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, 410 mV max forward voltage at 1.0 mA, 100 nA max reverse leakage at 50 V, and 5.0 ns reverse recovery time. It serves as rail-to-rail data line protection and polarity guard in automotive signal conditioning circuits.
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, symmetrical terminal layout for bidirectional protection, and ultra-small SOT363 footprint for space-constrained 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 conduction up to 15 mA, and <2.0 pF junction capacitance at 0 V bias - enabling high-speed signal line clamping without loading.
The array uses PN junction guard ring construction for ESD and transient immunity, supports operation from –55 °C to +125 °C, and delivers thermal resistance of 625 °C/W (junction-to-ambient) on FR-4 board with recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 70 V - Maximum DC blocking voltage per diode; defines safe operating range for polarity protection and rail clamp circuits. |
| IF (mA) | 1.0 mA - Rated continuous forward current; sets baseline for low-power signal path protection applications. |
| VF MAX (V) | 0.41 V @ 1.0 mA - Low forward drop minimizes voltage loss in battery-sensitive or low-voltage logic interfaces. |
| IR MAX (µA) | 0.10 µA @ 25°C - Ultra-low leakage ensures minimal standby current draw in always-on automotive modules. |
| tRR (ns) | 5.0 ns - Fast recovery enables use in >100 MHz data line protection without signal distortion. |
| CT (pF) | 2.0 pF @ 0 V - Low junction capacitance preserves signal integrity on high-speed I²C, CAN, or LIN bus lines. |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic package (2.15 mm × 2.10 mm × 1.0 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 line or power rail. |
| C1 | Cathode 1 | Output/return terminal for first diode; ties to reference rail (e.g., GND or VCC). |
| A2 | Anode 2 | Input terminal for second independent Schottky diode; used for complementary or differential line protection. |
| C2 | Cathode 2 | Output/return terminal for second diode; enables dual-rail or bidirectional clamping topology. |
| A3 / C3 | Not connected (NC) | Unused terminals in BAS70DW-04Q's symmetrical dual-diode configuration; no internal connection. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 410 mV max at 1.0 mA - reduces power dissipation and voltage offset in precision sensor front-ends. |
| Fast switching speed | 5.0 ns reverse recovery - supports protection of digital signals up to 100+ MHz without timing skew. |
| PN junction guard ring | Integrated ESD/Transient suppression - meets IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) without external components. |
| AEC-Q101 qualification | Automotive-grade reliability - qualified for under-hood and infotainment systems requiring PPAP and IATF 16949 traceability. |
Applications
| Automotive Data Line Protection | Rail-to-Rail Signal Clamping |
|---|---|
Use Scenario: Protecting LIN bus transceivers against load dump and ESD events in body control modules. IC Role / Device Role / Timing Role: Dual Schottky array provides bidirectional clamping between signal line and VBAT/GND rails. Use Value: 0.41 V forward drop ensures minimal impact on LIN voltage thresholds; 100 nA leakage avoids battery drain in sleep mode. |
Use Scenario: Preventing overvoltage on ADC input pins during hot-plug events in automotive sensor hubs. IC Role / Device Role / Timing Role: Anode-to-signal / cathode-to-rail configuration limits input swing to safe levels without resistive attenuation. Use Value: 2.0 pF capacitance avoids bandwidth reduction; 5 ns tRR prevents sampling errors during fast transients. |
| Polarity Protection Circuit | Low-Power Bridge Rectifier |
Use Scenario: Reverse-battery protection for 12 V telematics power supplies in fleet management units. IC Role / Device Role / Timing Role: One diode channel placed in series with input rail to block reverse current flow. Use Value: 70 V VR rating accommodates ISO 7637-2 pulse 5a (up to 60 V); 0.41 V VF limits power loss at 100 mA. |
Use Scenario: Full-wave rectification of low-current AC signals (<1 mA) in battery-backed real-time clock circuits. IC Role / Device Role / Timing Role: Two diodes configured as half-bridge legs to convert bipolar sensor output to unidirectional DC. Use Value: Symmetrical SOT363 layout simplifies routing; 100 nA IR ensures microamp-level quiescent current retention. |
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 |
|---|---|---|---|
| SBAS70DW-04Q | Same electrical specs and SOT363 package; differs only in marking code (K74 vs K74A) and date-code traceability format. | No functional difference; identical AEC-Q101 qualification and thermal performance. | Select when sourcing from alternate Diodes wafer lots with updated traceability requirements. |
| NSR20F70NXT5G | Higher IF rating (200 mA), higher VF (0.55 V @ 10 mA), larger SOD-523 package (1.2 × 0.8 mm), non-automotive grade. | Lacks AEC-Q101 certification and guard ring; unsuitable for safety-critical automotive modules. | Consider only for cost-sensitive industrial prototypes where qualification and ESD robustness are secondary. |
Compared with SBAS70DW-04Q, this part offers identical functionality and qualification; versus NSR20F70NXT5G, it trades higher current capability for guaranteed automotive reliability, lower leakage, and tighter capacitance control in a smaller footprint.

FAQ
Is BAS70DW-04Q pin-compatible with BAS70TWQ?
Yes - both share identical SOT363 pinout and symmetrical dual-diode configuration (A1/C1 and A2/C2 active, A3/C3 NC). BAS70TWQ uses K73 marking and same electrical specs, differing only in internal layout symmetry documentation; no PCB redesign is needed for substitution.
What is the maximum operating temperature for continuous use?
The device is rated for continuous operation from –55 °C to +125 °C ambient temperature. Derating begins above 25 °C per Figure 4: power dissipation drops linearly to zero at 125 °C, with 625 °C/W thermal resistance on standard FR-4 layout.
Does BAS70DW-04Q meet IEC 61000-4-2 ESD requirements?
Yes - its integrated PN junction guard ring provides inherent ESD protection rated to IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact), verified per AEC-Q101 stress testing protocols; no external TVS diodes required for basic compliance.
Can BAS70DW-04Q be used in high-frequency RF applications?
No - while its 2.0 pF capacitance and 5 ns tRR support data rates up to ~100 MHz, it lacks specified RF parameters (e.g., S-parameters, insertion loss) and is not characterized for impedance-controlled RF matching; intended for digital/data line protection, not RF signal paths.
