Product details
Overview
BAS28E6359HTMA1 from Infineon Technologies is a silicon switching diode in SOT143 package, configured as a parallel pair for high-speed switching applications. It features 80 V reverse voltage rating, 4.5 A non-repetitive surge forward current, 4 ns reverse recovery time, and is qualified to AEC-Q101 for automotive use in signal routing and clamping circuits.
For engineers reviewing the BAS28E6359HTMA1 datasheet, BAS28E6359HTMA1 pinout, BAS28E6359HTMA1 application, or BAS28E6359HTMA1 equivalent, key selection criteria include reverse recovery speed, thermal resistance (≤360 K/W), junction temperature limit (150 °C), and RoHS-compliant Pb-free packaging for automotive-grade reliability.
Technical Context
The BAS28E6359HTMA1 integrates two identical silicon switching diodes in a single SOT143 package with shared cathode configuration (parallel pair). Its 4 ns trr and low 2 pF capacitance at 0 V support >100 MHz signal switching in digital logic interfaces and ESD-protected I/O stages.
Thermal design relies on junction-to-soldering-point resistance ≤360 K/W, enabling operation up to 150 °C junction temperature. The device meets AEC-Q101 stress test requirements for automotive under-hood and infotainment subsystems where fast transient response and thermal robustness are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail clamping with 3.3× safety margin |
| Reverse Recovery Time (trr) | 4 ns - enables clean edge transitions in 100+ MHz clock distribution and data lines |
| Diode Capacitance (CT) | 2 pF @ 0 V, 1 MHz - minimizes signal loading in high-speed GPIO and USB 2.0 stubs |
| Surge Forward Current (IFS) | 4.5 A @ 1 µs - handles ESD-induced transients per IEC 61000-4-2 Level 4 (8 kV contact) |
| Junction Temperature (Tj) | 150 °C - allows placement near power ICs in engine control units without derating |
| Thermal Resistance (RthJS) | ≤360 K/W - defines minimum PCB copper area required for thermal relief at 200 mA DC load |
Pinout & Package
SOT143 package: 4-pin plastic surface-mount package with gull-wing leads, 1.3 mm × 1.7 mm footprint, 0.95 mm height, and pin 1 marked by chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first switching path; routed to signal source in clamp or steering configuration |
| Pin 2 | Cathode (common) | Shared cathode connection - tied to reference rail (e.g., VCC or GND) for dual-diode operation |
| Pin 3 | Anode of Diode 2 | Independent input node for second switching path; enables dual-channel protection or signal routing |
| Pin 4 | Not connected | No internal connection - electrically isolated; must be left floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including powertrain sensors and body control modules |
| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU without exemption; suitable for lead-free reflow assembly |
| Parallel-pair configuration | Reduces board space vs. discrete dual-diode solutions while maintaining independent anode control |
| Low leakage at high temperature | IR ≤ 50 µA @ 75 V, 150 °C - ensures stable bias in under-hood ambient conditions |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS216,115 | Same SOT143 package, but single-diode configuration; trr = 4 ns, VR = 100 V | Lacks parallel-pair functionality; requires two devices for dual-path designs | Select when only one switching path is needed and higher VR margin is prioritized |
| BAT54C,215 | SOT323 package; dual common-cathode; trr = 5 ns; CT = 10 pF @ 0 V | Higher capacitance limits use above 20 MHz; smaller footprint but lower power dissipation (200 mW) | Prefer for space-constrained consumer electronics where speed <50 MHz suffices |
Compared with BAS216,115 and BAT54C,215, the BAS28E6359HTMA1 uniquely delivers dual-anode, single-cathode switching in SOT143 with optimized 4 ns trr and 2 pF CT-making it the only choice for compact, high-frequency automotive signal routing requiring paired paths and AEC-Q101 validation.

FAQ
What is the maximum continuous forward current for BAS28E6359HTMA1?
The maximum continuous forward current is 200 mA at TA = 25 °C with TS ≤ 31 °C. Derating applies above 31 °C ambient; full 200 mA is sustainable only with adequate PCB copper thermal relief per the datasheet's IF vs. TS curve.
Is BAS28E6359HTMA1 suitable for bidirectional ESD protection?
No - it is a unidirectional switching diode with anode-cathode polarity. For bidirectional ESD protection, a dedicated TVS array like ESD204 or PESD5V0S1BA must be used; BAS28E6359HTMA1 functions only in forward conduction or reverse blocking mode.
Does the SOT143 package support automated optical inspection (AOI)?
Yes - the SOT143 package has clearly defined pin 1 marking (chamfered corner), consistent lead geometry, and sufficient contrast for standard AOI systems. Its 0.65 mm pitch and gull-wing leads are compatible with IPC-A-610 Class 2 and Class 3 solder joint inspection criteria.
How does BAS28E6359HTMA1 differ from BAS28W?
BAS28E6359HTMA1 uses the SOT143 package with RthJS ≤ 360 K/W and TS ≤ 31 °C limit, while BAS28W uses SOT343 with RthJS ≤ 190 K/W and TS ≤ 103 °C. The 'W' variant supports higher ambient temperatures but has different pinout and thermal profile.
