Product details
Overview
BAS70DW-04Q from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, rated for 70 V reverse voltage, 1.0 mA forward current, 0.41 V max forward voltage at +25°C, 0.10 µA max reverse leakage at +25°C, and 5.0 ns reverse recovery time. It serves as polarity protection and rail-to-rail data line protection in automotive infotainment and body control modules.
For engineers reviewing the BAS70DW-04Q datasheet, BAS70DW-04Q pinout, BAS70DW-04Q application, or BAS70DW-04Q equivalent, key selection criteria include low-leakage dual-diode configuration, AEC-Q101 qualification, ultra-small SOT363 footprint, symmetrical terminal arrangement, and suitability for high-speed signal clamping in space-constrained automotive PCBs.
Technical Context
This device integrates two independent Schottky diodes in a single symmetrical SOT363 package with no orientation indicator. Each diode exhibits 70 V peak repetitive reverse voltage, sub-1 V forward voltage up to 15 mA, and <100 nA reverse current at 50 V, enabling low-loss signal routing and fast transient suppression.
The array uses PN junction guard ring technology for ESD and transient robustness, supports operation from –55°C to +125°C, and achieves 2.0 pF total capacitance at 0 V bias-critical for preserving signal integrity on high-speed data lines such as CAN FD or LIN bus interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 70 V - Maximum DC blocking voltage per diode; defines safe operating range in battery-supplied automotive circuits. |
| IF (mA) | 1.0 mA - Rated continuous forward current; suitable for low-power signal conditioning and biasing applications. |
| VF MAX (V) @ +25°C | 0.41 V - Low forward drop at 1.0 mA ensures minimal voltage loss in polarity protection paths. |
| IR MAX (µA) @ +25°C | 0.10 µA - Ultra-low leakage enables reliable rail-to-rail clamping without loading sensitive analog inputs. |
| tRR (ns) | 5.0 ns - Fast recovery supports high-frequency switching in multiplexing and re-circulating diode applications. |
| CT (pF) | 2.0 pF - Low junction capacitance preserves bandwidth on data lines up to ~100 MHz. |
| TJ Range (°C) | –55 to +125 - Full automotive temperature range compliance for under-hood and cabin-mounted ECUs. |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic package (2.15 mm × 2.10 mm × 0.95 mm), moisture sensitivity level 1, lead-free matte tin plating, weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky diode; connects to protected signal or power rail. |
| A2 | Anode 2 | Input terminal for second Schottky diode; enables dual independent protection paths. |
| A3 | Anode 3 | Not applicable - BAS70DW-04Q is dual-diode (A1/C1 & A2/C2); A3/C3 pins are unused in this variant. |
| C1 | Cathode 1 | Output/return path for first diode; typically tied to common reference or ground. |
| C2 | Cathode 2 | Output/return path for second diode; allows independent cathode routing for differential protection. |
| C3 | Cathode 3 | Not applicable - only two diodes implemented; C3 is unconnected in this configuration. |
Key Features
| Feature | Design Value |

Applications
| Automotive Polarity Protection | Rail-to-Rail Data Line Clamp |
|---|---|
Use Scenario: Reverse-battery protection on 12 V supply inputs of telematics control units and ADAS camera modules. IC Role / Device Role / Timing Role: Dual-anode Schottky array provides independent forward conduction paths while blocking reverse current during miswiring events. Use Value: Prevents system damage without adding series resistance or voltage drop beyond 0.41 V at 1 mA, preserving low-voltage margin. | Use Scenario: Bidirectional clamping of LIN bus or SENT sensor signals against ESD transients. IC Role / Device Role / Timing Role: Each diode conducts when its anode exceeds cathode by >0.41 V, shunting overvoltage to VCC or GND rails. Use Value: 2.0 pF capacitance and 5 ns recovery avoid signal distortion on 20 kbps–200 kbps serial buses. |
| Multiplexed Signal Routing | Low-Current Bridge Rectifier |
Use Scenario: Signal selection in analog multiplexer front-ends for multi-sensor vehicle stability systems. IC Role / Device Role / Timing Role: Diodes steer input signals based on bias state, leveraging low VF to minimize channel offset error. Use Value: Sub-1 mV offset drift over temperature ensures <0.1% gain error in precision sensor signal chains. | Use Scenario: AC-to-DC conversion for low-power wake-up circuitry in smart door handles and seat occupancy sensors. IC Role / Device Role / Timing Role: Two diodes form half of a full-wave bridge; remaining two paths implemented externally or via other devices. Use Value: 70 mA peak forward current rating supports microamp-level standby loads with <0.5 V total drop across both conducting diodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Single-channel, higher IF (100 mA), larger SOD-323 package, no AEC-Q101 certification. | Not suitable for dual-path protection; requires two devices and more board area. | Select only for non-automotive, cost-sensitive consumer designs where dual integration is unnecessary. |
| BAS70-04W-7-F | Same die, identical electrical specs, but in SOT323 (3-pin, single-diode per package); no symmetrical dual configuration. | Requires two placements and routing for dual protection; lacks integrated pinout symmetry. | Choose only if legacy SOT323 footprint compatibility is mandatory and board space is not constrained. |
Compared with RB050M-30TR and BAS70-04W-7-F, BAS70DW-04Q uniquely delivers AEC-Q101-qualified dual-diode functionality in a symmetrical, orientation-free SOT363 package-reducing component count, placement complexity, and PCB real estate by 50% in automotive signal protection designs.

FAQ
Is BAS70DW-04Q pin-compatible with BAS70TWQ?
Yes-both share identical SOT363 pinout and symmetrical dual-diode configuration. BAS70DW-04Q uses K74 marking and is functionally identical to BAS70TWQ (K73 marking), differing only in date-code labeling and internal lot traceability for automotive PPAP compliance.
What is the maximum reverse voltage that can be applied continuously?
The maximum continuous DC blocking voltage is 70 V per diode, verified per JEDEC JESD22-A114 test conditions. Derating is not required up to +125°C ambient, as thermal resistance (RθJA = 625°C/W) and power dissipation limits maintain junction temperature within specification.
Does BAS70DW-04Q support bidirectional ESD protection?
No-it provides unidirectional clamping: each diode conducts only when its anode is ~0.41 V above its cathode. For true bidirectional protection, external pull-up/pull-down resistors or complementary diode pairs must be added to the signal path.
Can BAS70DW-04Q replace BAT54S in existing designs?
Yes, with verification: both are dual Schottky arrays in SOT363, but BAS70DW-04Q offers lower IR (0.10 µA vs. 2.0 µA typical for BAT54S) and tighter VF distribution. Layout compatibility is confirmed, though thermal performance differs due to distinct junction-to-ambient resistance values.
