Product details

Overview

BA89502VH6327XTSA1 from Infineon Technologies is a general-purpose silicon switching diode in SC-79 (SOD-523) package, rated for 100 V repetitive peak reverse voltage (V_RWM), 200 mA average forward current (I_F(AV)), and 4 ns reverse recovery time (t_rr). It serves as a high-speed clamping or signal routing diode in DC-DC converter feedback paths and USB port protection circuits.

For engineers reviewing the BA89502VH6327XTSA1 datasheet, BA89502VH6327XTSA1 pinout, BA89502VH6327XTSA1 application, or BA89502VH6327XTSA1 equivalent, key selection criteria include its low leakage (I_R = 100 nA @ V_R = 100 V), fast t_rr, compact SOD-523 footprint, and guaranteed surge current rating (I_FSM = 1.5 A).

Technical Context

This diode employs a planar epitaxial silicon structure optimized for fast recovery and low forward voltage drop. Its junction capacitance is specified at 2.5 pF @ V_R = 0 V, supporting high-frequency signal integrity in ESD-coupled data lines.

The device operates across –55 °C to +150 °C junction temperature range and meets AEC-Q101 stress test requirements for automotive-grade reliability, with defined thermal resistance (R_thJL = 350 K/W) enabling accurate power dissipation modeling in space-constrained PCB layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RWM	100 V - Maximum continuous reverse voltage before breakdown; sets safe operating margin in 48 V automotive supply rail clamping
I_F(AV)	200 mA - Average forward current handling; supports sustained operation in low-power logic-level signal steering
t_rr	4 ns - Reverse recovery time; enables use in >10 MHz switching applications without tail current losses
I_R @ V_R = 100 V	100 nA - Reverse leakage current; ensures minimal standby power loss in always-on sensor interface circuits
C_j @ V_R = 0 V	2.5 pF - Junction capacitance; maintains signal rise/fall times < 1 ns in high-speed digital line protection
I_FSM	1.5 A - Non-repetitive peak forward surge current; withstands IEC 61000-4-5 Level 3 transient events

Pinout & Package

Package: SC-79 (SOD-523), 2-terminal surface-mount plastic package with cathode band marking; dimensions 1.2 × 0.8 × 0.6 mm (L × W × H), compatible with standard 0402 reflow profiles.

Pin/Terminal	Circuit Role	Design Meaning

FAQ

Is BA89502VH6327XTSA1 suitable for 5 V logic-level clamping?

Yes. With V_RWM = 100 V and I_R = 100 nA at 100 V, it provides ample margin and negligible leakage when used to clamp 5 V signals to GND or 5 V rails. Its 4 ns t_rr ensures no timing skew in 5 V CMOS or TTL interfaces up to 50 MHz.

What is the maximum PCB temperature rise during continuous 200 mA operation?

At 200 mA DC forward current and ambient 25 °C, junction temperature rise is approximately 35 °C using standard 1 oz copper with 10 mm² thermal pad, based on R_thJL = 350 K/W and V_F ≈ 1.05 V. Derating to 150 mA is recommended above 85 °C ambient.

Does BA89502VH6327XTSA1 have a built-in ESD protection structure?

No. BA89502VH6327XTSA1 is a passive silicon diode without integrated ESD structures. It functions as an external clamping element-typically paired with TVS diodes or RC filters-to divert ESD energy away from sensitive ICs per IEC 61000-4-2 Level 4.

Can this diode replace BAS16 in existing designs?

Yes, with design verification. BA89502VH6327XTSA1 matches BAS16's V_RWM (100 V), I_F(AV) (200 mA), and SOD-523 package, but offers faster t_rr (4 ns vs. 4–6 ns) and lower C_j (2.5 pF vs. 4 pF), improving high-frequency performance in new layouts.
