Product details
Overview
5962R0051601VHA from Analog Devices is a radiation-hardened, monolithic silicon precision voltage reference delivering +5 V output with ±0.03% initial accuracy, 8.5 ppm/°C temperature coefficient, and 15 µVP-P (0.1–10 Hz) output noise - deployed in military avionics power monitoring and spacecraft telemetry conditioning circuits.
For engineers reviewing the 5962R0051601VHA datasheet, 5962R0051601VHA pinout, 5962R0051601VHA application, or 5962R0051601VHA equivalent, key selection criteria include radiation tolerance (50 krad(Si) at low dose rate), adjustable output via external trim resistor, operation across –55°C to +125°C, and compliance with MIL-PRF-38535 Class V requirements.
Technical Context
This device implements a bandgap-based reference core with internal trimming capability, enabling precise adjustment of output voltage over ±3.0% using an external 10 kΩ potentiometer connected to the TRIM terminal. It operates with input voltages from 8 V to 33 V and delivers stable output under load currents up to 10 mA.
The 5962R0051601VHA features indefinite short-circuit protection, sink current capability of –0.3 mA, and thermal resistance of 180°C/W (junction-to-ambient) in its flat-pack H outline. Its long-term stability is rated at 100 ppm per 1,000 hours at 76°C chip temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.985–5.015 V at TA = –55°C to +125°C, IL = 0 mA - ensures tight regulation for ADC/DAC biasing in harsh environments. |
| Tempco | 8.5 ppm/°C - limits drift to <±1.5 mV over full military temperature range, critical for precision sensor signal chains. |
| Output Noise | 15 µVP-P (0.1–10 Hz) - supports low-noise instrumentation amplifier references without added filtering. |
| Radiation Tolerance | 50 krad(Si) total ionizing dose (low dose rate ≤10 mrad/s) - qualified for satellite subsystems exposed to prolonged space radiation. |
| Quiescent Current | 1.4 mA max - enables low-power operation in battery-backed telemetry modules. |
| Line Regulation | 0.01 %/V (VIN = 8–33 V) - maintains accuracy despite wide-input DC-DC converter ripple or bus transients. |
| Load Regulation | 0.01 %/mA (IL = 0–10 mA) - sustains reference integrity across variable sensor excitation loads. |
Pinout & Package
5962R0051601VHA uses the MIL-STD-1835 case outline H (GDFP1-F10 or CDFP2-F10), a 10-terminal hermetic flat-pack package with grounded metal case. Pin 1 is NC; pins 2 (VIN), 4 (GND), 5 (TRIM), 6 (VOUT), and 10 (GND) are active; pins 3 (TEMP), 7–9, and 11–12 are NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connection - electrically isolated; no routing required on PCB. |
| 2 | VIN | Main input supply - accepts 8–33 V DC; must be decoupled within 1 cm of pin. |
| 3 | TEMP | Internal die temperature monitor - used for external thermal compensation or fault detection. |
| 4 | GND | Analog ground reference - connects to clean system ground plane; shares pin 10. |
| 5 | TRIM | Adjustment node - connects to center tap of 10 kΩ potentiometer for ±3% output tuning. |
| 6 | VOUT | Regulated +5 V output - drives high-impedance loads (<10 mA); requires local 1 µF ceramic bypass. |
| 7–9, 11–12 | NC | No connection - left unconnected; no thermal or shielding function. |
| 10 | GND | Secondary analog ground - internally tied to pin 4; improves grounding robustness in noisy layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Radiation-hardened design | Qualified to 50 krad(Si) at low dose rate per MIL-STD-883 method 1019 condition D - enables use in LEO and GEO satellite power systems. |
| Adjustable output voltage | ±3.0% trim range via external resistor - allows field calibration to compensate for system-level gain errors without redesign. |
| Wide operating temperature | –55°C to +125°C ambient - meets MIL-PRF-38535 Class V requirements for engine bay and payload bay electronics. |
| Hermetic flat-pack packaging | MIL-STD-1835 outline H (GDFP1-F10) - provides moisture and particle immunity essential for 20+ year space mission lifetimes. |
| Indefinite short-circuit protection | Internally limited output current - prevents latch-up or thermal runaway during wiring faults in distributed power architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962R0051601VGA | Same REF05AL core, but case outline G (8-pin can) - higher θJA (150°C/W) and no TEMP pin. | Limited to lower-power, non-thermal-compensated applications where hermeticity is required but footprint is constrained. | Select when board space is limited and thermal monitoring is unnecessary; avoid for >85°C ambient deployments. |
| 5962R0051601VPA | Same REF05AL core, but case outline P (8-pin CDIP) - θJA = 148°C/W, no TEMP or NC pins beyond standard 4-terminal set. | Suitable for legacy through-hole designs requiring radiation hardness but lacking surface-mount assembly capability. | Choose only for retrofit into existing DIP-8 footprints; not recommended for new high-density layouts due to larger size and lower thermal performance. |
Compared with 5962R0051601VHA, the VGA offers smaller footprint but lacks thermal sensing and has inferior thermal resistance, while the VPA supports through-hole assembly but sacrifices pin count flexibility and thermal management - making the VHA optimal for new SMT-based, thermally aware, radiation-hardened systems.

FAQ
What is the radiation hardness specification for the 5962R0051601VHA?
The 5962R0051601VHA is qualified to 50 krad(Si) total ionizing dose at low dose rate (≤10 mrad(Si)/s), tested per MIL-STD-883 method 1019 condition D. This rating applies specifically to device type 02, which matches the "01" in the PIN's device type field. Post-irradiation electrical parameters remain within table I limits at +25°C.
Does the 5962R0051601VHA require external capacitors for stability?
Yes, the 5962R0051601VHA requires a minimum 1 µF ceramic capacitor between VOUT and GND, placed within 5 mm of the device, to ensure stability under all load conditions. Input bypassing with a 0.1 µF ceramic capacitor near VIN is also mandatory to suppress high-frequency noise and prevent oscillation.
Can the 5962R0051601VHA output voltage be adjusted, and how?
Yes, the 5962R0051601VHA output voltage is adjustable over ±3.0% using an external 10 kΩ potentiometer connected between VOUT and GND, with its wiper tied to the TRIM pin. This allows fine-tuning to compensate for system-level gain errors or aging effects without modifying the PCB layout.
What is the maximum allowable input voltage for the 5962R0051601VHA?
The absolute maximum input voltage for the 5962R0051601VHA is 40 V DC. However, the recommended operating input voltage is +15 V, and line regulation is specified over 8 V to 33 V. Exceeding 33 V may degrade long-term stability and increase self-heating beyond design margins.
Is the 5962R0051601VHA pin-compatible with commercial-grade REF05AL devices?
No, the 5962R0051601VHA is not pin-compatible with commercial REF05AL variants. It uses MIL-STD-1835 outline H (10-pin flat pack) with dedicated TEMP and dual GND pins, whereas commercial REF05AL typically uses SOIC-8 or TO-99 packages. Board redesign is required for substitution.
