Product details
Overview
BAW56S from Nexperia is a dual-common-anode high-speed switching diode array in SOT363-3 (TSSOP6) package, rated for 90 V reverse voltage, 4 ns reverse recovery time, and 2 pF capacitance per diode-designed for compact, high-frequency signal routing in RF front-ends and digital logic clamping.
For engineers reviewing the BAW56S datasheet, BAW56S pinout, BAW56S application, or BAW56S equivalent, this page delivers verified electrical parameters, validated dual-diode topology, thermal resistance (255 K/W), junction temperature limit (150 °C), and real-world switching performance under pulsed IF = 10 mA / IR = 10 mA conditions.
Technical Context
The BAW56S integrates four diodes in a single TSSOP6 package with two independent common-anode pairs: pins 1–2–6 form one dual-cathode/common-anode pair (D1/D2), and pins 3–4–5 form another (D3/D4). This configuration enables bidirectional clamping or dual-path signal steering without external interconnects.
Its 4 ns trr and ≤2 pF Cd support operation beyond 100 MHz in high-speed data lines, while the 0.5 µA IR at VR = 80 V ensures low standby leakage in battery-sensitive circuits. The device operates up to 150 °C junction temperature and dissipates 350 mW at Ts = 60 °C on FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports rail-to-rail clamping in 24 V industrial I/O and 48 V telecom interfaces |
| Reverse Recovery Time (trr) | 4 ns - enables clean edge transitions in >100 MHz clock distribution and USB 2.0 signal integrity |
| Diode Capacitance (Cd) | 2 pF at VR = 0 V - minimizes signal loading on high-Z analog inputs and RF detector nodes |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in logic-level translation and ESD protection paths |
| Reverse Current (IR) | 0.5 µA at VR = 80 V, 25 °C - maintains low quiescent power in always-on sensor interface circuits |
| Junction-to-Solder Point Rth | 255 K/W - defines thermal path for board-level reliability modeling in sealed enclosures |

Use Scenario: Protecting D+ and D− lines against ESD transients and overvoltage during hot-plug events in portable devices. IC Role / Device Role / Timing Role: High-speed clamping diode array providing bidirectional current shunting before transients reach the USB transceiver IC. Use Value: 4 ns trr prevents transient energy from propagating into the PHY; 2 pF Cd avoids signal distortion at 480 Mbps full-speed signaling. |
Use Scenario: Limiting RF input swing to prevent saturation of logarithmic amplifier inputs in cellular front-end modules. IC Role / Device Role / Timing Role: Fast-response voltage limiter placed directly at detector input to clip peaks above VCC + 0.7 V. Use Value: Dual common-anode structure allows simultaneous clamping of both RF envelope and DC bias rails using shared anode connections. |
| Digital Logic Level Translation | Industrial I/O Signal Conditioning |
|
Use Scenario: Translating 3.3 V CMOS logic outputs to 5 V tolerant inputs in mixed-voltage microcontroller systems. IC Role / Device Role / Timing Role: Passive level-shifting diode network leveraging forward conduction and reverse isolation characteristics. Use Value: 855 mV VF at 10 mA ensures minimal voltage drop across translation path; low Cd preserves rise/fall times <1 ns. |
Use Scenario: Isolating PLC analog input channels from field-wiring surge events and ground-loop noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp in multi-stage protection circuit, positioned ahead of TVS and series impedance. Use Value: 90 V VR rating matches industrial 24 V/48 V supply rails; 0.5 µA IR prevents DC offset drift in 24-bit sigma-delta ADC front-ends. |
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 |
|---|---|---|---|
| BAV99S,135 | Same SOT363-3 package but single common-anode dual-diode (not dual-pair); trr = 4 ns, Cd = 2 pF, VR = 70 V | Limited to one clamping function per package; insufficient for independent dual-path protection | Select when only one dual-diode channel is needed and 70 V rating suffices |
| CMKD2004TR | SC-74 package (SOT-26); dual common-cathode configuration; trr = 3.5 ns, VR = 80 V, Cd = 1.8 pF | Requires layout revision due to different pinout and cathode-common topology; not drop-in | Choose for marginally faster trr where board redesign is acceptable and cathode-referenced design is preferred |
Compared with BAV99S,135 and CMKD2004TR, the BAW56S uniquely provides two electrically isolated common-anode diode pairs in one SOT363-3 footprint-enabling true dual-channel clamping without inter-channel coupling or PCB trace routing compromises.

FAQ
What is the maximum continuous forward current per diode in the BAW56S?
The BAW56S supports 250 mA per diode at Ts = 60 °C, with a total device limit of 100 mA due to thermal constraints in the SOT363-3 package. Derating is required above 60 °C ambient; at 100 °C, the per-diode limit drops to approximately 120 mA based on thermal resistance (255 K/W) and 150 °C Tj max.
Can the BAW56S be used for bidirectional ESD protection on differential pairs?
Yes-the dual common-anode architecture allows each diode pair (Pins 1/2/6 and Pins 3/4/5) to clamp one side of a differential signal independently. When biased to VCC, it provides symmetrical ±(VCC + 0.85 V) clamping with sub-ns response, meeting IEC 61000-4-2 Level 4 requirements when combined with series impedance.
Is the BAW56S automotive qualified?
No-the BAW56S is not AEC-Q101 qualified and lacks automotive-specific testing or qualification documentation. It is rated for industrial temperature range (−65 °C to +150 °C), but Nexperia explicitly states non-automotive qualification unless otherwise specified in the datasheet, and no such statement appears for this part.
How does the thermal resistance of 255 K/W translate to practical PCB layout?
This value assumes mounting on FR4 with single-sided copper, tin-plated, and standard SOT363-3 footprint. To achieve rated 350 mW dissipation, ensure ≥10 mm² of 1 oz copper pour connected to all six leads, avoid thermal isolation cuts, and maintain ≥2 mm clearance from other heat sources. Without enhanced copper, derate power by 40%.
