Product details
Overview
BAW156Q-13-F from Diodes Incorporated is a dual low-leakage silicon switching diode in SOT23 package, rated for 85 V peak reverse voltage, 140 mA double-diode forward current, and 3.0 µs reverse recovery time. It serves as a signal-level clamping or steering diode in automotive sensor interfaces and ESD-protected I/O circuits.
For engineers reviewing the BAW156Q-13-F datasheet, BAW156Q-13-F pinout, BAW156Q-13-F application, or BAW156Q-13-F equivalent, key selection criteria include leakage current at high temperature (≤80 nA @ 75 V, +150°C), low forward voltage (1.1 V @ 50 mA), dual-element integration in SOT23, and AEC-Q101 qualification for under-hood use.
Technical Context
The BAW156Q-13-F integrates two independent silicon PN junction diodes in a single SOT23-3 package with common cathode configuration confirmed by internal schematic and top-view marking diagram. Its design targets low-capacitance (3 pF @ 0 V) and fast switching (trr ≤ 3.0 µs) for high-frequency signal routing.
It operates across –55°C to +150°C with thermal resistance of 500°C/W and supports automotive-grade reliability via IATF16949 manufacturing, PPAP capability, and AEC-Q101 stress testing including HTRB, HTGB, and TCT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - maximum repetitive reverse voltage before breakdown; enables use in 24 V automotive supply rail clamping |
| IF (dual) | 140 mA - continuous forward current per diode when both are active; supports multi-signal line protection |
| IR @ 75 V | 5.0 nA @ +25°C - ultra-low leakage preserves signal integrity in high-impedance sensor nodes |
| trr | 3.0 µs - reverse recovery time measured at IF = IR = 10 mA; suitable for <500 kHz switching |
| CT | 3 pF @ 0 V, 1 MHz - low junction capacitance minimizes signal distortion in RF-adjacent analog paths |
| TJ Range | –55°C to +150°C - extended temperature operation certified for engine control unit and transmission control modules |
Pinout & Package
Package: SOT23-3, surface-mount plastic package with matte tin-plated Alloy 42 leadframe, UL 94V-0 rated molding compound, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first signal path; routed to external trace requiring clamping or steering |
| 2 | Cathode (common) | Shared cathode connection; ties both diodes to reference rail (e.g., VCC or ground) |
| 3 | Anode of Diode 2 | Input node for second independent signal path; enables dual-line protection in compact layout |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain and body electronics per stress test requirements |
| Low IR at high temperature | 80 nA @ 75 V, +150°C - maintains signal fidelity in hot under-hood environments |
| Green construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); compliant with RoHS 3 and automotive environmental mandates |
| SOT23 footprint compatibility | Standard 3-pin SOT23 land pattern (C = 2.0 mm, X = 0.8 mm, Y = 0.9 mm) enables drop-in PCB reuse |
Applications
| Automotive Sensor Interface | Industrial Analog Input Protection |
|---|---|
Use Scenario: Protecting LIN bus transceiver inputs against load-dump-induced transients in door module ECUs. IC Role / Device Role / Timing Role: Dual-anode clamping diode shunting overvoltage to VBAT rail while preserving signal edge integrity. Use Value: 3 pF capacitance avoids signal rise-time degradation; 85 V VRRM withstands ISO 7637-2 Pulse 1a (–100 V). | Use Scenario: Guarding 0–10 V analog inputs on PLC I/O cards from field-wiring faults and ESD events. IC Role / Device Role / Timing Role: Low-leakage steering diode directing fault current away from precision ADC front-end. Use Value: 5 nA IR at +25°C prevents offset drift in 1 MΩ input impedance stages. |
| USB Port ESD Clamp | Low-Power IoT Signal Conditioning |
Use Scenario: Secondary ESD protection on USB 2.0 D+/D− lines behind primary TVS array in battery-powered medical monitors. IC Role / Device Role / Timing Role: Fast-recovery (3.0 µs trr) low-capacitance clamp limiting voltage overshoot during IEC 61000-4-2 contact discharge. Use Value: 3 pF CT ensures <1% signal attenuation at 480 MHz; dual configuration covers both data lines in one footprint. | Use Scenario: Biasing and signal routing in sub-1 µA sleep-mode environmental sensor nodes using MSP430 or nRF52 MCUs. IC Role / Device Role / Timing Role: Low-power signal steering diode enabling shared ADC channel multiplexing without leakage-induced measurement error. Use Value: 80 nA IR at +150°C ensures <0.1% gain error in thermistor-based temperature sensing at elevated ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-leakage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W-7-F | Higher IR (100 nA @ 75 V, +25°C); same SOT23-3, common cathode, but not AEC-Q101 qualified | Approved for commercial industrial use only; unsuitable for automotive PPAP submissions | Select when AEC-Q101 is not required and cost sensitivity outweighs leakage spec |
| NSR0230P2T5G | Lower VF (0.35 V @ 100 mA); Schottky architecture; 40 V VRRM; no high-temp IR spec published | Better efficiency in low-voltage bias networks; insufficient for 24 V system clamping | Prefer for 3.3 V/5 V logic-level steering where reverse voltage <40 V and leakage >100 nA is acceptable |
Compared with BAV99W-7-F and NSR0230P2T5G, the BAW156Q-13-F uniquely combines AEC-Q101 qualification, 85 V rating, and sub-10 nA room-temperature leakage-making it the only choice for high-reliability 12/24 V automotive signal conditioning where thermal stability and certification are mandatory.

FAQ
What is the polarity configuration of the BAW156Q-13-F?
The BAW156Q-13-F uses a common-cathode dual-diode configuration: Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2. This is confirmed by the internal schematic in DS30231 Rev. 11–2, Figure "Internal Schematic", and the top-view marking diagram showing K53 orientation.
Is the BAW156Q-13-F suitable for 48 V mild-hybrid automotive systems?
No. Its 85 V VRRM rating meets ISO 7637-2 Pulse 1a (–100 V) and Pulse 3b (±100 V) for 12 V/24 V systems but does not provide sufficient margin for 48 V nominal architectures where transients can exceed 120 V. For 48 V applications, Diodes recommends the BAW56Q-13-F (100 V VRRM) or BAV70Q-13-F (100 V).
Does the BAW156Q-13-F have a specified junction-to-case thermal resistance (RθJC)?
No. The datasheet specifies only RθJA = 500°C/W (on FR-4 board with recommended pad layout) and does not publish RθJC. Thermal modeling must rely on the provided RθJA value and JEDEC-standard board conditions; no case temperature derating curve is supplied.
Can the BAW156Q-13-F replace the BAW156-13-F in existing designs?
Yes-mechanically and electrically identical. The "Q" suffix denotes AEC-Q101 qualification and PPAP capability; all electrical specs, package dimensions, pinout, and marking are identical to the non-Q BAW156-13-F. No layout or firmware changes are needed for migration.
