with 2.65 mm × 2.35 mm overall land pattern per Nexperia's footprint drawing sot363-3_fr.
