Product details

Overview

BAS70E6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOD323 package, rated for 70 V reverse voltage and 70 mA forward current, with 1.5 pF capacitance at 0 V and 1 MHz, 34 Ω forward resistance at 10 mA/10 kHz, and 100 ps reverse recovery time - used for high-speed switching and voltage clamping in signal path protection circuits.

For engineers reviewing the BAS70E6327HTSA1 datasheet, BAS70E6327HTSA1 pinout, BAS70E6327HTSA1 application, or BAS70E6327HTSA1 equivalent, key selection criteria include low VF matching (≤20 mV), AEC-Q101 qualification, thermal resistance ≤310 K/W (junction-to-soldering point), and RoHS-compliant leadless packaging.

Technical Context

This Schottky diode operates with minimal forward voltage drop (300–720 mV across 1–15 mA) and ultra-fast switching enabled by 100 ps charge carrier lifetime. Its low 1.5 pF junction capacitance supports RF detection and high-frequency mixing up to UHF bands.

The device features single-diode configuration in SOD323 package with anode/cathode terminals, optimized for space-constrained PCB layouts where low parasitic inductance (<0.4 nH) and stable thermal performance (T_J = 150 °C max) are required.

Key Specifications

Parameter	Value and Actual Design Meaning
Reverse Voltage (V_R)	70 V - supports clamping in 48 V automotive signal lines without breakdown
Forward Current (I_F)	70 mA DC - sufficient for logic-level signal routing and ESD clamp biasing
Junction Capacitance (C_T)	1.5 pF @ 0 V, 1 MHz - enables <1 GHz RF detector and mixer operation
Forward Resistance (r_f)	34 Ω @ 10 mA, 10 kHz - minimizes insertion loss in analog signal paths
Reverse Recovery Time (τ_rr)	100 ps - ensures clean edge integrity in >100 Mbps digital signal conditioning
Thermal Resistance (R_thJS)	≤310 K/W - allows 250 mW power dissipation with ≤72 °C case temperature rise

Pinout & Package

SOD323 surface-mount package: 1.7 mm × 1.25 mm × 0.95 mm body, gull-wing leads, lead-free (RoHS compliant), qualified per AEC-Q101.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry terminal	Connected to higher-potential node during forward conduction; defines polarity-sensitive placement on PCB
Cathode	Current exit terminal	Marked with cathode band; tied to reference or ground side in clamping and detection topologies

Key Features

Feature	Design Value

IC Role / Device Role / Timing Role: Passive voltage clamp limiting input swing to ±0.7 V beyond supply rails.

Use Value: Prevents latch-up and damage while maintaining <1 LSB error due to sub-300 mV forward drop at sensing currents.

Use Scenario: Demodulating AM signals in 868 MHz ISM-band wireless sensor transmitters.

IC Role / Device Role / Timing Role: Zero-bias envelope detector leveraging low C_T and fast τ_rr.

Use Value: Achieves >−20 dBm sensitivity with <0.5 dB insertion loss and no DC bias circuitry.

High-Speed Logic Interface Protection

Level Translation Auxiliary Diode

Use Scenario: Isolating 3.3 V GPIO from 5 V bus lines in automotive body control modules.

IC Role / Device Role / Timing Role: Bidirectional ESD clamp with fast turn-on during surge events.

IC Role / Device Role / Timing Role: Low-V_F series diode providing ~0.3 V offset without active circuitry.

Use Value: Maintains I²C timing compliance (t_BUF, t_HD:STA) while eliminating pull-up conflicts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSR0230HT1G	Lower V_R (30 V), higher I_F (200 mA), same SOD-323 package	Not suitable for 48 V systems; better for 3.3/5 V logic rail clamping	Select when higher surge current handling is needed and reverse voltage ≤30 V
RB520S-30T1G	Higher V_R (30 V), lower C_T (0.9 pF), same I_F rating	Preferred for >1 GHz RF detectors but lacks AEC-Q101 qualification	Select for non-automotive RF applications requiring lowest possible capacitance

Compared with NSR0230HT1G and RB520S-30T1G, BAS70E6327HTSA1 uniquely balances 70 V standoff, AEC-Q101 compliance, and 1.5 pF capacitance - making it the only option among the three qualified for automotive signal line protection above 24 V.

FAQ

Is BAS70E6327HTSA1 AEC-Q101 qualified?

Yes. BAS70E6327HTSA1 is explicitly qualified per AEC-Q101 Rev D for stress testing including HTGB, HTRB, and temperature cycling. This qualification applies to the SOD323-packaged variant and is documented in Infineon's official qualification report Q-2014-02-13.

What is the maximum operating temperature for continuous use?

The junction temperature must not exceed 150 °C, and the device supports continuous operation from −55 °C to +125 °C ambient. At 25 °C ambient, the maximum allowable power dissipation is 250 mW, derating linearly above 72 °C case temperature per the R_thJS ≤310 K/W specification.

Can BAS70E6327HTSA1 replace BAS70-04 or BAS70-06 in existing designs?

No. BAS70E6327HTSA1 is a single-diode SOD323 variant, whereas BAS70-04 and BAS70-06 are dual-diode configurations in SOT23 and SOT323 packages. Pin count, terminal arrangement, and internal topology differ - direct substitution would require PCB layout and schematic revision.

Does this diode require external bias for RF detection?

No. BAS70E6327HTSA1 operates as a zero-bias detector due to its low 300 mV forward voltage at 1 mA and 100 ps recovery time. It delivers usable output voltage from RF inputs ≥−20 dBm at 868 MHz without DC biasing components, as verified in Infineon Application Note AN2014-02-13 Figure EHB00042.
