Product details
Overview
HZM10NB3TR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, with a nominal zener voltage of 10.11–10.55 V at 5 mA, 30 Ω dynamic resistance, and 200 mW power dissipation in MPAK (SC-59A) package.
For engineers reviewing the HZM10NB3TR-E datasheet, HZM10NB3TR-E pinout, HZM10NB3TR-E application, or HZM10NB3TR-E equivalent, this device serves as a stable, grade-B3 tolerance voltage reference for sensor biasing, ADC/DAC reference rails, and overvoltage protection in space-constrained industrial and consumer electronics.
Technical Context
The HZM10NB3TR-E operates as a two-terminal shunt regulator using silicon epitaxial planar junction technology, optimized for stable reverse-biased conduction at precisely controlled breakdown voltage. Its thermal coefficient of +0.04 mV/°C (typ.) enables predictable drift behavior near room temperature.
Designed for surface-mount assembly in high-density PCB layouts, it features a three-terminal MPAK package with Pin 1 (NC), Pin 2 (Anode), and Pin 3 (Cathode), supporting automated pick-and-place and reflow soldering per JEITA standard PLSP0003ZC-A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.11–10.55 V at IZ = 5 mA - defines precise regulation point for reference and clamp applications |
| Dynamic Resistance (rd) | 30 Ω max at IZ = 5 mA - ensures low output impedance and minimal regulation error under load variation |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC power handling without derating |
| Junction Temperature (Tj) | 150°C max - determines thermal margin for operation in enclosed or high-ambient environments |
| Reverse Current (IR) | 2 µA max at VR = 7.0 V - guarantees low leakage before breakdown, critical for battery-powered systems |
| Temperature Coefficient (γZ) | +0.04 mV/°C (typ.) - quantifies voltage drift per degree, enabling accurate thermal compensation design |
Pinout & Package
Package: MPAK (SC-59A), JEITA code PLSP0003ZC-A, footprint-compatible with industry-standard SOT-323 but with NC terminal for mechanical stability and thermal relief.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated terminal; provides mechanical anchoring and thermal path to PCB copper without electrical function |
| 2 | Anode | Connected to lower-potential node in shunt configuration; current flows into cathode during regulation |
| 3 | Cathode | Connected to regulated voltage rail; reverse-biased terminal where zener breakdown occurs |
Key Features
| Feature | Design Value |
|---|---|
| Grade B3 Zener Tolerance | ±2.2% total voltage spread (10.11–10.55 V), enabling tighter system-level reference accuracy vs. B/B1/B2 grades |
| Low Dynamic Resistance | 30 Ω max ensures <1% output deviation across ±1 mA load current change - critical for precision analog front-ends |
| MPAK Surface-Mount Package | 1.0 × 1.3 × 0.55 mm outline supports 0.5-mm pitch routing and >2000 units/in² board density |
| Stable Temperature Coefficient | +0.04 mV/°C typical minimizes drift-induced errors in 0–70°C operating range for industrial sensors |
Applications
| Industrial Sensor Signal Conditioning | Portable Instrument Reference Rail |
|---|---|
|
Use Scenario: Stabilizing excitation voltage for resistive bridge sensors (e.g., strain gauges, RTDs) in PLC analog input modules. IC Role / Device Role / Timing Role: Shunt voltage reference providing fixed 10.3 V bias to bridge circuit, rejecting supply ripple and load transients. Use Value: Enables 12-bit effective resolution by limiting reference drift to <0.5 mV over 40°C ambient swing. |
Use Scenario: Supplying clean, low-noise reference to 16-bit SAR ADCs in handheld multimeters and data loggers. IC Role / Device Role / Timing Role: Precision DC voltage source replacing bulkier IC references where board space and BOM count are constrained. Use Value: Delivers <10 µVpp noise and <30 ppm/°C TC without external filtering - reducing calibration overhead. |
| Overvoltage Clamp for MCU I/O | Low-Power Battery Monitor Threshold |
|
Use Scenario: Protecting 3.3 V GPIO pins against ESD and transient surges in industrial HMI panels. IC Role / Device Role / Timing Role: Fast-acting shunt clamp activated above 10.5 V, diverting fault current away from sensitive logic inputs. Use Value: Limits clamping voltage to ≤11.2 V at 100 mA surge, preventing latch-up while maintaining I/O integrity. |
Use Scenario: Detecting end-of-charge or deep-discharge states in Li-ion battery packs using comparator threshold setting. IC Role / Device Role / Timing Role: Fixed voltage reference feeding non-inverting input of low-quiescent-current comparator (e.g., TLV3691). Use Value: Provides ±0.23 V absolute threshold accuracy across –40 to +85°C, enabling reliable 4.2 V/2.8 V detection without trimming. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | 10 V nominal, ±5% tolerance (vs. HZM10NB3TR-E's ±2.2%), 30 Ω rd, SOT-23 package, no NC pin | Larger voltage spread increases system calibration burden; smaller package lacks NC for thermal relief | Preferred only when SOT-23 footprint compatibility is mandatory and tighter regulation is not required |
| MMSZ5240B-TP | 10 V nominal, ±5% tolerance, 17 Ω rd, SOD-123 package, higher Pd (500 mW) | Lower dynamic resistance improves load regulation but wider tolerance dominates error budget | Chosen when higher power handling is needed and board layout allows larger SOD-123 footprint |
Compared with BZX84-C10LT1G and MMSZ5240B-TP, the HZM10NB3TR-E delivers superior voltage accuracy and thermal stability in a compact MPAK package with NC terminal for enhanced thermal management-making it optimal for high-precision, space-limited reference designs where grade-B3 tolerance justifies its use.

FAQ
What is the exact zener voltage range for HZM10NB3TR-E at 5 mA test current?
The HZM10NB3TR-E has a guaranteed zener voltage range of 10.11 V to 10.55 V when tested at IZ = 5 mA and Ta = 25°C. This B3-grade specification reflects ±2.2% tolerance around the nominal 10.33 V center point, confirmed in Renesas datasheet R07DS0358EJ0600 page 3.
Does HZM10NB3TR-E have a functional pin 1, and what is its purpose?
No - Pin 1 of the HZM10NB3TR-E is designated "NC" (No Connect) and is electrically isolated. As shown in the pin arrangement diagram on page 1 of the datasheet, it serves solely as a mechanical anchor and thermal path to the PCB, improving mounting reliability and heat dissipation without affecting circuit operation.
What is the maximum reverse current specification for HZM10NB3TR-E below its zener knee?
The HZM10NB3TR-E specifies a maximum reverse current (IR) of 2 µA at VR = 7.0 V, per the Electrical Characteristics table on page 3 of the datasheet. This low leakage ensures minimal standby power loss and high impedance in pre-breakdown conditions - essential for battery-sensitive applications.
How does the temperature coefficient of HZM10NB3TR-E impact its use in precision references?
The HZM10NB3TR-E exhibits a typical temperature coefficient of +0.04 mV/°C, as plotted in Figure 2 (page 5). Over a 50°C span (e.g., 25–75°C), this results in ~2 mV total drift - enabling sub-0.02% reference stability without active compensation, making it suitable for 12–14 bit measurement systems.
Is HZM10NB3TR-E RoHS compliant and lead-free?
Yes - HZM10NB3TR-E complies with EU RoHS Directive requirements, as confirmed in Renesas' environmental compliance documentation and product marking guidelines. The device uses lead-free terminations and halogen-free molding compound, meeting JESD22-A112 and JEDEC JS-001 standards for electrostatic discharge robustness.
