Product details
Overview
BZV55C3V6 from Taiwan Semiconductor is a surface-mount Zener diode with nominal zener voltage 3.6 V, ±5% tolerance, 500 mW power dissipation, and 5 mA test current, used for low-voltage stabilization and reference in DC/DC converters and adapters.
For engineers reviewing the BZV55C3V6 datasheet, BZV55C3V6 pinout, BZV55C3V6 application, or BZV55C3V6 equivalent, key selection criteria include zener voltage accuracy (3.4–3.8 V), dynamic impedance (85 Ω at 5 mA), leakage current (≤2 µA at 1.0 V reverse), and MMELF package compatibility with J-STD-002 soldering standards.
Technical Context
The BZV55C3V6 operates as a single-die, hermetically sealed glass Zener diode optimized for stable voltage regulation under low-current conditions. It delivers precise 3.6 V reference with 5 mA test current and maintains ≤2 µA leakage at 1.0 V reverse bias.
Its thermal design supports junction temperatures from –65 °C to +175 °C, with 300 °C/W junction-to-ambient thermal resistance. The device uses a cathode-band polarity indicator and matte tin-plated leads compatible with standard reflow profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4–3.8 V (±5% tolerance at 5 mA; ensures stable reference within tight low-voltage rails) |
| Power Dissipation (PD) | 500 mW (supports continuous regulation in space-constrained SMT designs without forced cooling) |
| Zener Impedance (ZZT) | 85 Ω max at IZT = 5 mA (low dynamic impedance enables minimal output voltage variation under load transients) |
| Leakage Current (IR) | ≤2 µA at VR = 1.0 V (ensures negligible standby current in battery-sensitive circuits) |
| Junction Temperature Range | –65 °C to +175 °C (enables operation in automotive under-hood and industrial control environments) |
| Forward Voltage (VF) | 1.0 V at IF = 10 mA (defines forward conduction threshold for bidirectional protection or clamping use cases) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F (Diodes Inc.) | Same 3.6 V nominal, ±5%, but SOD-323 package (smaller footprint, higher thermal resistance) | Preferred where board area is constrained; less suitable for high ambient temperature operation due to 400 °C/W RθJA | Select when layout density outweighs thermal performance requirements |
| BZX584-C3V6 (Nexperia) | Same 3.6 V, ±5%, but SOD-523 package and 350 mW rating (lower power handling) | Suitable for ultra-low-power sensor nodes; not recommended for adapter or DC/DC feedback where >350 mW dissipation occurs | Select only for sub-100 mW reference applications with strict size limits |
Compared with MMBZ5226BS-7-F and BZX584-C3V6, the BZV55C3V6 offers superior thermal robustness (300 °C/W) and higher power margin (500 mW), making it preferred for industrial adapters and DC/DC converters operating across wide ambient ranges.

FAQ
What is the zener voltage tolerance of the BZV55C3V6?
The BZV55C3V6 has a nominal zener voltage of 3.6 V with a guaranteed tolerance of ±5%, resulting in a validated range of 3.4 V to 3.8 V when tested at 5 mA. This tolerance is specified per the manufacturer's H2301 datasheet revision and applies under standard pulse-test conditions (30 ms duration). The BZV55C3V6 maintains this specification across its qualified operating temperature range.
What package type does the BZV55C3V6 use, and is it RoHS-compliant?
The BZV55C3V6 uses the MMELF (DO-213AA) surface-mount package with matte tin-plated leads and is fully RoHS-compliant per EU Directive 2011/65/EU. Its hermetically sealed glass construction meets J-STD-002 solderability requirements, and the package outline conforms to JEDEC standards. The BZV55C3V6 is supplied on 13" tape-and-reel (10,000 units per reel).
What is the maximum power dissipation rating for the BZV55C3V6?
The BZV55C3V6 is rated for 500 mW maximum power dissipation at 25 °C ambient temperature. Its junction-to-ambient thermal resistance is 300 °C/W, meaning power derating begins above 25 °C per the published thermal curve. At 75 °C ambient, the usable power drops to approximately 330 mW. This rating applies to the BZV55C3V6 in standard MMELF mounting on FR-4 PCB with no added copper pour.
How does the leakage current of the BZV55C3V6 compare at low reverse voltages?
The BZV55C3V6 exhibits ≤2 µA leakage current at 1.0 V reverse voltage (VR), per its official electrical specifications. This low leakage ensures minimal error current in high-impedance feedback networks-critical for precision DC/DC converter references. The value is measured at 25 °C and remains stable across the full –65 °C to +175 °C junction temperature range, as confirmed in the BZV55C3V6 characterization data.
Can the BZV55C3V6 be used in place of higher-voltage BZV55C variants?
No-the BZV55C3V6 is specifically characterized and binned for 3.6 V zener voltage and cannot substitute for other variants (e.g., BZV55C5V1 or BZV55C12) without circuit redesign. Each part in the BZV55C family has unique voltage, impedance, and leakage parameters. Substituting the BZV55C3V6 for a different voltage grade would violate regulation accuracy, potentially causing system malfunction. Always verify voltage match before replacement.
