Product details
Overview
BAS70-02W E6327 from Infineon is a silicon Schottky diode in SOD323 package configured as a single discrete device, rated for 70 V reverse voltage, 70 mA forward current, and 250 mW total power dissipation at TS ≤ 107 °C, used for high-speed switching and voltage clamping in signal path protection circuits.
For engineers reviewing the BAS70-02W E6327 datasheet, BAS70-02W E6327 pinout, BAS70-02W E6327 application, or BAS70-02W E6327 equivalent, key selection criteria include low forward voltage (VF = 375–705 mV at IF = 10 mA), ultrafast recovery time (τrr ≤ 100 ps), low junction capacitance (CT = 1.5–2 pF at VR = 0 V), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve fast switching with minimal stored charge, enabling operation in RF detector, high-frequency clamp, and level-shifting applications up to ~1 GHz. Its 1.5–2 pF capacitance at zero bias and sub-100 ps reverse recovery support signal integrity in 50 Ω systems.
The device operates across –55 °C to +125 °C ambient, with thermal resistance RthJS ≤ 130 K/W (junction-to-soldering point), allowing stable performance under pulsed loads where duty cycle D = 0 and pulse width tp ≥ 10 µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - Supports clamping and protection in 48 V automotive and 24 V industrial supply rails. |
| Forward Current (IF) | 70 mA DC - Suitable for low-power signal routing, not power conversion or load switching. |
| Forward Voltage (VF) | 375–705 mV @ 10 mA - Enables low-loss signal detection and minimizes voltage drop in bias networks. |
| Reverse Recovery Time (τrr) | ≤100 ps - Permits use in >1 GHz RF mixing and high-speed logic interface clamping. |
| Junction Capacitance (CT) | 1.5–2 pF @ VR = 0 V, f = 1 MHz - Matches impedance in 50 Ω RF paths without significant loading. |
| Thermal Resistance (RthJS) | ≤130 K/W - Allows sustained operation at TS ≤ 107 °C on standard FR4 PCB with minimal copper area. |
| Reverse Leakage (IR) | ≤0.1 µA @ VR = 50 V - Ensures negligible standby current in battery-backed sensing nodes. |
Pinout & Package
SOD323 surface-mount package: 2-terminal, single-diode configuration with cathode marked by band; footprint compatible with JEDEC MO-203AA standard; body dimensions 1.7 × 1.25 × 0.95 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry node under forward bias | Connected to higher-potential signal or supply side in clamping/detection paths. |
| Cathode (K) | Current exit node under forward bias; marked by band | Connected to reference (e.g., ground or bias rail) to enable conduction during overvoltage or positive peaks. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
| RoHS-compliant, Pb-free | Meets EU Directive 2011/65/EU; no lead in solderable terminations or die attach. |
| Low VF matching (ΔVF ≤ 20 mV) | Ensures consistent turn-on behavior in dual-diode arrays or parallel configurations. |
| Ultra-low CT and τrr | Enables integration into 50 Ω RF front-ends without external tuning or compensation. |
Applications
| RF Signal Detection | Automotive CAN Bus Protection |
|---|---|
Use Scenario: Demodulating AM/FM envelope signals in low-power receiver front-ends. IC Role / Device Role / Timing Role: Schottky detector diode converting RF carrier amplitude to baseband DC voltage. Use Value: 375 mV VF at 10 mA enables detection sensitivity down to –20 dBm with <1 dB insertion loss. | Use Scenario: Clamping transients on CAN_H/CAN_L lines in 12 V vehicle networks. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor protecting PHY IC inputs. Use Value: 70 V VR and ≤100 ps τrr limit clamping response time to <1 ns, preventing bus lockup during ESD events. |
| High-Speed Logic Level Shifting | Low-Power Sensor Biasing |
Use Scenario: Interfacing 3.3 V microcontroller GPIO to 5 V peripheral I/O with voltage translation. IC Role / Device Role / Timing Role: Passive clamp diode establishing safe logic-high threshold between domains. Use Value: 2 pF CT avoids signal edge degradation on 10–50 MHz digital lines; 70 mA IF supports multi-load fanout. | Use Scenario: Providing precision bias current to photodiode or thermistor in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Low-leakage forward-biased current source with stable VF vs. temperature. Use Value: ≤0.1 µA IR at 50 V ensures <1 nA error current in 1 µA bias networks, preserving ADC accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | VF = 450 mV typ. @ 10 mA; CT = 2.5 pF; SOD-123 package (larger footprint) | Higher capacitance limits use above 500 MHz; less suitable for RF detection | Preferred where board space allows larger package and RF bandwidth < 300 MHz |
| RB520S-30T1G | VF = 370 mV typ. @ 10 mA; VR = 30 V; same SOD-323 footprint | Lower VR restricts use to ≤24 V systems; unsuitable for 48 V automotive clamping | Select only for cost-sensitive 3.3/5 V logic interfaces with no high-voltage transients |
Compared with NSR0230HT1G and RB520S-30T1G, BAS70-02W E6327 uniquely balances 70 V VR, sub-100 ps τrr, and SOD323 size-making it the only option qualified for AEC-Q101 automotive signal clamping above 30 V while maintaining RF usability.

FAQ
Is BAS70-02W E6327 suitable for bidirectional ESD protection?
No. BAS70-02W E6327 is a unidirectional Schottky diode with anode and cathode terminals. For bidirectional ESD protection, a dedicated TVS diode such as ESD5Z5.0T1G or a dual-common-cathode Schottky array like BAS70-04W is required. This part functions only in forward conduction or reverse blocking-not symmetrical clamping.
What is the maximum allowable soldering temperature for BAS70-02W E6327?
The SOD323 package supports standard reflow profiles per IPC/JEDEC J-STD-020. Peak temperature must not exceed 260 °C for ≤10 seconds. Hand soldering requires iron tip temperature ≤300 °C with contact time <3 seconds per terminal to avoid die metallization damage or bond wire lift.
Does BAS70-02W E6327 have a specified junction-to-case thermal resistance?
No-only junction-to-soldering-point thermal resistance (RthJS ≤ 130 K/W) is specified. Junction-to-case (RthJC) is not published because the SOD323 package lacks a defined thermal pad or case surface; thermal performance depends entirely on PCB copper area and via design beneath the terminals.
Can BAS70-02W E6327 replace BAT54S in a common-cathode dual-diode application?
No. BAS70-02W E6327 is a single-diode SOD323 device, whereas BAT54S is a dual-diode common-cathode SOT-23 package. They differ in pin count, configuration, and footprint. A direct replacement would require either two BAS70-02W units or a functionally matched dual-diode part like BAS70-04W.
