Product details
Overview
BAV70UE6359HTMA1 from Infineon Technologies is a silicon double diode in common-cathode configuration, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time. It is AEC-Q101 qualified for automotive use and housed in an SC74 (SOT-363) package with Pb-free RoHS compliance.
For engineers reviewing the BAV70UE6359HTMA1 datasheet, BAV70UE6359HTMA1 pinout, BAV70UE6359HTMA1 application, or BAV70UE6359HTMA1 equivalent, key selection criteria include fast switching performance, thermal resistance of ≤260 K/W (junction-to-soldering point), low leakage (<0.15 µA at 70 V), and suitability for space-constrained dual-diode routing in signal clamping and polarity protection circuits.
Technical Context
This dual diode operates with two anodes sharing one cathode, enabling independent but thermally coupled switching paths. Its 4 ns trr and 1.5 pF capacitance at 0 V support high-frequency signal routing up to ~100 MHz in interface protection and logic-level translation.
The SC74 package provides six terminals with defined pin 1 marking, supporting automated placement and reflow. Thermal resistance RthJS ≤ 260 K/W ensures stable operation under pulsed loads up to 1 A for 1 µs, as validated by Infineon's permissible pulse load curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports rail-to-rail clamping in 24 V automotive systems without breakdown |
| Forward Current (IF) | 200 mA DC - sufficient for LED biasing, logic input protection, and low-power signal routing |
| Reverse Recovery Time (trr) | 4 ns - enables clean edge transitions in 10–50 MHz digital signal lines and ESD transient suppression |
| Diode Capacitance (CT) | 1.5 pF @ 0 V, 1 MHz - minimizes signal distortion in high-speed data lines (e.g., USB 2.0, I²C) |
| Reverse Leakage (IR) | 0.15 µA @ 70 V, 25°C - ensures low standby power loss in always-on sensor interfaces |
| Junction Temp (Tj) | 150°C - allows operation in under-hood automotive environments with minimal derating |
| RthJS | ≤260 K/W - enables sustained 150 mA operation at TS ≤ 85°C in compact PCB layouts |
Pinout & Package
BAV70UE6359HTMA1 is packaged in SC74 (SOT-363), a 6-pin surface-mount package with symmetric pin 1 marking and 0.65 mm pitch. The device uses a common-cathode dual-diode layout with pins assigned as Anode 1, Cathode, Anode 2, and three unused or internally tied terminals per standard SC74 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input path for first diode; connects to signal source requiring clamping or steering |
| 2 | Cathode | Shared cathode node; ties both diodes to reference (e.g., VCC or GND for clamp direction) |
| 3 | Anode 2 | Input path for second diode; enables dual-path protection or polarity selection |
| 4 | No Connect | Internally unconnected; must be left floating or grounded per layout best practice |
| 5 | No Connect | Internally unconnected; no electrical function; avoid routing traces to this pad |
| 6 | No Connect | Internally unconnected; serves mechanical anchoring only; not for thermal conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| Common-cathode dual configuration | Reduces component count vs. discrete diodes in bidirectional signal clamping (e.g., RS-485 bus) |
| 4 ns reverse recovery | Minimizes switching loss and ringing in >10 MHz clock or data line protection |
| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260°C) |
| Low IR at elevated temperature | 30 µA @ 25 V, 150°C - maintains signal integrity in hot under-dash environments |
Applications
| Automotive CAN Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Bidirectional transient suppression on CAN_H/CAN_L lines in body control modules. IC Role / Device Role / Timing Role: Dual common-cathode diode providing symmetrical TVS-like clamping to ±18 V while preserving signal rise/fall times. Use Value: 4 ns trr prevents data corruption during 1 Mbps CAN signaling; 80 V VR withstands load dump transients. | Use Scenario: ESD and overvoltage protection on D+ and D− lines of embedded USB peripherals. IC Role / Device Role / Timing Role: Low-capacitance dual diode routing both data lines to VBUS or GND for ±8 kV contact ESD immunity. Use Value: 1.5 pF CT avoids signal integrity degradation; 0.15 µA IR prevents pull-up current leakage. |
| Industrial Sensor Signal Conditioning | Logic-Level Translation Interface |
Use Scenario: Input protection for analog front-end ADCs receiving 0–5 V signals from remote sensors. IC Role / Device Role / Timing Role: Dual clamping diode limiting input to supply rails, preventing latch-up in precision op-amps. Use Value: Matched VF across both diodes ensures balanced clamping thresholds; 150°C Tj rating supports operation near motor drives. | Use Scenario: Level-shifting between 3.3 V microcontroller GPIO and 5 V peripheral logic inputs. IC Role / Device Role / Timing Role: Anode-to-anode connection enabling bidirectional voltage translation via forward conduction. Use Value: 855 mV VF @ 10 mA ensures minimal voltage drop; common cathode simplifies PCB routing vs. discrete pairs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99,115 (Nexperia) | Same SC74 package, 100 V VR, 4 ns trr, but VF = 1.25 V @ 150 mA (vs. 1.25 V @ 150 mA for BAV70U) | Higher VR margin suits 48 V industrial buses; slightly higher VF increases power loss in battery-powered designs | Select when 100 V standoff is required and thermal headroom permits higher VF |
| MMBD7000LT1G (ON Semiconductor) | SOT-23-3 package, single dual-diode, 70 V VR, 4 ns trr, VF = 1.25 V @ 100 mA | Limited to single-channel dual-diode use; lacks second independent anode for true dual-path routing | Choose only if board space is constrained and dual-anode independence is not required |
Compared with BAV99,115 and MMBD7000LT1G, BAV70UE6359HTMA1 offers optimal balance of 80 V VR, 4 ns trr, and SC74 dual-anode flexibility for automotive and industrial dual-line protection-without sacrificing thermal performance or RoHS compliance.

FAQ
Is BAV70UE6359HTMA1 pin-compatible with BAV70S or BAV70W?
No. BAV70UE6359HTMA1 uses the SC74 (SOT-363) package with six terminals, while BAV70S is in SOT-363 but marked as "A4s" with identical pinout, and BAV70W is in SOT-323 (three-terminal). Pin mapping differs across packages; direct substitution requires PCB redesign.
What is the maximum continuous forward current at 105°C ambient?
At TA = 105°C, the derated forward current is approximately 120 mA, based on Infineon's IF vs. TS curve for BAV70U. This assumes proper PCB copper area for heat dissipation and junction temperature maintained below 150°C.
Does BAV70UE6359HTMA1 support bidirectional ESD protection?
Yes - configured with anodes tied to protected lines and cathode to VCC or GND, it provides bidirectional clamping. However, it does not meet IEC 61000-4-2 Level 4 alone; external series impedance is required for full compliance.
Can this diode replace a BAT54S in a common-cathode application?
Only with verification. BAT54S has lower VF (~320 mV @ 10 mA) but slower trr (~5 ns) and lower VR (30 V). BAV70UE6359HTMA1 offers higher VR and faster switching but higher VF - suitable where voltage margin and speed outweigh forward loss.
