Product details
Overview
BZB84-C3V6,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 3.6 V nominal Zener voltage (±5 % tolerance), 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves as a precision voltage reference and overvoltage clamp in low-power analog and automotive signal conditioning circuits.
For engineers reviewing the BZB84-C3V6,215 datasheet, BZB84-C3V6,215 pinout, BZB84-C3V6,215 application, or BZB84-C3V6,215 equivalent, this device is selected for dual-rail clamping, ESD-protected I/O buffering, and AEC-Q101-compliant voltage regulation where space-constrained SMT layout and thermal stability at 150 °C junction temperature are critical.
Technical Context
This dual-Zener diode integrates two independent 3.6 V Zener elements sharing a common anode (Pin 3), enabling bidirectional voltage clamping across differential or complementary signal paths. Its ±5 % tolerance (C-grade) and −3.5 to 0 mV/K temperature coefficient ensure stable regulation under ambient shifts from −55 °C to +150 °C.
Designed for surface-mount reliability, it delivers 90 Ω typical differential resistance at IZ = 5 mA and supports surge handling up to 6.0 A peak reverse current (100 µs square wave, Tj = 25 °C), with thermal resistance of 100 K/W from junction to solder point on FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4 V to 3.8 V at IZ = 5 mA - defines clamping threshold for bidirectional protection |
| Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets continuous DC bias limit for thermal design |
| Differential Resistance (rdif) | 600 Ω max at IZ = 5 mA - determines regulation stiffness under load variation |
| Reverse Current (IR) | 5 µA max at VR = 1 V - ensures low leakage in standby signal paths |
| Non-repetitive Peak Power (PZSM) | 40 W for tp ≤ 100 µs - enables transient surge suppression without failure |
| Junction Temperature (Tj) | 150 °C maximum - supports operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress test qualification |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | Single Zener, 3.3 V, SOT23, ±5 %, 225 mW Ptot | Unidirectional only; requires two devices for bidirectional clamping | Choose when board area allows discrete placement and cost sensitivity outweighs layout efficiency |
| BZX84-C3V6,215 | Single Zener, 3.6 V, SOT23, ±5 %, 300 mW Ptot, no common-anode pairing | Lacks integrated dual-clamp topology; needs external anode tie | Select if existing design uses single-diode footprints and thermal margin permits separate mounting |

FAQ
What is the maximum continuous reverse current the BZB84-C3V6,215 can sustain?
The device supports up to 200 mA forward current (IF), but its Zener operation is specified at test currents of 1 mA or 5 mA. At IZ = 5 mA, it maintains 3.4–3.8 V regulation; sustained reverse current beyond 50 mA risks exceeding 300 mW Ptot unless derated per ambient temperature curves in the datasheet.
How does the common-anode configuration affect PCB layout versus discrete Zeners?
The shared anode (Pin 3) eliminates need for external copper tie between two anodes, reducing parasitic inductance and layout complexity. This configuration enables tighter spacing between cathodes (Pins 1 and 2), improving symmetry in differential clamping and minimizing skew in high-speed signal paths.
Is the 450 pF diode capacitance measured at DC or AC conditions?
Capacitance is specified at f = 1 MHz and VR = 0 V, per Table 8 footnote [1]. This AC measurement reflects dynamic junction capacitance during signal coupling, not static DC blocking behavior-critical for evaluating high-frequency noise filtering and USB signal integrity impact.
Can BZB84-C3V6,215 replace BZB84-B3V6 in an existing design?
Yes, but with ±5 % tolerance instead of ±2 %. The B-grade offers tighter regulation (3.53–3.67 V vs. C-grade's 3.4–3.8 V), so substitution may increase output voltage variation in precision references. Verify system-level margin for worst-case clamping thresholds before redesign.
