Product details
Overview
BAW101E6433HTMA1 from Infineon Technologies is a silicon switching diode in SOT143 package, configured as two parallel diodes for high-voltage medium-speed switching. It features 300 V reverse voltage rating, 250 mA continuous forward current, 1.3 V max forward voltage at 100 mA, 6 pF diode capacitance at 0 V, and 1 µs typical reverse recovery time - used in automotive ignition coil drivers and flyback snubber circuits.
For engineers reviewing the BAW101E6433HTMA1 datasheet, BAW101E6433HTMA1 pinout, BAW101E6433HTMA1 application, or BAW101E6433HTMA1 equivalent, key selection criteria include its AEC-Q101 qualification, parallel dual-diode configuration, 300 V VR rating, 1 µs trr performance, and thermal resistance ≤330 K/W junction-to-soldering-point.
Technical Context
This device integrates two electrically insulated silicon PN junctions in a single SOT143 package, enabling independent high-voltage switching paths with shared thermal path. Its parallel configuration supports redundancy or current sharing in automotive inductive load switching, while maintaining isolation between anode-cathode pairs.
The diode is optimized for medium-speed switching (trr ≤ 1 µs) under repetitive 300 V reverse bias and 250 mA DC forward conduction, with thermal design constrained by RthJS ≤ 330 K/W and maximum junction temperature of 150 °C - critical for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 300 V - supports direct connection to 24 V automotive systems with ≥10× safety margin against transients up to ISO 7637-2 Pulse 5a. |
| Forward Current (IF) | 250 mA continuous - sufficient for driving small-signal relay coils or gate resistors in IGBT/MOSFET snubbers. |
| Reverse Recovery Time (trr) | 1 µs typical - enables operation up to ~300 kHz switching in flyback auxiliary windings without excessive switching loss. |
| Diode Capacitance (CT) | 6 pF at 0 V - low enough to minimize capacitive coupling noise in high-dV/dt ignition driver feedback paths. |
| Junction Temperature (Tj) | 150 °C max - allows operation in engine compartment ambient up to 125 °C with appropriate PCB copper area. |
| Thermal Resistance (RthJS) | ≤330 K/W - defines minimum required solder pad area and via count for thermal relief when mounted on 2-layer FR-4. |
Pinout & Package
SOT143 package: 4-pin surface-mount plastic case with gull-wing leads, 1.3 mm body width, 2.9 mm length, 1.15 mm height, and standardized 0.95 mm pitch. Pin 1 marked by notch or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Primary high-side switching node; connects to inductive load return path in ignition coil driver stage. |
| Pin 2 | Cathode of Diode 1 | Common cathode node shared with Pin 4; routed to ground or low-side switch source in snubber topology. |
| Pin 3 | Anode of Diode 2 | Redundant or secondary switching path; used for dual-coil drivers or fault-isolated backup channel. |
| Pin 4 | Cathode of Diode 2 | Electrically isolated cathode terminal - enables independent clamping of two separate inductive loads. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain applications including engine control modules and transmission solenoid drivers. |
| Parallel dual-diode structure | Enables current sharing or functional redundancy without external wiring - reduces board space vs. discrete dual-Diodes. |
| RoHS-compliant Pb-free package | Meets EU Directive 2011/65/EU and automotive ELV requirements; compatible with lead-free reflow profiles (peak 260 °C). |
| Low reverse leakage | ≤0.15 µA at 250 V and 150 °C - ensures stable clamping voltage over full automotive temperature range. |
Applications
| Automotive Ignition Coil Driver | Flyback Converter Snubber |
|---|---|
Use Scenario: Clamping voltage spikes during primary coil de-energization in gasoline engine distributorless ignition systems. IC Role / Device Role / Timing Role: High-voltage freewheeling diode absorbing inductive kickback energy into capacitor-resistor network. Use Value: Prevents MOSFET drain overvoltage beyond 300 V rating while maintaining <1 µs turn-off timing alignment with spark event. | Use Scenario: Suppressing voltage overshoot across transformer primary winding in offline AC-DC flyback converters. IC Role / Device Role / Timing Role: Fast-recovery clamp diode in RCD snubber circuit limiting peak voltage to safe margin below MOSFET breakdown. Use Value: 6 pF capacitance minimizes parasitic resonance with snubber resistor, preserving 300 kHz switching stability. |
| Engine Control Unit (ECU) Solenoid Interface | Dual-Channel Inductive Load Protection |
Use Scenario: Driving fuel injector or variable valve timing solenoids requiring fast turn-off and EMI suppression. IC Role / Device Role / Timing Role: Reverse-biased protection diode across solenoid coil terminals to limit back-EMF during PWM deactivation. Use Value: 250 mA IF rating matches typical solenoid hold current; 150 °C Tj supports under-hood mounting near intake manifold. | Use Scenario: Isolating two independent inductive loads (e.g., turbocharger wastegate + EGR valve) sharing common ground plane. IC Role / Device Role / Timing Role: Dual-anode, common-cathode configuration providing independent clamping paths with no cross-talk. Use Value: Electrically insulated junctions prevent fault propagation between channels - critical for ASIL-B system partitioning. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV21W,115 (Nexperia) | Single diode, 250 V VR, 250 mA IF, 50 ns trr - faster but lower voltage rating. | Limited to 24 V systems with smaller transients; not AEC-Q101 qualified. | Select when speed > voltage margin is prioritized and automotive qualification is not required. |
| STTH1R06 (STMicroelectronics) | Single diode, 600 V VR, 1 A IF, 75 ns trr - higher voltage/current but larger SOD-123 package. | Requires more PCB area; lacks dual-diode integration for compact dual-load designs. | Select when 600 V transient immunity is mandatory and board space permits larger footprint. |
Compared with BAV21W and STTH1R06, BAW101E6433HTMA1 uniquely delivers AEC-Q101 compliance, dual-diode integration in SOT143, and balanced 300 V/1 µs performance - making it optimal for space-constrained automotive inductive load interfaces where channel isolation and qualification are mandatory.

FAQ
Is BAW101E6433HTMA1 pin-compatible with standard SOT143 diodes like BAV99?
No. While both use SOT143 packaging, BAW101E6433HTMA1 has a unique parallel dual-diode configuration (Anode1–Cathode1 and Anode2–Cathode2), whereas BAV99 is a dual-series diode. Pin mapping differs: BAW101 pins 1/2 and 3/4 are independent anode/cathode pairs, not series-connected.
What is the maximum allowable PCB temperature rise for reliable operation at 250 mA?
At 250 mA forward current and 1.3 V VF, power dissipation is ~325 mW. With RthJS ≤ 330 K/W and max Tj = 150 °C, the solder point temperature must stay ≤ 116 °C - requiring ≥ 40 mm² of 2-oz copper pour with 4 thermal vias under the package to limit ΔT to ≤34 K.
Does the "parallel" configuration mean the diodes share the same cathode internally?
No. The datasheet specifies "parallel" refers to electrical connection topology in application circuits - the device contains two physically and electrically isolated diodes in one package. Pins 2 and 4 are separate cathodes, enabling independent routing and true channel isolation.
Can BAW101E6433HTMA1 replace BAW101S in existing designs?
Yes, with verification. Both share identical electrical specs and SOT143 package, but BAW101E6433HTMA1 uses Pb-free terminations and updated traceability coding (E6433HTMA1). Thermal and switching behavior are identical; reflow profile must be adjusted for lead-free solder compatibility.
