Product details
Overview
BAS70-04TE6327 from Infineon Technologies is a silicon Schottky diode in SOT323 package configured as a common-cathode dual diode, rated for 70 V reverse voltage, 70 mA forward current, and 250 mW total power dissipation at ≤48 °C case temperature. It delivers low forward voltage (720 mV at 15 mA), 2 pF capacitance at 0 V, and 100 ps reverse recovery time for high-speed switching in signal routing and clamping circuits.
For engineers reviewing the BAS70-04TE6327 datasheet, BAS70-04TE6327 pinout, BAS70-04TE6327 application, or BAS70-04TE6327 equivalent, key selection criteria include dual common-cathode topology, thermal derating limits (TS ≤ 48 °C), VF matching (≤20 mV spread), and AEC-Q101 qualification for automotive signal conditioning.
Technical Context
This dual Schottky diode integrates two independent anodes sharing one cathode terminal, enabling bidirectional clamping or dual-path signal steering without cross-conduction. Its low 1.4 nH series inductance and 34 Ω forward resistance at 10 kHz support RF detector and mixer applications up to UHF frequencies.
The device operates across –55 °C to +125 °C ambient, with junction temperature limited to 150 °C and thermal resistance from junction to soldering point ≤410 K/W - critical for PCB layout in space-constrained automotive control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping of transient spikes in 24 V automotive supply rails |
| Forward Current (IF) | 70 mA continuous - sufficient for logic-level signal detection and low-power analog switching |
| Forward Voltage (VF) | 720 mV at 15 mA - enables low-loss signal rectification in battery-powered sensor interfaces |
| Diode Capacitance (CT) | 2 pF at 0 V, 1 MHz - minimizes loading on high-frequency clock or RF signal paths |
| Reverse Recovery Time (τrr) | 100 ps - ensures clean edge fidelity in >100 MHz digital signal routing and sampling circuits |
| Thermal Resistance (RthJS) | ≤410 K/W - requires careful copper pour design on PCB to maintain TS ≤ 48 °C under full load |
| Operating Temperature | –55 °C to +125 °C - qualified for engine bay and transmission control unit environments |
Pinout & Package
Package: SOT323 - surface-mount plastic package with gull-wing leads, 1.3 mm × 1.7 mm footprint, 0.95 mm height, suitable for reflow assembly and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input/Anode path 1 | Accepts positive signal or voltage for clamping or detection; electrically isolated from Anode 2 |
| Cathode (Pin 2) | Common return node | Shared cathode connection for both diodes; must be routed to lowest-impedance ground or reference rail |
| Anode 2 (Pin 3) | Input/Anode path 2 | Independent second input path; enables dual-signal handling without inter-channel coupling |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual configuration | Reduces component count in dual-rail protection or differential signal conditioning circuits |
| AEC-Q101 qualification | Validated for automotive electronics including body control modules and infotainment I/O protection |
| Low VF matching (≤20 mV) | Ensures balanced conduction between channels in precision analog front-ends |
| Pb-free (RoHS compliant) | Meets EU Directive 2011/65/EU and supports lead-free reflow profiles (JEDEC J-STD-020) |
| 100 ps reverse recovery | Enables use in 100+ MHz RF detector stages without waveform distortion or timing jitter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR20F70NXT5G | Higher IF rating (200 mA), higher VF (790 mV @ 15 mA), SOD-523 package (smaller, 1.0 × 0.6 mm) | Preferred for space-constrained portable devices; less suitable where thermal derating to 48 °C is required | Select when board area is critical and peak current exceeds 70 mA |
| RB521S-40T1G | Lower VR (40 V), tighter VF matching (±5 mV), same SOT-323 package, no AEC-Q101 qualification | Suitable for consumer-grade 3.3 V/5 V logic protection but not automotive under-hood use | Select for cost-sensitive industrial controls where AEC-Q101 is not mandated |
Compared with NSR20F70NXT5G and RB521S-40T1G, BAS70-04TE6327 uniquely balances AEC-Q101 compliance, 70 V standoff, and SOT323 manufacturability - making it optimal for automotive signal conditioning where reliability, voltage margin, and assembly yield are jointly prioritized.

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies TS ≤ 48 °C for BAS70-04 variants under full 70 mA forward current. Exceeding this temperature requires derating per the IF vs. TS curve in Figure 6, with zero current permitted above 150 °C junction temperature. Thermal design must ensure solder-point temperature remains within limit using ≥100 mm² 1-oz copper pad.
Is BAS70-04TE6327 pin-compatible with BAS70-04W or BAS70-04S?
No - although all share SOT323 packaging, BAS70-04TE6327 uses standard gull-wing leads, while BAS70-04W has wettable flank leads and BAS70-04S features side-wettable flanks for automated optical inspection. Pin numbering and mechanical footprint differ slightly, requiring separate land patterns.
Does the 20 mV VF matching spec apply across temperature or only at 25 °C?
The ≤20 mV ∆VF specification applies only at TA = 25 °C and IF = 10 mA, as stated in the Electrical Characteristics table. Over temperature, VF drift is typical ±2 mV/°C per diode, so matching degrades - design margins should assume up to 50 mV spread across –40 °C to +125 °C operating range.
Can BAS70-04TE6327 be used in place of a single-diode BAS70 in existing designs?
Only if the circuit explicitly uses only one anode and ties the other anode to a fixed potential or leaves it open. The common-cathode structure means both anodes share the same cathode node - substituting into a single-diode layout risks unintended conduction paths or altered clamping thresholds unless the unused anode is properly terminated.
