Product details
Overview
V62/11615-01XE from Texas Instruments is a precision 2.5 V shunt voltage reference in SOT-23-3 (DBZ) package, featuring ±0.65% initial tolerance, 100 ppm/°C max temperature coefficient, 35 μVRMS typical noise, and operation across –55°C to 125°C. It delivers stable reference voltage for high-accuracy analog signal chains in aerospace-grade power-supply monitors and data-acquisition systems.
For engineers reviewing the V62/11615-01XE datasheet, V62/11615-01XE pinout, V62/11615-01XE application, or V62/11615-01XE equivalent, key selection criteria include cathode current range (45 μA–15 mA), dynamic impedance (0.3 Ω typ at 120 Hz), thermal hysteresis (0.08%), long-term stability (120 ppm), and compatibility with all capacitive loads without external compensation.
Technical Context
The V62/11615-01XE implements a Zener-based shunt reference architecture trimmed via Zener-zap during wafer sort, enabling tight 2.5 V output tolerance. Its two-terminal topology requires no external capacitor for stability and maintains low dynamic impedance (<1 Ω) across 10 Hz–100 kHz.
Designed for extended-life military/aerospace use, it operates over full –55°C to 125°C ambient range with controlled baseline, single-fab fabrication, and traceable lot marking. The DBZ package integrates a parasitic Schottky diode between pins 2 and 3, mandating pin 3 be left open or tied to pin 2 (anode).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5 V nominal; enables direct interface with 2.5 V ADC references and DAC feedback loops. |
| Initial Tolerance | ±0.65% at 25°C; ensures ≤16 mV absolute error without calibration in precision sensor front-ends. |
| Temp Coefficient | ±100 ppm/°C max over full range; limits drift to ±250 μV/°C in wide-temperature industrial controls. |
| Cathode Current Range | 45 μA (typ) to 15 mA; supports ultra-low-power battery monitoring and high-current reference buffering. |
| Dynamic Impedance | 0.3 Ω typ at 120 Hz; minimizes AC load-induced voltage perturbation in switching power-supply feedback paths. |
| Output Noise | 35 μVRMS (10 Hz–10 kHz); preserves SNR in 16-bit+ data-acquisition systems without additional filtering. |
| Long-Term Stability | 120 ppm over 1000 h; reduces recalibration frequency in medical instrumentation and test equipment. |
Pinout & Package
SOT-23-3 (DBZ) package: 3-pin surface-mount, 1.12 mm max height, JEDEC TO-236 compliant, with exposed substrate connection on pin 3. Pin 3 must be left open or connected to anode (pin 2) due to internal parasitic Schottky diode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Current sink node; connects to supply rail through series resistor (RS) and to load return path. |
| Pin 2 | Anode | Reference ground node; ties to system ground or negative rail; forms Zener breakdown junction with cathode. |
| Pin 3 | Substrate Tie | Internally connected to die substrate; must be left floating or shorted to pin 2 (anode) - never driven independently. |
Key Features
| Feature | Design Value |
|---|---|
| Stable with all capacitive loads | Eliminates need for output bypass capacitor - simplifies layout and reduces BOM count in space-constrained avionics modules. |
| Low 35 μVRMS noise | Enables <1 LSB error in 16-bit SAR ADCs without post-filtering, critical for precision instrumentation. |
| –55°C to 125°C operation | Qualified for extended military temperature range per MIL-PRF-38535, supporting engine control and satellite payload designs. |
| 0.65% initial accuracy | Meets Class A reference requirements for ISO 13849-compliant safety systems without trimming circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C25MDBZTEP | Same silicon, identical electrical specs, but commercial-temp (–40°C to 125°C) and non-extended product lifecycle. | Lacks defense/aerospace qualification, MIL-PRF-38535 compliance, and controlled baseline documentation. | Select when cost sensitivity outweighs extended temp range and traceability requirements. |
| REF3025AIDBZR | Series reference (not shunt); 2.5 V, ±0.2% initial accuracy, 50 ppm/°C TC, 50 μA quiescent current. | Requires input headroom (~100 mV), incompatible with low-headroom or floating-bus topologies where V62/11615-01XE excels. | Choose only if system design permits series topology and higher accuracy justifies added complexity and cost. |
Compared with LM4040C25MDBZTEP, V62/11615-01XE adds full military temperature range and extended product lifecycle support; compared with REF3025AIDBZR, it offers shunt topology flexibility and lower minimum operating current, but trades off tighter initial tolerance and lower TC.

FAQ
What is the operating temperature range of the V62/11615-01XE?
The V62/11615-01XE is characterized for operation from –55°C to 125°C ambient temperature. This extended range meets MIL-PRF-38535 Class V requirements and supports deployment in aerospace, downhole, and engine-control environments where thermal extremes are routine. The device maintains its ±0.65% initial tolerance and ±100 ppm/°C temperature coefficient across this full range, as verified in TI's production test flow.
Can the V62/11615-01XE be used without an output capacitor?
Yes, the V62/11615-01XE does not require an output capacitor for stability. Its shunt architecture and internal design ensure unconditional stability with all capacitive loads - including 0 μF - eliminating risk of oscillation in sensitive measurement circuits. This feature simplifies PCB layout and reduces component count in compact, high-reliability systems where V62/11615-01XE is deployed.
What is the function of Pin 3 on the V62/11615-01XE in the DBZ package?
Pin 3 on the V62/11615-01XE is internally connected to the silicon substrate and must either be left open or tied directly to Pin 2 (anode). This constraint arises from a parasitic Schottky diode between Pins 2 and 3 in the SOT-23-3 (DBZ) package. Driving Pin 3 independently risks forward-biasing that diode and disrupting regulation, so proper handling is essential for reliable V62/11615-01XE operation.
How does the V62/11615-01XE achieve its 0.65% initial voltage tolerance?
The V62/11615-01XE achieves ±0.65% initial tolerance at 25°C through Zener-zap reverse breakdown voltage trimming performed during wafer sort. This laser-based adjustment targets the precise 2.5 V output across the entire production lot, ensuring consistency without post-package calibration. The tolerance is guaranteed and tested per MIL-PRF-38535 requirements, making V62/11615-01XE suitable for Class A reference applications in safety-critical systems.
Is the V62/11615-01XE RoHS compliant and lead-free?
Yes, the V62/11615-01XE is RoHS compliant with lead finish/NiPdAu (NIPDAU) plating and rated MSL Level-1 (260°C peak reflow). Its packaging meets JEDEC J-STD-020 standards, and the device carries full RoHS certification per TI's published environmental compliance documentation. This ensures compatibility with modern lead-free assembly processes while maintaining reliability in high-integrity V62/11615-01XE deployments.
