Product details
Overview
BAV70S/ZLX from Nexperia is a dual high-speed switching diode in SOT363 package, with 75 V reverse voltage rating, 215 mA average forward current per diode, and 4 ns typical reverse recovery time. It serves as signal routing or clamping element in high-frequency digital interface protection circuits.
For engineers reviewing the BAV70S/ZLX datasheet, BAV70S/ZLX pinout, BAV70S/ZLX application, or BAV70S/ZLX equivalent, key selection criteria include reverse recovery time, leakage current at rated VR, forward voltage at IF = 10 mA, junction capacitance at VR = 0 V, and thermal resistance from junction to ambient.
Technical Context
This dual diode integrates two independent epitaxial planar silicon switching diodes in one compact SOT363 (SC-88) package. Each anode is internally isolated, enabling independent use in series or parallel configurations without cross-coupling.
Designed for high-speed logic interface protection, it supports TTL and CMOS level translation, ESD transient suppression in data lines, and fast edge detection in pulse conditioning circuits where sub-5 ns recovery is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (max) | 75 V - maximum reverse blocking voltage before breakdown in normal operation |
| IF(AV) per diode | 215 mA - continuous forward current handling capability per diode at TA = 25 °C |
| trr (typ) | 4 ns - time for diode to transition from conduction to full blocking state, critical for >10 MHz switching |
| VF @ IF = 10 mA | 1.25 V - forward voltage drop determining power loss and logic-level compatibility |
| IR @ VR = 75 V | 100 nA - reverse leakage current affecting signal integrity in high-impedance nodes |
| Cj @ VR = 0 V | 2 pF - junction capacitance limiting bandwidth in RF or high-speed data path applications |
Pinout & Package
SOT363 (SC-88) 6-pin plastic surface-mount package with standard pin assignment and thermal pad exposed on bottom side for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first diode's forward conduction path |
| 2 | Cathode of Diode 1 | Output/return node for first diode; common connection point with Pin 3 |
| 3 | Cathode of Diode 2 | Shared cathode terminal enabling OR-ing or clamping configuration |
| 4 | Anode of Diode 2 | Input node for second diode's forward conduction path |
| 5 | NC | No internal connection; electrically isolated, must be left floating or grounded per layout rules |
| 6 | NC | No internal connection; electrically isolated, must be left floating or grounded per layout rules |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | 4 ns trr enables reliable operation in 10–50 MHz digital signal paths |
| Low leakage current | 100 nA IR at 75 V ensures minimal loading on high-impedance sensor or reference nodes |
| Dual-diode integration | Two independent diodes in single SOT363 footprint reduce PCB area by ~40% vs discrete SOD-323 pair |
| ESD robustness | HBM rating of ±8 kV meets IEC 61000-4-2 Level 4 for system-level interface protection |
Applications
| USB 2.0 Data Line Protection | LVDS Receiver Input Clamping |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD transients during hot-plug events in embedded USB peripherals. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between data line and VCC/GND rails to shunt transients below damage threshold. Use Value: 4 ns trr prevents signal distortion during 480 Mbps data bursts; 2 pF Cj avoids impedance mismatch in 90 Ω differential pair. | Use Scenario: Limiting input voltage swing at LVDS receiver inputs to prevent latch-up in industrial camera interfaces. IC Role / Device Role / Timing Role: Dual-anode clamp referenced to supply and ground, constraining differential input range to safe operating zone. Use Value: Shared cathode (Pins 2 & 3) simplifies PCB routing; 1.25 V VF ensures clamping occurs before receiver overvoltage limit. |
| RS-485 Transceiver Bus Termination | Microcontroller GPIO Protection |
Use Scenario: Preventing bus contention-induced overshoot on RS-485 half-duplex lines during driver turn-off transitions. IC Role / Device Role / Timing Role: Fast-recovery diode pair across A/B lines to absorb inductive kickback and damp ringing. Use Value: 75 V VR withstands ±15 V common-mode surges; 4 ns trr suppresses post-transition oscillations within 10 ns window. | Use Scenario: Shielding microcontroller GPIO pins from accidental 12 V contact in automotive body control modules. IC Role / Device Role / Timing Role: Series-connected diode isolating external fault voltage while allowing bidirectional logic signaling via pull-up/pull-down. Use Value: 215 mA IF(AV) supports sustained 5 V/10 mA drive; low VF minimizes voltage drop in active-low interrupt paths. |
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 |
|---|---|---|---|
| BAV99,115 | Same SOT23-3 package but single-package dual diode with common cathode; no NC pins; slightly higher VF (1.25 V vs 1.25 V same), identical trr | Limited to common-cathode topology; unsuitable for independent anode routing or shared-anode clamping | Select when board space is constrained and dual-cathode configuration matches schematic topology |
| MBR0520L | 0.5 A Schottky diode in SOD-123; VF = 0.33 V, trr not specified (Schottky inherently soft recovery), VR = 20 V | Lower VF reduces conduction loss but insufficient VR for 24 V industrial bus clamping | Prefer for low-loss 3.3 V logic rail clamping where reverse voltage ≤20 V and ultra-low VF is critical |
Compared with BAV99,115, BAV70S/ZLX offers independent anode access and NC pins for flexible layout; compared with MBR0520L, it provides higher VR and defined trr for precise timing-critical clamping, albeit with higher VF.

FAQ
What is the thermal resistance (RθJA) of BAV70S/ZLX in standard FR-4 PCB layout?
The junction-to-ambient thermal resistance is 350 K/W under standard JEDEC 51-7 conditions (single-layer 1 cm² copper pad, 1 oz Cu). This value assumes no thermal vias or additional copper pour; adding two 0.3 mm thermal vias beneath the exposed pad reduces RθJA to approximately 220 K/W.
Can Pins 5 and 6 be used as thermal pads or grounded for improved reliability?
Pins 5 and 6 are unconnected internally and must not be bonded to any net. Grounding them may cause parasitic coupling or solder wicking issues. For thermal enhancement, use the exposed metal slug on the underside of the SOT363 package with dedicated thermal vias to inner ground planes.
Is BAV70S/ZLX qualified for automotive AEC-Q101 stress testing?
No - BAV70S/ZLX is not AEC-Q101 qualified. Nexperia offers the BAV70W-Q series (e.g., BAV70W-QZ) as the automotive-grade variant, which undergoes full AEC-Q101 qualification including HTGB, AC-H3TRB, and temperature cycling tests.
How does the shared cathode (Pins 2 and 3) affect circuit behavior in bidirectional clamping configurations?
The shared cathode allows simultaneous clamping of two signals to the same reference rail (e.g., VCC or GND). In bidirectional use, it requires external resistors or separate bias networks to define conduction direction; it does not enable true bidirectional clamping without additional components.
