Product details
Overview
BAW156VL from Nexperia is a low-leakage, medium-speed switching double diode in common-anode configuration, housed in an SOT23 surface-mount package. It delivers typ. 3 pA reverse leakage at 75 V, 0.8 µs reverse recovery time, and supports 500 mA repetitive peak forward current - enabling precision signal routing and voltage clamping in automotive sensor interfaces and low-power analog front-ends.
For engineers reviewing the BAW156VL datasheet, BAW156VL pinout, BAW156VL application, or BAW156VL equivalent, this dual diode is selected for AEC-Q101-compliant designs requiring ultra-low IR, fast transient response, and space-constrained SMT layouts with shared-anode topology.
Technical Context
The BAW156VL integrates two epitaxial silicon diodes sharing a single anode terminal (Pin 3), forming a compact dual-cathode structure optimized for bidirectional clamping and polarity-selective signal steering. Its low junction capacitance (3 pF at 0 V) and tight trr distribution (0.8–3 µs) support clean high-frequency waveform handling in 10–100 MHz sensing paths.
Thermal performance is defined by Rth(j-a) = 500 K/W on FR4 PCB and Rth(j-sp) = 360 K/W to solder point, with maximum junction temperature rated at 150 °C and ambient operating range from −55 °C to +150 °C - confirming suitability for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse leakage current | Typ. 3 pA at VR = 75 V, Tj = 25 °C - enables nanoamp-level bias stability in precision reference and leakage-sensitive sensor circuits. |
| Reverse recovery time | Typ. 0.8 µs (IF = 10 mA, IR = 10 mA, IR(meas) = 1 mA) - ensures minimal switching distortion in 1–2 MHz signal conditioning stages. |
| Repetitive peak reverse voltage | 85 V - supports robust operation across 12 V/24 V automotive supply rails with margin against load-dump transients. |
| Repetitive peak forward current | 500 mA per diode - accommodates pulsed ESD protection and moderate-current clamp duty without derating. |
| Forward voltage | 1.25 V at IF = 150 mA, Tj = 25 °C - balances conduction loss and thermal rise in continuous-duty clamping applications. |
| Diode capacitance | 3 pF at VR = 0 V, f = 1 MHz - preserves signal integrity in RF-adjacent analog inputs and high-speed data line protection. |
Pinout & Package
SOT23 plastic surface-mount package (3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body); JEDEC TO-236AB compliant; marked "JZ%" (site code placeholder).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Provides dedicated cathode path for first diode; used for independent signal clamping or polarity selection. |
| 2 | K2 (cathode of diode 2) | Independent cathode for second diode; enables dual-path routing (e.g., positive/negative rail clamping). |
| 3 | CA (common anode) | Shared anode node - simplifies PCB layout for bidirectional protection and reduces trace count in differential interface designs. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - eliminates requalification effort for Tier 1 ECUs. |
| Ultra-low reverse leakage | 3 pA typical at 75 V reverse bias - maintains accuracy in high-impedance feedback networks and battery-monitoring dividers. |
| Common-anode dual-diode topology | Single-package integration of two matched diodes sharing one anode - reduces board area by ~40% vs. discrete SOT23 singles. |
| Fast reverse recovery | 0.8 µs typical trr - minimizes tail current and cross-conduction risk in synchronous rectifier and snubber circuits. |
Applications
| Automotive Sensor Signal Conditioning | Low-Power Analog Front-End Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAW56VL | Higher leakage (typ. 5 nA at 75 V), slower trr (typ. 4 µs), same SOT23 package and CA topology. | Not AEC-Q101 qualified; suitable only for non-automotive consumer or industrial use. | Select when cost sensitivity outweighs leakage and speed requirements, and automotive qualification is unnecessary. |
| MMBD7000LT1G | Lower VRRM (100 V), higher VF (1.25 V @ 100 mA), no AEC-Q101 certification, but offers lower trr (4 ns) and tighter matching. | Designed for high-speed digital logic clamping, not analog signal integrity or automotive environments. | Prefer for high-frequency digital I/O protection where sub-ns switching dominates over leakage or thermal robustness. |
Compared with BAW56VL and MMBD7000LT1G, the BAW156VL uniquely combines AEC-Q101 compliance, sub-picoamp leakage, and 0.8 µs trr - making it the only choice for automotive analog signal paths demanding simultaneous precision, speed, and qualification.

FAQ
Is the BAW156VL pin-compatible with the BAW56 series?
Yes - both share identical SOT23 pinning: Pin 1 = K1, Pin 2 = K2, Pin 3 = CA. However, BAW156VL exhibits significantly lower leakage (3 pA vs. 5 nA) and faster trr (0.8 µs vs. 4 µs), so direct substitution requires verification of system-level leakage tolerance and switching speed margins.
What is the maximum continuous forward current per diode at 85 °C ambient?
Per Figure 1 in the datasheet, the maximum permissible continuous forward current is 160 mA for single-diode operation and 140 mA for dual-diode operation at Tamb = 85 °C on standard FR4 PCB - derived from thermal resistance (Rth(j-a) = 500 K/W) and Ptot = 250 mW limit.
Does the BAW156VL support wave soldering?
Yes - Nexperia provides a dedicated wave soldering footprint (Figure 9) with 1.4 mm pad width, 2.2 mm length, and 4.5 mm transport direction spacing. Peak temperature must not exceed 260 °C for ≤10 s, and preheat ramp rate should be ≤3 °C/s to avoid delamination.
How does the common-anode configuration affect PCB layout for differential signal protection?
The CA pin allows symmetrical placement of K1 and K2 relative to differential traces (e.g., CANH/CANL), enabling matched-length clamping paths with identical parasitic inductance. This preserves common-mode rejection ratio (CMRR) and avoids skew-induced jitter in high-speed differential receivers.
