FAQ

What is the maximum reverse current before breakdown for BZX84-C10/DG/B4VL?

The device exhibits less than 100 nA reverse leakage at 7.6 V, and begins measurable Zener conduction above 9.5 V. Breakdown is defined at 5 mA test current, where voltage stabilizes at 10 V ±5%. No guaranteed minimum breakdown current is specified - operation below 1 mA yields progressively higher dynamic impedance.

Can BZX84-C10/DG/B4VL be used in parallel for higher power handling?

No - Zener diodes exhibit manufacturing spread in voltage and tempco, causing current imbalance and thermal runaway when paralleled. For higher power, select a single higher-rated device like MMBZ5240B or use active regulation instead.

Is the SOT-23 package lead-free and RoHS compliant?

Yes - BZX84-C10/DG/B4VL is manufactured with lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH SVHC regulations, as confirmed in Nexperia's official compliance documentation.

What is the typical junction-to-ambient thermal resistance (R_θJA) for this device?

The typical R_θJA is 500 K/W under standard JEDEC PCB mounting conditions (single-layer 1 cm² copper pad). Actual value depends on PCB layout; adding thermal vias or larger copper areas can reduce it to ~250 K/W in optimized designs.
