Product details
Overview
BAV99S/ZLF from Nexperia is a quadruple high-speed switching diode array in SOT363 (SC-88) package, configured as two independent series-connected diode pairs. It delivers trr ≤4 ns reverse recovery time, Cd ≤1.5 pF capacitance at 1 MHz/0 V, and VR = 100 V peak reverse voltage - enabling fast signal routing and polarity protection in compact DC-DC converter feedback paths and USB port ESD clamping circuits.
For engineers reviewing the BAV99S/ZLF datasheet, BAV99S/ZLF pinout, BAV99S/ZLF application, or BAV99S/ZLF equivalent, key selection criteria include verified dual-series diode topology, AEC-Q101 qualification for automotive-grade reliability, low-leakage performance at 80 V reverse bias (IR ≤0.5 μA), and thermal resistance Rth(j-sp) = 260 K/W under standard FR4 mounting.
Technical Context
The BAV99S implements four discrete silicon epitaxial planar diodes arranged in two isolated series pairs (D1–D2 and D3–D4), sharing common terminals at pins 3 and 6 to enable compact dual-channel clamping or steering. Each diode exhibits VF = 855 mV at IF = 10 mA and IR = 30 nA at VR = 25 V, supporting low-loss signal-level switching.
Its SOT363 package supports high-density placement with 0.65 mm lead pitch and 1.3 mm × 2.2 mm footprint. Thermal design is validated per IEC 60134 limiting values, with Ptot = 250 mW at Tsp ≤85 °C and junction temperature rated to 150 °C - suitable for thermally constrained industrial control I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse voltage (VR) | 100 V - supports input rail protection up to 80 V DC without breakdown |
| Reverse recovery time (trr) | ≤4 ns - enables clean switching in >100 MHz digital signal routing and RF detector circuits |
| Diode capacitance (Cd) | ≤1.5 pF at 1 MHz/0 V - minimizes signal distortion in high-frequency analog switch and mixer applications |
| Forward voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in 3.3 V and 5 V logic-level clamp networks |
| Reverse leakage (IR) | ≤0.5 μA at VR = 80 V - maintains signal integrity in precision sensor front-ends and battery-monitoring paths |
| Peak forward current (IFSM) | 4 A for 1 μs - withstands transient surges in hot-swap controller and load-switch protection circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W/SOT323 | Dual-diode (not quadruple); same trr ≤4 ns and VR = 100 V, but smaller 3-pin SC-70 package | Limited to single-channel protection; lacks independent dual-series topology | Select when board space is more constrained than channel count, and only one clamping path is required |
| MMBD7000LT1G | Quadruple diode array in SOT23-6, but higher trr = 6 ns and VR = 70 V; not AEC-Q101 qualified | Lower voltage rating restricts use to 5 V/12 V systems; no automotive qualification | Choose for cost-sensitive consumer applications where 70 V rating and non-automotive grade are acceptable |
Compared with BAV99W and MMBD7000LT1G, the BAV99S/ZLF uniquely combines AEC-Q101 qualification, 100 V rating, quadruple dual-series architecture, and 4 ns trr - making it the only option for dual-channel automotive-grade clamping in space-constrained designs.

FAQ
What is the maximum continuous forward current per diode in the BAV99S/ZLF?
The BAV99S/ZLF supports a maximum continuous forward current of 200 mA per diode at Tamb ≤25 °C, as specified in Table 6 of the Nexperia datasheet Rev. 8. This rating assumes single-diode loading and derates linearly above 25 °C ambient, reaching zero at 150 °C junction temperature.
Does the BAV99S/ZLF meet automotive reliability standards?
Yes - the BAV99S/ZLF is fully qualified to AEC-Q101 for stress testing of discrete semiconductors, including high-temperature operating life, temperature cycling, and ESD robustness. Its qualification is documented in Section 8.1 of the official Nexperia product data sheet.
How is the dual-series configuration implemented in the SOT363 package?
The BAV99S/ZLF integrates four diodes in two independent series pairs: D1–D2 shares pins 1–3–2, and D3–D4 shares pins 4–6–5. Pin 3 is the cathode of D1 and anode of D2; pin 6 is the cathode of D3 and anode of D4 - enabling true dual-channel series clamping without external interconnects.
Can the BAV99S/ZLF be used for bidirectional ESD protection on a single signal line?
Yes - when biased with appropriate pull-up/pull-down resistors, the series-connected diodes (e.g., D1–D2 between pins 1–2 via pin 3) form a low-capacitance bidirectional clamp to VCC and GND. Its 1.5 pF capacitance and 4 ns trr ensure minimal signal degradation in high-speed interfaces like USB 2.0.
