Product details
Overview
HZM10NB1JTL from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits. It delivers a nominal zener voltage of 10.44 V to 10.88 V at 5 mA test current, with dynamic resistance of 7.0 Ω max and reverse current ≤2 μA at 7.0 V, housed in the compact MPAK (SC-59A) surface-mount package.
For engineers reviewing the HZM10NB1JTL datasheet, HZM10NB1JTL pinout, HZM10NB1JTL application, or HZM10NB1JTL equivalent, this device serves as a stable, temperature-compensated voltage reference in power supply feedback loops, sensor biasing networks, and overvoltage protection clamps where tight tolerance and low dynamic impedance are critical.
Technical Context
The HZM10NB1JTL operates as a two-terminal shunt regulator, maintaining a stable output voltage across its cathode-anode terminals when reverse-biased above its specified zener breakdown threshold. Its graded B1 tolerance ensures ±2.1% zener voltage accuracy at 5 mA, and its temperature coefficient is +0.04 mV/°C near 10 V - enabling predictable drift behavior in ambient-temperature-varying environments.
Designed for high-density PCB assembly, the device uses an epitaxial planar process to achieve low leakage (IR ≤2 μA at VR = 7.0 V), low dynamic resistance (rd ≤7.0 Ω), and robust thermal performance up to 150°C junction temperature. It is not intended for surge suppression or transient clamping beyond its 200 mW absolute maximum power dissipation rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.44 V to 10.88 V at IZ = 5 mA - defines precise regulation point for feedback or reference use |
| Dynamic Resistance (rd) | ≤7.0 Ω at IZ = 5 mA - ensures minimal output voltage variation under load current changes |
| Reverse Current (IR) | ≤2 μA at VR = 7.0 V - guarantees low standby leakage in battery-sensitive or high-impedance bias networks |
| Power Dissipation (Pd) | 200 mW max at Ta = 25°C - sets thermal design limit for continuous DC operation on standard FR-4 PCB |
| Junction Temperature (Tj) | –55°C to +150°C - supports industrial-grade operation without derating below –40°C or above +85°C ambient |
| Temperature Coefficient (γZ) | +0.04 mV/°C - enables predictable, low-drift voltage reference behavior near 10 V nominal |
Pinout & Package
The HZM10NB1JTL is packaged in the MPAK (JEITA code PLSP0003ZC-A, equivalent to SC-59A), a 3-pin surface-mount plastic package measuring 2.7 × 1.35 × 0.95 mm (L × W × H), optimized for automated pick-and-place and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding permitted |
| 2 | Anode | Forward-bias terminal; connects to lower-potential node in shunt regulation configuration |
| 3 | Cathode | Zener breakdown terminal; connects to regulated voltage node and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| Graded B1 Zener Tolerance | ±2.1% voltage accuracy at 5 mA - reduces calibration overhead in precision analog designs |
| Low Dynamic Resistance | ≤7.0 Ω - maintains regulation stability under varying load or line conditions |
| MPAK Surface-Mount Package | SC-59A footprint (2.7 × 1.35 mm) - enables high-density layout and compatibility with standard 0805-class placement equipment |
| Controlled Temperature Drift | +0.04 mV/°C near 10 V - supports stable reference performance across –40°C to +85°C operating range |
| Low Reverse Leakage | ≤2 μA at 7.0 V - minimizes error in high-impedance voltage divider or sensor bias applications |
Applications
| Industrial Power Supply Feedback | Portable Sensor Biasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G (onsemi) | 10 V nominal, ±5% tolerance (C grade), 15 Ω rd, SOT-23 package | Loose tolerance and higher dynamic resistance - suitable for non-critical biasing, not precision regulation | Select when cost sensitivity outweighs voltage accuracy; verify thermal margin due to 350 mW Pd but smaller pad thermal mass |
| MMSZ5240B-TP (Micro Commercial Components) | 10 V nominal, ±5% tolerance, 17 Ω rd, SOD-123 package | Higher rd and wider VZ spread - acceptable for general-purpose clamping but not for feedback loops requiring <1% error | Choose for legacy SOD-123 layouts; note 500 mW Pd rating requires careful trace width design to avoid overheating |
Compared with BZX84-C10LT1G and MMSZ5240B-TP, the HZM10NB1JTL offers tighter B1-grade voltage tolerance (±2.1%), lower dynamic resistance (7.0 Ω), and a thermally optimized MPAK package - making it preferable for closed-loop regulation and high-accuracy biasing where stability and repeatability are design-critical.

FAQ
What is the exact zener voltage range for HZM10NB1JTL at 5 mA?
The HZM10NB1JTL has a guaranteed zener voltage range of 10.44 V to 10.88 V when tested at IZ = 5 mA and Ta = 25°C, per its B1 grade specification in the Renesas R07DS0358EJ0600 datasheet. This 4.4% total span reflects tight manufacturing control for applications demanding repeatable regulation points without post-assembly trimming.
Is Pin 1 of HZM10NB1JTL electrically connected internally?
No - Pin 1 of the HZM10NB1JTL is designated NC (No Connect) and is internally unconnected. The device functions as a two-terminal Zener diode using only Pins 2 (Anode) and 3 (Cathode). Pin 1 must remain unconnected on the PCB; routing or grounding it may compromise reliability or violate package mechanical integrity.
What is the maximum power dissipation of HZM10NB1JTL and how does it derate with temperature?
The HZM10NB1JTL has an absolute maximum power dissipation of 200 mW at Ta = 25°C, linearly derating to zero at 150°C junction temperature. Derating follows the curve in Figure 3 of the datasheet: approximately 1.6 mW/°C above 25°C ambient on standard FR-4 with 1.6 mm copper foil, requiring thermal relief design for sustained >150 mW operation.
Can HZM10NB1JTL be used as a substitute for a 10 V Zener in legacy through-hole designs?
The HZM10NB1JTL is a surface-mount MPAK (SC-59A) device and is not a direct physical replacement for through-hole Zeners like the 1N4740A. While its electrical function is equivalent, PCB layout redesign is required to accommodate its 2.7 × 1.35 mm footprint and 3-pin configuration (including NC pin). Electrical substitution is viable only after verifying thermal, layout, and tolerance compatibility.
What is the reverse leakage current specification for HZM10NB1JTL at 7.0 V?
The HZM10NB1JTL specifies a maximum reverse current (IR) of 2 μA when biased at VR = 7.0 V and Ta = 25°C. This low leakage supports high-impedance applications such as RTD biasing or precision voltage dividers where error contribution from diode current must remain below 0.1% of signal chain full-scale.
