Product details
Overview
BAV99S/ZLX from Nexperia is a quadruple high-speed switching diode array in SOT363 (SC-88) package, configured as two independent series-connected diode pairs for dual-channel clamping or polarity protection. It delivers trr ≤4 ns reverse recovery time, Cd ≤1.5 pF capacitance at 1 MHz/0 V, and supports 100 V repetitive peak reverse voltage per diode - enabling use in ESD-critical USB data lines and automotive CAN bus interface protection circuits.
For engineers reviewing the BAV99S/ZLX datasheet, BAV99S/ZLX pinout, BAV99S/ZLX application, or BAV99S/ZLX equivalent, key selection criteria include verified 4 ns trr performance under IF=10 mA → IR=10 mA switching, AEC-Q101 qualification for automotive environments, and precise 6-pin SOT363 terminal mapping for PCB layout validation.
Technical Context
The BAV99S integrates four discrete silicon epitaxial planar diodes in a single compact SOT363 package, with pins 1–2 and 4–5 forming two anode-cathode paths, while pins 3 and 6 serve as shared cathode/anode nodes for series configuration. This architecture enables dual-channel bidirectional clamping without external interconnects.
Its low 1.5 pF junction capacitance and sub-4 ns trr are achieved via optimized doping profiles and minimized carrier lifetime - critical for preserving signal integrity in >100 Mbps digital interfaces. Thermal resistance Rth(j-sp) = 260 K/W (measured at solder points 2, 3, 5, 6) ensures stable operation up to 150 °C junction temperature under pulsed loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | ≤4 ns - Enables reliable switching in 100+ Mbps digital signal paths without timing skew. |
| Junction Capacitance (Cd) | ≤1.5 pF at 1 MHz / 0 V - Minimizes signal loading on high-speed data lines like USB 2.0 or CAN FD. |
| Repetitive Peak Reverse Voltage (VRRM) | 100 V per diode - Supports robust overvoltage protection in 24 V automotive and industrial control systems. |
| Forward Current (IF) | 200 mA continuous - Sustains clamping duty cycles in transient-suppression applications without thermal derating. |
| Reverse Leakage (IR) | ≤0.5 μA at VR = 80 V - Ensures low standby power loss in battery-powered sensor nodes. |
| AEC-Q101 Qualified | Validated for automotive-grade reliability - required for engine control unit (ECU) and body electronics deployment. |

Applications
| USB 2.0 Data Line Protection | Automotive CAN Bus Interface |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD events up to ±15 kV per IEC 61000-4-2. IC Role / Device Role / Timing Role: Bidirectional clamping diode array providing low-capacitance path to VBUS and GND during transients. Use Value: 1.5 pF capacitance preserves signal rise/fall times; 4 ns trr prevents latch-up during fast ESD pulses. |
Use Scenario: Shielding CAN_H and CAN_L from load-dump surges and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Dual-series diode string clamping each bus line to battery and ground rails. Use Value: 100 V VRRM withstands 24 V system transients; AEC-Q101 rating ensures 15-year field reliability. |
| Industrial Sensor Signal Conditioning | Power Supply Input Polarity Protection |
Use Scenario: Guarding analog outputs of pressure/temperature sensors against miswiring and cable discharge. IC Role / Device Role / Timing Role: Low-leakage (≤0.5 μA) clamping diode pair limiting input voltage swing to safe ADC range. Use Value: 0.5 μA IR at 80 V prevents DC offset drift in precision 24-bit sigma-delta measurement chains. |
Use Scenario: Preventing damage from reverse-battery connection in 12 V/24 V embedded controllers. IC Role / Device Role / Timing Role: Series-connected diode pair acting as low-loss forward conduction path with minimal VF drop. Use Value: 855 mV VF at 10 mA limits power loss to <10 mW per channel - critical for thermally constrained enclosures. |
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 |
|---|---|---|---|
| BAV99W/SOT323 | Same die, dual-diode configuration in smaller 3-pin SOT323 package; no pin 4–6 terminals. | Limited to single-channel protection; lacks independent dual-path capability of BAV99S. | Select when board space is constrained and only one clamping path is required. |
| ESDR0514MUTAG | TVS-based solution with 5 V clamping voltage; higher capacitance (12 pF) but lower dynamic resistance. | Designed for ESD-only suppression (IEC 61000-4-2), not sustained overvoltage or polarity reversal. | Choose for pure ESD immunity where speed is secondary to clamping voltage precision. |
Compared with BAV99W/SOT323, BAV99S offers dual independent channels in one package; versus ESDR0514MUTAG, it provides superior high-frequency response and broader voltage handling but requires external biasing for active clamping.

FAQ
What is the maximum operating temperature for BAV99S/ZLX?
The BAV99S/ZLX has a maximum junction temperature (Tj) of 150 °C and operates across an ambient temperature range of −65 °C to +150 °C. Its thermal resistance from junction to solder point is 260 K/W, allowing sustained 200 mA forward current at 85 °C ambient when mounted on FR4 PCB with standard footprint and soldered at pins 2, 3, 5, and 6.
Is BAV99S/ZLX suitable for USB 3.0 applications?
No - BAV99S/ZLX is not recommended for USB 3.0 SuperSpeed (5 Gbps) due to its 1.5 pF capacitance causing measurable insertion loss above 1 GHz. It is validated for USB 2.0 (480 Mbps) and lower-speed interfaces such as CAN, RS-232, and I²C where bandwidth requirements remain below 200 MHz.
How does the dual-series configuration affect forward voltage drop?
In series mode (e.g., pins 1→3→2), forward conduction passes through two diodes, resulting in ~1.7 V total VF at 10 mA (2 × 855 mV). This is explicitly supported by the datasheet's VFR = 1.75 V specification under forward recovery test conditions, confirming predictable voltage doubling in cascaded operation.
Does BAV99S/ZLX require external biasing for clamping operation?
Yes - unlike TVS diodes, BAV99S/ZLX functions as a passive silicon diode array and requires explicit DC biasing to VCC and/or GND to establish clamping thresholds. For USB data line protection, it is typically used with pull-up/pull-down resistors to define the clamp voltage window relative to signal common-mode levels.
