Product details
Overview
BAW56S/DG/B2,135 from Nexperia is a dual high-speed switching diode in SOT23 package with common anode configuration, 90 V reverse voltage rating, ≤4 ns reverse recovery time, and ≤2 pF junction capacitance - used in high-frequency signal routing and clamping circuits in telecom line interface and USB port protection.
For engineers reviewing the BAW56S/DG/B2,135 datasheet, BAW56S/DG/B2,135 pinout, BAW56S/DG/B2,135 application, or BAW56S/DG/B2,135 equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, real-world switching use cases, and confirmed alternative diodes for fast-switching dual-diode topologies.
Technical Context
The BAW56S/DG/B2,135 integrates two independent silicon switching diodes sharing a common anode terminal, enabling compact dual-path clamping or steering without discrete pairing. Its ≤4 ns trr and ≤2 pF Cd support operation up to 100 MHz in RF detector and data-line transient suppression.
Thermal resistance of 360 K/W (junction-to-solder point) and 500 K/W (junction-to-ambient) confirms suitability for FR4 PCBs with standard copper foil, while 250 mW total power dissipation at Tamb ≤ 25 °C defines its continuous-duty envelope under pulsed forward current conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports DC bias and transient clamping in 48 V telecom and 24 V industrial bus lines |
| Reverse Recovery Time (trr) | ≤4 ns - enables clean switching in >100 MHz clock distribution and high-speed data line protection |
| Junction Capacitance (Cd) | ≤2 pF at 0 V - minimizes signal loading in RF front-end matching networks and antenna switch paths |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in low-power logic-level clamping applications |
| Reverse Leakage (IR) | 0.5 µA at 80 V, 25 °C - maintains high impedance isolation in standby and sleep-mode signal paths |
| Total Power Dissipation (Ptot) | 250 mW - sets thermal limit for continuous operation on standard FR4 PCB with single-sided copper |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, optimized for reflow soldering per IPC-7095.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Provides dedicated cathode path for first diode in dual-common-anode configuration |
| 2 | K2 (cathode of diode 2) | Enables independent cathode routing for second diode - critical for differential signal clamping |
| 3 | CA (common anode) | Shared anode node simplifies PCB layout for bidirectional ESD protection and level translation |
Key Features
| Feature | Design Value |
|---|---|
| Dual diode with common anode | Reduces component count and board area vs. two discrete diodes in rail-to-rail clamp designs |
| ≤4 ns reverse recovery time | Prevents switching-induced ringing in 50 Ω transmission lines and high-speed digital I/O protection |
| ≤2 pF junction capacitance | Maintains signal integrity in USB 2.0 and HDMI DDC channel protection without bandwidth degradation |
| 90 V peak reverse voltage | Withstands surge transients per IEC 61000-4-5 Level 3 (1 kV) when combined with TVS devices |
Applications
| USB 2.0 Data Line Protection | RS-485 Receiver Input Clamping |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD and cable-induced transients in portable USB peripherals. IC Role / Device Role / Timing Role: Dual-cathode clamping diode referenced to VCC and GND rails via common anode connection. Use Value: ≤2 pF capacitance avoids signal rise-time degradation; ≤4 ns trr prevents false triggering during hot-plug detection pulses. |
Use Scenario: Limiting input voltage excursions at RS-485 receiver inputs exposed to field wiring surges. IC Role / Device Role / Timing Role: Fast-switching clamp between differential inputs and supply rails using shared anode architecture. Use Value: 90 V VR withstands induced transients up to ±70 V; low leakage preserves receiver common-mode range accuracy. |
| RF Detector Diode Pair | Logic-Level Signal Steering |
Use Scenario: Quadrature demodulator front-end requiring matched dual diodes for phase-sensitive rectification. IC Role / Device Role / Timing Role: Two matched silicon diodes sharing thermal environment and anode reference for amplitude consistency. Use Value: Matched trr and Cd ensure <1° phase error across 1–100 MHz; common anode simplifies bias network. |
Use Scenario: Selecting between two 3.3 V logic sources feeding a single microcontroller input with pull-up. IC Role / Device Role / Timing Role: OR-ing diode pair with common anode tied to MCU input, cathodes to source signals. Use Value: 855 mV VF at 10 mA ensures reliable logic-high propagation; low capacitance avoids timing skew on 20 MHz control signals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99,215 | Same SOT23 package, identical pinout (K1/K2/CA), but higher typical trr = 4 ns (same max), same VR = 70 V (lower than BAW56's 90 V) | Lower reverse voltage limits use in 48 V systems; otherwise functionally interchangeable in 3.3 V/5 V logic clamping | Select when 70 V rating suffices and cost optimization is prioritized over 90 V margin |
| MMBD7000LT1G | Identical 90 V VR, but trr = 6 ns (max), Cd = 2.5 pF (max), and VF = 1.25 V at 150 mA (higher conduction loss) | Higher trr and Cd reduce suitability for >50 MHz signal paths; better for lower-frequency power rail clamping | Choose where thermal robustness (1 A IFSM) outweighs speed requirements in industrial control I/O modules |
Compared with BAV99,215 and MMBD7000LT1G, the BAW56S/DG/B2,135 delivers superior 90 V reverse margin and lowest capacitance among SOT23 dual diodes - making it optimal for high-frequency telecom and USB 2.0 protection where signal fidelity and transient headroom are jointly constrained.

FAQ
What is the maximum repetitive peak reverse voltage for BAW56S/DG/B2,135?
The maximum repetitive peak reverse voltage (VRRM) is 90 V, as defined in the Absolute Maximum Ratings table. This value applies per diode under continuous operation and aligns with IEC 60134 standards. It is not derated for temperature in the published specification, and operation above this voltage risks permanent device failure.
Is BAW56S/DG/B2,135 suitable for automotive applications?
No - the BAW56S/DG/B2,135 is explicitly designated as non-automotive qualified per Nexperia's revision history (v.7, October 2022). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, Nexperia recommends the BAW56-Q variant, which undergoes full automotive qualification testing.
How does the common anode configuration affect circuit layout?
The common anode (pin 3) simplifies PCB routing by consolidating the positive-side connection for both diodes, reducing trace count and minimizing parasitic inductance in high-speed clamp networks. It requires external connection to VCC or another reference potential, while cathodes (pins 1 and 2) route independently to protected nodes - ideal for bidirectional signal line protection.
What is the thermal resistance from junction to solder point (Rth(j-sp)) for this device?
The thermal resistance from junction to solder point is 360 K/W, measured on an FR4 PCB with single-sided copper, tin-plated finish, and standard SOT23 footprint. This value assumes proper solder joint formation and is used to calculate junction temperature rise under pulsed or continuous power dissipation conditions.
