Product details
Overview
BZG03C11TR3 from Vishay Semiconductors is a glass-passivated surface-mount Zener diode rated for 11 V nominal zener voltage (10.4–11.6 V), 3 W steady-state power dissipation at 100 °C ambient, and 600 W non-repetitive surge capability. It stabilizes reference voltages in power supply regulation, overvoltage protection, and precision biasing circuits using DO-214AC (SMA) package.
For engineers reviewing the BZG03C11TR3 datasheet, BZG03C11TR3 pinout, BZG03C11TR3 application, or BZG03C11TR3 equivalent, key selection criteria include zener voltage tolerance (±5.5%), dynamic resistance (4–7 Ω), temperature coefficient (±0.1 %/K), and thermal resistance to ambient (100–150 K/W depending on PCB layout).
Technical Context
The BZG03C11TR3 operates as a voltage-reference device via reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable long-term performance and high reliability under thermal cycling and humidity stress. The DO-214AC package supports wave and reflow soldering with Pb-free compliance per RoHS 2002/95/EC.
It delivers 11 V regulation at 50 mA test current with 4–7 Ω dynamic impedance and ±0.1 %/K temperature coefficient-critical for low-drift analog references. Junction temperature is limited to 150 °C, and storage range extends from –65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V nominal, 10.4–11.6 V min/max at IZT = 50 mA - defines stable regulation point under typical bias |
| Dynamic Resistance (rzj) | 4–7 Ω at IZT = 50 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pdiss) | 3 W at Tamb = 100 °C with RthJA < 25 K/W - sets maximum continuous power under heatsink-limited conditions |
| Surge Power (PZSM) | 600 W for 100 µs pulse - enables transient overvoltage clamping without failure |
| Temperature Coefficient (TKVZ) | ±0.1 %/K at IZT = 50 mA - quantifies voltage drift per degree Celsius for precision designs |
| Reverse Leakage (IR) | ≤ 4 µA at VR = 8.2 V - ensures minimal quiescent current in standby protection circuits |
| Forward Voltage (VF) | 1.2 V at IF = 0.5 A - relevant for polarity-check or dual-function clamp applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | TVS diode (unidirectional), 11.1 V standoff, 17.5 V clamping at 10 A, 600 W peak power | Designed for transient suppression-not precision regulation; higher clamping voltage reduces regulation accuracy | Select when primary need is surge immunity, not stable DC reference |
| BZX84-C11 | SOT-23 package, 11 V nominal, 350 mW Pdiss, 20 Ω rzj, ±5 % tolerance | Lower power rating and higher impedance limit use to low-current biasing only | Select for space-constrained low-power bias networks where 3 W dissipation is unnecessary |
Compared with SMBJ11A and BZX84-C11, the BZG03C11TR3 uniquely balances precision regulation (±5.5 % VZ, 4–7 Ω rzj) with high-power handling (3 W continuous, 600 W surge), making it optimal for industrial and automotive shunt reference and clamp roles requiring both stability and ruggedness.

FAQ
What is the zener voltage tolerance of BZG03C11TR3?
The BZG03C11TR3 has a zener voltage specification of 10.4 V minimum to 11.6 V maximum at 50 mA test current, corresponding to ±5.5 % tolerance around the nominal 11 V rating. This tolerance is confirmed in the Electrical Characteristics table of Vishay Document Number 85593, Rev. 1.7. The BZG03C11TR3 achieves this tight spread through process-controlled junction doping and glass passivation.
Can BZG03C11TR3 be used in reflow soldering processes?
Yes, the BZG03C11TR3 is qualified for both wave and reflow soldering per its mechanical data and packaging specifications. Its DO-214AC package and Pb-free construction comply with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles. The BZG03C11TR3 withstands peak temperatures up to 260 °C for 10 seconds without degradation.
What is the maximum junction temperature for BZG03C11TR3?
The absolute maximum junction temperature for BZG03C11TR3 is 150 °C, as specified in the Absolute Maximum Ratings section of Vishay's datasheet (Document Number 85593). Operation above this temperature risks irreversible parametric shift or junction failure. Derating curves in Figure 2 confirm safe operation up to 100 °C ambient when mounted on Al2O3 ceramic with RthJA = 100 K/W.
How does the dynamic resistance of BZG03C11TR3 affect regulation accuracy?
The BZG03C11TR3 exhibits 4–7 Ω dynamic resistance at 50 mA, directly impacting load regulation: a 10 mA change in zener current causes ~40–70 mV output shift. This low rzj enables tighter voltage control than general-purpose Zeners (e.g., >20 Ω), making the BZG03C11TR3 suitable for precision biasing where regulation stability under varying load is essential.
Is BZG03C11TR3 compliant with RoHS and lead-free requirements?
Yes, the BZG03C11TR3 is explicitly stated as a lead (Pb)-free component and compliant with RoHS Directive 2002/95/EC and WEEE Directive 2002/96/EC per Vishay's documentation. The "e3" marking on the device denotes matte tin termination, and the entire BZG03C-Series manufacturing process excludes ozone-depleting substances and hazardous materials per Vishay's environmental policy.
