Product details
Overview
BZB84-C2V7,215 from Nexperia is a dual common-anode Zener diode in SOT23 (TO-236AB) package, rated for 2.7 V nominal Zener voltage (±5 % tolerance), 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves voltage regulation and overvoltage protection in compact automotive and industrial power rails.
For engineers reviewing the BZB84-C2V7,215 datasheet, BZB84-C2V7,215 pinout, BZB84-C2V7,215 application, or BZB84-C2V7,215 equivalent, this part supports dual-channel clamping in space-constrained designs requiring AEC-Q101 qualified discrete protection with tight voltage tolerance and low thermal resistance.
Technical Context
This dual-Zener device integrates two independent Zener diodes sharing a common anode (Pin 3), enabling bidirectional voltage clamping or complementary reference generation. Its ±5 % VZ tolerance (2.5 V to 2.9 V at IZ = 5 mA) and low differential resistance (≤600 Ω) ensure stable regulation under varying load conditions.
Designed for surface-mount reliability, it features AEC-Q101 qualification, 150 °C maximum junction temperature, and thermal resistance of 100 K/W from junction to solder point-critical for sustained operation in automotive ambient environments up to +125 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Single Zener, 2.7 V, ±5 %, SOT23 - no dual configuration | Requires two devices for dual-rail clamping; increases board area and BOM count | Select when only unidirectional clamping is needed and space permits discrete placement |
| BZX84-C2V7,215 | Single Zener, same VZ/tolerance/package - lacks second cathode | Cannot implement common-anode bidirectional protection; unsuitable for differential clamping | Choose only for simple shunt regulation where dual functionality is unnecessary |
Compared with MMBZ5221BS-7-F and BZX84-C2V7,215, the BZB84-C2V7,215 uniquely delivers dual-channel clamping in one footprint-reducing PCB real estate by 35 % and eliminating inter-device timing skew in fast transient suppression.

FAQ
What is the maximum continuous reverse current the BZB84-C2V7,215 can sustain?
The device has no specified continuous reverse current rating; its steady-state operation is governed by total power dissipation (300 mW max at Tamb ≤ 25 °C). At 2.7 V, this corresponds to ~111 mA average Zener current before thermal derating applies. Operation above this requires ambient temperature reduction per the Rth(j-a) = 417 K/W curve.
Can BZB84-C2V7,215 be used for bidirectional ESD protection on a single signal line?
No-it is not designed for bidirectional clamping on one net. Its dual cathodes share a common anode, so it functions as two anode-referenced Zeners. For true bidirectional protection (e.g., I/O pins), a dedicated TVS like PESD5V0S1BA is required; this part serves best in dual-rail or split-supply configurations.
How does the ±5 % tolerance affect precision in voltage reference applications?
At 2.7 V nominal, ±5 % yields a 2.5–2.9 V window-sufficient for reset thresholding or coarse regulation but not for sub-1 % analog references. For higher precision, pair with an op-amp buffer or select a bandgap-based reference; this Zener excels in cost-sensitive, moderate-accuracy roles where AEC-Q101 and dual topology add value.
Is the SOT23 package lead-free and RoHS compliant?
Yes-Nexperia confirms the BZB84-C2V7,215 is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH SVHC regulations. The device marking "UA*" (per Table 4) indicates RoHS-compliant packaging, with "*" denoting manufacturing location (Hong Kong).
