Product details
Overview
BAV99UE6359HTMA1 from Infineon Technologies is a dual-series-connected silicon switching diode in SC74 (SOT-363) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time, optimized for high-speed signal routing and ESD protection in USB data lines and I²C bus interfaces.
For engineers reviewing the BAV99UE6359HTMA1 datasheet, BAV99UE6359HTMA1 pinout, BAV99UE6359HTMA1 application, or BAV99UE6359HTMA1 equivalent, key selection criteria include its low 1.25 V forward voltage at 150 mA, 1.5 pF junction capacitance at 0 V, AEC-Q101 qualification, RoHS-compliant lead-free construction, and thermal resistance of ≤260 K/W (junction-to-soldering point).
Technical Context
This dual-diode configuration operates as a series-connected pair sharing a common cathode node, enabling bidirectional clamping and fast transient suppression in low-voltage digital signal paths. Its 4 ns trr and 1.5 pF CT support >100 MHz signal integrity in USB 2.0 and SMBus applications.
The device is thermally characterized with RthJS ≤260 K/W and maximum junction temperature of 150 °C, allowing operation up to 125 °C ambient when mounted on standard FR-4 PCBs with recommended pad layout per SC74 footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 80 V - supports rail-to-rail clamping in 3.3 V and 5 V logic systems without breakdown |
| trr (Reverse Recovery Time) | 4 ns - enables clean switching in >100 MHz digital signal paths with minimal overshoot |
| CT (Capacitance) | 1.5 pF @ 0 V - preserves signal edge rate and minimizes loading on high-speed I²C/USB lines |
| VF (Forward Voltage) | 1250 mV @ 150 mA - ensures low conduction loss in active-clamp and level-shift configurations |
| RthJS | ≤260 K/W - allows sustained 200 mA DC operation with ≤52 °C junction rise above solder point |
| Tj (Max Junction Temp) | 150 °C - meets automotive under-hood and industrial control environment requirements |
Pinout & Package
BAV99UE6359HTMA1 is housed in an SC74 (SOT-363) surface-mount package with six terminals in a 2.9 mm × 1.9 mm outline and 0.65 mm pitch. Pin 1 marking is indicated by a dot or beveled corner per JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first diode in series string; connects to signal source in clamp topology |
| 2 | Cathode of Diode 1 / Anode of Diode 2 | Shared internal node; forms midpoint of dual-diode series path for bidirectional conduction |
| 3 | Cathode of Diode 2 | Common output node tied to ground or reference rail in ESD protection circuits |
| 4 | Anode of Diode 1 | Redundant anode connection (same net as Pin 1); improves current sharing and thermal distribution |
| 5 | Cathode of Diode 1 / Anode of Diode 2 | Redundant shared node (same net as Pin 2); enhances reliability under surge conditions |
| 6 | Cathode of Diode 2 | Redundant cathode connection (same net as Pin 3); lowers effective series resistance in clamping path |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-series switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 (Nexperia) | RthJS ≤160 K/W; same SC74 package but lower thermal resistance; VF = 1200 mV @ 150 mA | Better thermal performance in high-density layouts; identical pinout and clamping function | Select when board space is constrained and junction temperature must stay below 130 °C under 200 mA DC load |
| MMBD7000LT1G (ON Semiconductor) | Single-diode SOT-23; 100 V VR, 4 ns trr, but no dual-series configuration; requires external series pairing | Lacks integrated dual-series topology; needs two devices and extra routing for equivalent function | Choose only if SC74 footprint is unavailable and discrete assembly is acceptable for cost-sensitive designs |
Compared with BAV99UE6359HTMA1, BAV99W offers superior thermal dissipation for sustained current, while MMBD7000LT1G sacrifices integration for higher reverse voltage margin but increases layout complexity and component count.

FAQ
What is the pin 1 identification method for BAV99UE6359HTMA1?
Pin 1 is identified by a beveled corner or small dot adjacent to terminal 1 on the top surface of the SC74 package, consistent with JEDEC MO-178 standard. The marking layout follows Infineon's laser-marked format with type code "A7s" and date code in YY/MM format.
Does BAV99UE6359HTMA1 support bidirectional ESD clamping?
Yes - its dual-series configuration creates a symmetric conduction path between Pins 1–2–3 and Pins 4–5–6, enabling equal clamping behavior for positive and negative transients without external biasing, verified per IEC 61000-4-2 testing.
Can BAV99UE6359HTMA1 replace BAV99S in existing designs?
Yes, with thermal verification - both share identical SC74 package and electrical specs, but BAV99UE6359HTMA1 has RthJS ≤260 K/W versus BAV99S's ≤260 K/W (same value), so no derating is needed; pinout and marking are fully compatible.
What is the maximum allowable PCB temperature at the solder joint?
The datasheet specifies TS ≤113 °C for BAV99U variants; therefore, the solder joint temperature must not exceed 113 °C during steady-state operation to maintain Ptot = 250 mW and prevent junction overheating beyond 150 °C.
