Product details
Overview
BAS56,235 from Nexperia is a dual high-speed switching diode in SOT143B package, featuring two isolated diodes with reverse recovery time ≤6 ns, repetitive peak reverse voltage of 60 V, and repetitive peak forward current of 600 mA - used for fast signal routing and clamping in automotive infotainment power management circuits.
For engineers reviewing the BAS56,235 datasheet, BAS56,235 pinout, BAS56,235 application, or BAS56,235 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values, and real-world use cases in surface-mounted high-frequency switching designs.
Technical Context
The BAS56,235 integrates two independent planar-technology diodes in a single SOT143B package, enabling compact dual-path switching without internal connection. Each diode supports 60 V reverse blocking and 600 mA repetitive peak forward current under defined thermal conditions.
Its 6 ns reverse recovery time (trr) and 2.5 pF junction capacitance at 0 V bias enable operation in >100 MHz signal paths. AEC-Q101 qualification confirms suitability for automotive ambient temperature ranges (−65 °C to +150 °C) and mechanical stress requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| trr | 6 ns - enables clean switching in 100+ MHz digital signal routing and RF detector applications |
| VRRM | 60 V - supports 24 V automotive supply rail transient suppression and logic-level clamping |
| IFRM | 600 mA - handles pulsed currents in ESD protection networks and level-shifting interfaces |
| Cd | 2.5 pF at 0 V - minimizes capacitive loading on high-speed data lines (e.g., USB 2.0, CAN FD) |
| Rth(j-a) | 500 K/W - defines thermal derating to 150 mW at 70 °C ambient on FR4 PCB |
| VF | 1 V at 200 mA - ensures low conduction loss in low-voltage biasing and signal steering circuits |
Pinout & Package
SOT143B plastic surface-mounted package (3.0 × 1.4 × 1.1 mm), 4-lead, small-outline transistor outline with gull-wing leads. Designed for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Output node for Diode 1; connects to load or reference ground in clamp configuration |
| 2 | Cathode (Diode 2) | Independent output node for Diode 2; allows separate signal path termination |
| 3 | Anode (Diode 2) | Input node for Diode 2; enables bidirectional signal routing when paired with Pin 2 |
| 4 | Anode (Diode 1) | Input node for Diode 1; used for input-side clamping or polarity-selective conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Isolated dual-diode structure | Enables independent control of two signal paths without shared cathode/anode nodes |
| Low trr (≤6 ns) | Reduces switching losses and prevents shoot-through in high-frequency PWM-driven circuits |
| Small SOT143B footprint | Occupies 4.2 mm² board area - ideal for space-constrained ADAS sensor modules and infotainment PCBs |
Applications
| Automotive Infotainment Power Sequencing | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Managing power-up order between MCU, display driver, and audio codec ICs in head unit designs. IC Role / Device Role / Timing Role: Dual-diode clamping network isolates reset signals and prevents backfeed during staggered rail activation. Use Value: Prevents latch-up in 3.3 V/1.8 V mixed-rail subsystems using only one SOT143B device instead of two discrete SOD-323 parts. |
Use Scenario: Protecting differential D+/D− lines from ESD transients in vehicle-mounted USB ports. IC Role / Device Role / Timing Role: High-speed bidirectional clamping diode pair shunts ±8 kV contact discharge energy to ground before IC damage occurs. Use Value: 6 ns trr ensures clamping action completes within first 10% of IEC 61000-4-2 waveform rise time (0.7–1 ns), preserving signal integrity. |
| Industrial Sensor Signal Conditioning | High-Frequency Oscillator Biasing |
Use Scenario: Level-shifting analog sensor outputs (e.g., thermistor bridges) into ADC inputs across isolated domains. IC Role / Device Role / Timing Role: Precision forward-biased diode pair provides matched 1 V drop for offset calibration and rail-to-rail signal translation. Use Value: Matched VF (±5%) and low Cd (2.5 pF) prevent phase shift in 10 kHz–1 MHz sensor excitation waveforms. |
Use Scenario: Providing stable DC bias to Colpitts oscillator tank circuits in wireless telemetry transmitters. IC Role / Device Role / Timing Role: Low-capacitance anode-cathode path sets precise DC operating point while minimizing Q-factor degradation. Use Value: 2.5 pF junction capacitance avoids detuning of 2.4 GHz ISM-band oscillators where <3 pF parasitic tolerance is required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS70-04,215 | Lower VRRM (70 V vs. 60 V), higher trr (100 ps vs. 6 ns), same SOT143B package | Better suited for ultra-high-frequency RF detection but less robust for 60 V automotive transients | Select when trr <100 ps is critical and reverse voltage stays below 50 V |
| MMBD7000LT1G | Higher IF (200 mA continuous vs. 150 mA), same trr (4 ns), SOT-23-3 package (single diode) | Requires two devices for dual-path function; lacks AEC-Q101 certification | Choose for cost-sensitive industrial designs where automotive qualification is not required |
Compared with BAS56,235, BAS70-04,215 trades reverse voltage margin for sub-nanosecond switching, while MMBD7000LT1G offers higher continuous current but requires double placement and lacks automotive qualification - making BAS56,235 optimal for space-constrained, AEC-Q101-compliant dual-path switching.

FAQ
What is the maximum junction temperature for BAS56,235?
The absolute maximum junction temperature (Tj) is 150 °C, validated per AEC-Q101 stress testing. At 25 °C ambient, the device dissipates up to 250 mW; derating begins at 1.5 mW/°C above 25 °C based on Rth(j-a) = 500 K/W on FR4 PCB.
Is BAS56,235 pin-compatible with BAS70-04,215?
Yes - both use SOT143B package with identical pin 1–4 assignment (cathode1, cathode2, anode2, anode1). However, BAS70-04,215 has different electrical characteristics (70 V VRRM, 100 ps trr) and is not AEC-Q101 qualified, so functional substitution requires circuit validation.
Can BAS56,235 be used in reverse-biased Zener mode?
No - the device is specified only as a switching diode with VR = 60 V and VRRM = 60 V. It lacks Zener breakdown characterization or guaranteed regulation performance; using it beyond 60 V risks irreversible avalanche failure.
What is the typical forward voltage at 100 mA?
Per Nexperia's datasheet Figure 1, VF is approximately 0.85 V at IF = 100 mA and Tj = 25 °C. This value increases to ~0.95 V at 150 °C junction temperature, reflecting the diode's positive temperature coefficient.
