Product details
Overview
HZM10NB2JTR-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 test current, 7.0 Ω dynamic resistance, and 200 mW power dissipation in MPAK (SC-59A) package - used in power supply feedback loops and sensor biasing.
For engineers reviewing the HZM10NB2JTR-E datasheet, HZM10NB2JTR-E pinout, HZM10NB2JTR-E application, or HZM10NB2JTR-E equivalent, key selection criteria include zener voltage tolerance (±2.2% at grade B2), temperature coefficient (≈+0.045 mV/°C near 10 V), low leakage (<2 µA at 8.0 V), thermal stability up to 150°C junction temperature, and compatibility with high-density SMT assembly.
Technical Context
The HZM10NB2JTR-E operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its specified breakdown threshold. Its epitaxial planar structure ensures tight VZ distribution and low noise performance critical for reference applications.
Designed for surface-mount use in the MPAK (PLSP0003ZC-A / SC-59A) package, it features a non-connected (NC) terminal (Pin 1), anode (Pin 2), and cathode (Pin 3) - enabling compact layout while supporting pulse-tested operation (Pw = 40 ms) per absolute maximum ratings.
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 feedback networks and voltage references. |
| Dynamic Resistance (rd) | 7.0 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load transients. |
| Reverse Current (IR) | ≤2 µA at VR = 8.0 V - guarantees low standby power loss in battery-backed or energy-sensitive designs. |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets thermal derating limit for PCB trace width and copper area planning. |
| Junction Temperature (Tj) | –55 to +150°C - supports operation in industrial and automotive under-hood environments without external heatsinking. |
| Temperature Coefficient (γZ) | +0.045 mV/°C (typ.) near 10 V - enables predictable drift compensation in precision analog stages. |
| Package | MPAK (SC-59A, JEITA PLSP0003ZC-A) - 3-pin SMT footprint with 0.65 mm lead pitch, optimized for automated placement. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC (No Connection) | Electrically isolated terminal - must remain unconnected on PCB to avoid parasitic coupling or mechanical stress. |
| 2 | Anode | Connected to lower-potential node (e.g., ground or return path); reverse-biased during regulation. |
| 3 | Cathode | Connected to higher-potential node (e.g., input rail); supplies regulated voltage to load via current sink. |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B2 zener voltage tolerance | ±2.2% (10.11–10.55 V) - reduces calibration overhead in factory-trimmed instrumentation. |

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 (ON Semiconductor) | 10 V nominal, ±5% tolerance (grade C), 20 Ω rd, SOT-23 package (smaller footprint, no NC pin) | Lacks NC pin; higher dynamic resistance increases regulation error in precision feedback paths. | Preferred for cost-sensitive consumer designs where ±5% VZ and 20 Ω rd are acceptable. |
| MMSZ5240B-TP (Micro Commercial Components) | 10 V nominal, ±5% tolerance, 17 Ω rd, SOD-123 package (higher thermal resistance than MPAK) | Higher junction-to-ambient θJA (450°C/W vs. ~300°C/W for MPAK) limits continuous power in confined layouts. | Suitable for low-duty-cycle clamping where thermal constraints dominate over voltage precision. |
Compared with BZX84-C10LT1G and MMSZ5240B-TP, the HZM10NB2JTR-E delivers tighter VZ tolerance (±2.2%), lower rd (7.0 Ω), and integrated NC pin for mechanical stability - making it optimal for industrial feedback and medical-grade references where regulation accuracy and long-term drift matter most.

FAQ
What is the exact zener voltage range for HZM10NB2JTR-E at 5 mA test current?
The HZM10NB2JTR-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, corresponding to grade B2 tolerance (±2.2%). This specification is confirmed in the Electrical Characteristics table on page 3 of R07DS0358EJ0600 Rev.6.00 and applies directly to the HZM10NB2JTR-E variant.
Does HZM10NB2JTR-E have a pin 1 NC connection, and why is it included?
Yes, HZM10NB2JTR-E features Pin 1 as NC (no connection), clearly shown in the "Pin Arrangement" diagram on page 1 of the datasheet. This terminal is electrically isolated and mechanically present to improve package rigidity and alignment during high-speed SMT placement - it must not be soldered or tied to any net on the PCB to avoid stress-induced parameter shift.
What is the maximum power dissipation rating for HZM10NB2JTR-E, and how does it derate with temperature?
HZM10NB2JTR-E has a maximum power dissipation (Pd) of 200 mW at Ta = 25°C, as stated in the Absolute Maximum Ratings table (page 2). Derating follows the curve in Fig. 3: linear reduction begins at ~50°C ambient, reaching zero dissipation at ~150°C. Designers must calculate board copper area and thermal vias based on actual layout to maintain safe junction temperature.
Is HZM10NB2JTR-E suitable for automotive applications, and what quality grade does it carry?
HZM10NB2JTR-E is classified as "Standard" quality grade per Renesas' documentation (page 6, Note 7), intended for industrial, office, and communications equipment - not rated for automotive safety-critical systems. While its 150°C junction rating meets under-hood temperature requirements, it lacks AEC-Q200 qualification and is not approved for use in engine control or ADAS subsystems.
How does the temperature coefficient of HZM10NB2JTR-E compare to other 10 V Zeners, and where is this value documented?
The HZM10NB2JTR-E exhibits a typical temperature coefficient (γZ) of +0.045 mV/°C near 10 V, derived from Fig. 2 ("Temperature Coefficient vs. Zener Voltage") on page 5 of R07DS0358EJ0600 Rev.6.00. This value is lower than many generic 10 V Zeners (which often exceed ±0.1 mV/°C), contributing to superior thermal stability in precision analog circuits using the HZM10NB2JTR-E.
