Product details
Overview
BZT52C6V2-G from Taiwan Semiconductor is a 6.2 V ±5% tolerance surface-mount Zener diode in SOD-123 package, rated for 350 mW power dissipation and 150 °C maximum junction temperature, with 10 Ω typical dynamic impedance at 5 mA test current and 4.0 mV/°C temperature coefficient - used for precision voltage regulation and reference in low-power analog circuits.
For engineers reviewing the BZT52C6V2-G datasheet, BZT52C6V2-G pinout, BZT52C6V2-G application, or BZT52C6V2-G equivalent, key selection considerations include its 5.8–6.6 V zener voltage range, 10 Ω zener impedance at IZT = 5 mA, 3.7 V reverse leakage threshold, cathode-band polarity marking, and SOD-123 footprint compatibility with automated assembly.
Technical Context
The BZT52C6V2-G operates as a single-die, silicon planar Zener diode optimized for stable voltage clamping and reference generation in DC bias networks. Its 10 Ω dynamic impedance (ZZT) at 5 mA and 150 °C thermal limit support reliable operation in ambient temperatures up to +125 °C with derated power.
It features a nominal 6.2 V breakdown voltage with ±5% tolerance, 0.4 mV/°C temperature coefficient at 5 mA, and 3.7 V reverse leakage threshold (IR ≤ 3 µA at VR = 3.7 V), enabling predictable regulation across industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8–6.6 V (±5% tolerance at IZT = 5 mA; enables precise 6.2 V reference with tight production spread) |
| Power Dissipation (PD) | 350 mW (max continuous power at TA = 25 °C; requires thermal derating above 25 °C per 357 °C/W RθJA) |
| Zener Impedance (ZZT) | 10 Ω (typical at IZT = 5 mA; ensures low AC impedance for stable regulation under small-signal load variation) |
| Reverse Leakage (IR) | ≤3 µA at VR = 3.7 V (low standby current in high-impedance bias networks) |
| Temperature Coefficient | +0.4 mV/°C (at IZTC = 5 mA; positive TC supports compensation in multi-diode references) |
| Junction Temperature | −55 to +150 °C (supports operation in extended industrial environments without thermal shutdown) |
Pinout & Package
Package: SOD-123 - surface-mount plastic case with matte tin-plated leads, J-STD-002 solderable, UL 94V-0 rated molding compound, cathode indicated by band, weight ≈10.55 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to lower-potential node in shunt regulation; forms reference return path for bias current |
| Cathode | Zener breakdown terminal / voltage clamp input | Connected to regulated node; absorbs excess current when input exceeds 6.2 V, maintaining stable output |
Key Features
| Feature | Design Value |
|---|---|
| 5% Zener voltage tolerance | Ensures consistent 6.2 V regulation across production lots without post-assembly trimming |
| SOD-123 surface-mount package | Enables high-density PCB layout and compatibility with standard 0.95 mm pitch reflow profiles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Zener voltage 6.0–6.4 V (±3%), 200 mW PD, SOT-23 package | Lower power rating and smaller footprint; higher thermal resistance limits sustained current handling | Select when board space is constrained and peak power < 200 mW; verify thermal margin in sealed enclosures |
| 1N4735A | 6.2 V ±5%, 1 W PD, DO-41 through-hole package | Higher power capability but incompatible with SMT assembly; larger thermal mass delays response to transients | Select for prototyping or high-reliability through-hole designs where manual rework is acceptable and >350 mW clamping is required |
Compared with MMBZ5234BS-7-F and 1N4735A, the BZT52C6V2-G delivers optimal balance of SMT compatibility, 350 mW power handling, and tight 6.2 V regulation - making it preferred for volume-manufactured industrial control boards requiring automated assembly and thermal robustness.

FAQ
What is the exact zener voltage range specified for BZT52C6V2-G?
The BZT52C6V2-G has a guaranteed zener voltage range of 5.8 V to 6.6 V at test current IZT = 5 mA, reflecting its ±5% tolerance around the nominal 6.2 V rating. This range is verified per Taiwan Semiconductor's C2007 specification sheet and applies across the full operating temperature range of −55 to +150 °C.
Does BZT52C6V2-G support reflow soldering without moisture preconditioning?
Yes, the BZT52C6V2-G is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30 °C/60% RH and placed directly into reflow without baking. This eliminates moisture-related popcorning risk and simplifies SMT line integration for high-volume production.
What is the maximum reverse leakage current for BZT52C6V2-G and at what voltage is it measured?
The BZT52C6V2-G exhibits ≤3 µA reverse leakage current at VR = 3.7 V, as specified in the electrical characteristics table. This low leakage ensures minimal current draw in high-impedance bias networks and prevents unintended activation in standby-mode circuits.
Can BZT52C6V2-G be used as a substitute for BZT52C6V8-G in a 6.8 V reference design?
No - the BZT52C6V2-G is not a functional substitute for BZT52C6V8-G, as its zener voltage range (5.8–6.6 V) does not overlap with the BZT52C6V8-G's range (6.4–7.2 V). Using BZT52C6V2-G in a 6.8 V design would result in under-regulation and potential circuit malfunction.
Is the SOD-123 package of BZT52C6V2-G compatible with IPC-7351B standard land patterns?
Yes, the SOD-123 package of BZT52C6V2-G aligns with IPC-7351B generic land pattern for DO-213AA (SOD-123), with recommended pad dimensions of 1.2 × 0.8 mm and 0.95 mm center-to-center spacing. Taiwan Semiconductor's package outline drawing confirms compliance with this standard for reliable solder joint formation.
