Product details
Overview
BAV70W/ZLF from Nexperia is a high-speed switching double diode in SOT323 (SC-70) package, featuring common-cathode dual configuration, 100 V reverse voltage rating, ≤4 ns reverse recovery time, and ≤1.5 pF junction capacitance - deployed in EMI-filtered signal routing and high-frequency clamp circuits in telecom line interface modules.
For engineers reviewing the BAV70W/ZLF datasheet, BAV70W/ZLF pinout, BAV70W/ZLF application, or BAV70W/ZLF equivalent, this page delivers verified electrical parameters, validated SC-70 terminal mapping, real-world switching use cases, thermal resistance data (625 K/W), and direct alternatives with documented differences in leakage and recovery behavior.
Technical Context
The BAV70W/ZLF integrates two independent silicon switching diodes sharing a common cathode terminal, enabling compact dual-path clamping or steering without inter-device mismatch. Its low trr (≤4 ns) and low Cd (≤1.5 pF) are achieved via optimized epitaxial doping and shallow junction design, supporting operation up to 100 MHz in RF detector and sample-and-hold front ends.
Rated for 100 V repetitive peak reverse voltage and 175 mA DC forward current per diode, it operates across −65 °C to +150 °C ambient, with thermal resistance Rth(j-a) = 625 K/W on standard FR4 PCB - confirming suitability for space-constrained industrial control I/O protection where self-heating must remain below 35 K at 100 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports clamping of transient surges up to IEC 61000-4-5 Level 3 (1 kV) in protected analog inputs. |
| Reverse Recovery Time (trr) | ≤4 ns - enables clean switching in 50–100 MHz clock distribution networks without pulse distortion. |
| Junction Capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal loading in RF bias tee and antenna switch control paths. |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in active biasing circuits with <100 mW dissipation budget. |
| Reverse Leakage (IR) | 0.5 µA at 80 V, 25 °C - maintains high-impedance state integrity in precision voltage reference dividers. |
| Thermal Resistance (Rth(j-a)) | 625 K/W - defines maximum steady-state power (200 mW) before junction exceeds 150 °C on standard FR4 layout. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-terminal, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body, designed for reflow soldering with defined footprint per Figure 8 (sot323_fr).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode path; used for signal steering or polarity-sensitive clamping. |
| 2 | Anode (Diode 2) | Independent input node for second diode; enables dual-rail protection or differential signal conditioning. |
| 3 | Common Cathode | Shared output/return node - simplifies PCB routing in dual-anode configurations and reduces net count by one. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns ensures minimal timing skew in dual-path logic-level translators operating at >25 MHz. |
| Low junction capacitance | Cd ≤ 1.5 pF preserves signal integrity in 50 Ω RF paths up to 1 GHz when used as DC blocking element. |
| Common-cathode dual configuration | Reduces board area by 30% vs. discrete diode pair; eliminates cathode trace mismatch in matched-path designs. |
| Low leakage at high temperature | IR ≤ 100 µA at 80 V, 150 °C - sustains accuracy in automotive under-hood sensor signal conditioning. |
Applications
| Telecom Line Interface Protection | USB 2.0 ESD Clamp Circuit |
|---|---|
|
Use Scenario: Protecting RS-485 transceiver inputs against fast transients (IEC 61000-4-4) while preserving signal edge fidelity. IC Role / Device Role / Timing Role: Dual-anode clamping diode array referenced to common cathode tied to TVS rail. Use Value: 4 ns trr prevents pulse rounding on 10 Mbps differential signals; 1.5 pF Cd avoids 3 dB roll-off above 200 MHz. |
Use Scenario: Bidirectional ESD protection on D+ and D− lines of USB 2.0 host ports. IC Role / Device Role / Timing Role: Common-cathode dual diode providing low-capacitance path to VBUS and GND rails. Use Value: 0.5 µA IR at 25 °C maintains bus idle voltage stability; SOT323 footprint fits tight 0.5 mm trace spacing. |
| RF Detector Bias Network | Industrial PLC Analog Input Guarding |
|
Use Scenario: Providing temperature-stable DC bias to Schottky RF detector diodes in 900 MHz ISM band receivers. IC Role / Device Role / Timing Role: Low-leakage forward-biased path stabilizing detector operating point across −40 °C to +85 °C. Use Value: IR ≤ 30 nA at 25 V, 25 °C ensures <0.1% gain drift; VF matching between diodes minimizes offset error. |
Use Scenario: Overvoltage clamping on 4–20 mA current loop inputs exposed to field wiring faults. IC Role / Device Role / Timing Role: Dual-path crowbar device limiting input voltage to ±15 V during 30 V surge events. Use Value: 100 V VR rating withstands 2× supply rail overvoltage; 200 mW Ptot allows sustained 100 mA fault current handling. |
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 |
|---|---|---|---|
| BAV99W | Higher trr (≤6 ns), higher Cd (≤2 pF), same VR (100 V), identical SOT323 package | Marginally lower bandwidth in RF detector use; acceptable for <50 MHz switching | Select when cost sensitivity outweighs sub-ns timing requirements and layout allows +0.5 pF loading. |
| MMBD7000 | Lower VR (70 V), same trr (≤4 ns), same Cd (≤1.5 pF), same SOT23 package (not pin-compatible) | Not suitable for 80–100 V transient suppression; requires PCB redesign due to different pinout | Choose only if system max reverse stress is ≤70 V and SOT23 footprint is already standardized. |
Compared with BAV99W and MMBD7000, the BAV70W/ZLF uniquely balances 100 V capability, 4 ns speed, and 1.5 pF capacitance in SOT323 - making it optimal for space-limited, high-voltage, high-frequency clamping where both voltage margin and edge fidelity are critical.

FAQ
What is the maximum continuous forward current per diode in the BAV70W/ZLF?
The BAV70W/ZLF supports 175 mA DC forward current per diode at Tamb ≤ 25 °C, derating linearly to zero at 150 °C junction temperature. This rating assumes mounting on FR4 PCB with single-sided copper and standard SOT323 footprint per Figure 8 - exceeding this current without thermal mitigation risks permanent junction damage.
Is the BAV70W/ZLF suitable for automotive applications?
No - the BAV70W/ZLF is explicitly marked as non-automotive qualified in its revision history (Table 8). It lacks AEC-Q101 qualification, automotive-grade screening, and guaranteed operation across the full −40 °C to +125 °C extended temperature range required for automotive ECUs. Use BAV70W-Q variants for automotive deployment.
How does the common-cathode configuration affect PCB layout compared to discrete diodes?
The common-cathode structure reduces net count by one and eliminates cathode trace length mismatch between diodes - critical for balanced clamping in differential signaling. Layout requires only three pads (vs. six for discrete diodes), with shared cathode pad acting as central return node, simplifying ground plane routing and reducing parasitic inductance in high-dI/dt paths.
What is the thermal resistance from junction to ambient under standard conditions?
Rth(j-a) is 625 K/W when mounted on an FR4 PCB with single-sided copper, tin-plated finish, and standard SOT323 footprint (per Table 6). This value assumes free-air convection and no additional copper pour; adding 25 mm² thermal pad beneath the package reduces Rth(j-a) to ~200 K/W, enabling higher sustained power dissipation.
