Product details
Overview
BAS70E6433HTMA1 from Infineon Technologies is a silicon Schottky diode in SOD323 package, configured as a single discrete device with 70 V reverse voltage rating, 70 mA forward current, and 300 mV forward voltage at 1 mA. It serves as a high-speed switching diode for voltage clamping and signal mixing in compact consumer and industrial electronics.
For engineers reviewing the BAS70E6433HTMA1 datasheet, BAS70E6433HTMA1 pinout, BAS70E6433HTMA1 application, or BAS70E6433HTMA1 equivalent, key selection criteria include low forward voltage for power-sensitive detection circuits, sub-2 pF capacitance at 0 V for RF signal integrity, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve fast switching (100 ps reverse recovery time) and minimal conduction loss. Its 1.5 pF typical junction capacitance at 0 V and 1 MHz supports high-frequency signal routing without significant phase distortion.
The device operates across –55 °C to +125 °C and maintains stable VF matching (≤20 mV spread in dual configurations) - critical for precision detector and clamp circuits where thermal drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping of transient spikes up to automotive load-dump levels |
| Forward Current (IF) | 70 mA - sufficient for low-power logic-level signal steering and sensing |
| Forward Voltage (VF) | 300 mV @ 1 mA - enables ultra-low-loss detection in battery-powered sensor nodes |
| Junction Capacitance (CT) | 1.5 pF @ 0 V, 1 MHz - preserves bandwidth in RF mixer and antenna switch applications |
| Reverse Recovery Time (τrr) | 100 ps - ensures clean edge transitions in >100 MHz digital signal routing |
| Thermal Resistance (RthJS) | 310 K/W - defines maximum steady-state power dissipation under PCB-constrained thermal conditions |
| Operating Temperature | –55 °C to +125 °C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
Package: SOD323 - surface-mount plastic case, 1.7 mm × 1.25 mm footprint, 0.95 mm height, suitable for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Automotive Signal Clamping | RF Signal Mixing |
|---|---|
Use Scenario: Protecting CAN transceiver inputs from ESD and load-dump transients in body control modules. IC Role / Device Role: Fast-acting voltage clamp placed between signal line and ground rail. Use Value: 70 V VR rating absorbs ISO 7637-2 Pulse 5a surges; 100 ps τrr prevents latch-up during fast-edge interference. | Use Scenario: Frequency conversion stage in 2.4 GHz ISM-band receiver front-end. IC Role / Device Role: Passive mixer diode in balanced ring configuration. Use Value: 1.5 pF CT minimizes insertion loss; low VF ensures high conversion efficiency at –10 dBm LO drive. |
| Low-Power Sensor Detection | Logic-Level Translation Clamp |
Use Scenario: Peak detection in battery-operated environmental sensor output stages. IC Role / Device Role: Signal envelope detector feeding ADC input. Use Value: 300 mV VF at 1 mA enables accurate sub-1 V signal capture without active amplification. | Use Scenario: Level-shifting I²C lines between 1.8 V microcontroller and 3.3 V peripheral. IC Role / Device Role: Bidirectional voltage limiter on SDA/SCL lines. Use Value: Low IR (≤0.1 µA) avoids pull-up current error; SOD323 size fits tight pitch layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | VF = 375 mV @ 10 mA; CT = 1.2 pF; SOT-23 package (larger footprint) | Higher IF rating (200 mA) but higher thermal resistance (400 K/W) | Prefer when higher surge current handling is required and board area permits larger package |
| NSR0230P2T5G | VF = 270 mV @ 10 mA; CT = 2.5 pF; same SOD-323 footprint | Higher leakage (1 µA @ 30 V); not AEC-Q101 qualified | Choose only for cost-sensitive non-automotive designs where lowest VF dominates over reliability |
Compared with SBAT54LT1G and NSR0230P2T5G, BAS70E6433HTMA1 uniquely balances AEC-Q101 compliance, 310 K/W thermal resistance, and 300 mV VF at 1 mA - making it optimal for space-constrained automotive and industrial signal conditioning where long-term reliability and low-voltage detection coexist.

FAQ
Is BAS70E6433HTMA1 pin-compatible with other BAS70 variants?
No - while all BAS70-series diodes share functional equivalence, BAS70E6433HTMA1 uses the SOD323 package with anode/cathode terminals in fixed orientation. Other variants like BAS70-04W (SOT-323) or BAS70-06W (SOT-343) have different pinouts and thermal footprints, requiring layout revision for substitution.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is 150 °C. Under continuous DC operation at 70 mA and ambient 25 °C, junction temperature rise is limited by RthJS (310 K/W), resulting in ~22 °C rise - well within safe margin. Derating curves in the datasheet define usable IF vs. TS limits.
Does this diode support bidirectional ESD protection?
No - BAS70E6433HTMA1 is a unidirectional Schottky diode. For bidirectional ESD protection, a dedicated TVS array (e.g., ESD5Z series) or back-to-back Schottky pair is required; this part functions only as forward-biased clamp or rectifier.
Can BAS70E6433HTMA1 replace BAT54 in existing designs?
Yes, with verification - both are SOD323 Schottky diodes, but BAS70E6433HTMA1 has lower VF (300 mV vs. 320 mV @ 1 mA) and tighter CT (1.5 pF typ. vs. 2.0 pF). Layout compatibility is identical; however, AEC-Q101 qualification adds reliability assurance not present in standard BAT54.
