Product details
Overview
HZM10NB1TR-E 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, with dynamic resistance ≤30 Ω, power dissipation of 200 mW, and operates within –55°C to +150°C storage range. It is commonly used in voltage regulation for sensor signal conditioning and microcontroller reference supplies.
For engineers reviewing the HZM10NB1TR-E datasheet, HZM10NB1TR-E pinout, HZM10NB1TR-E application, or HZM10NB1TR-E equivalent, key selection criteria include zener voltage tolerance (±2.1% at 10.66 V nominal), low dynamic impedance for stable regulation under load variation, MPAK surface-mount package compatibility with high-density PCB layouts, and thermal stability across industrial temperature ranges.
Technical Context
The HZM10NB1TR-E employs a silicon epitaxial planar junction structure optimized for tight zener voltage control and low temperature coefficient (≈+0.045 mV/°C near 10 V). Its design targets stable DC reference generation where low noise and minimal drift are critical.
It operates with reverse-biased conduction only - no forward rectification function - and requires external current limiting. The device is rated for 2 mA minimum test current and 5 mA typical operating current, with absolute maximum junction temperature of 150°C and pulse-tested dynamic resistance specification.
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 loops and references. |
| Dynamic Resistance (rd) | ≤30 Ω at IZ = 5 mA - ensures minimal output voltage shift under varying load current. |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal derating. |
| Reverse Current (IR) | ≤2 μA at VR = 7.0 V - guarantees low leakage in standby or high-impedance bias networks. |
| Junction Temperature (Tj) | 150°C maximum - supports operation in thermally constrained industrial environments. |
| Temperature Coefficient (γZ) | +0.045 mV/°C (typ.) - enables predictable, low-drift behavior over –25°C to +85°C ambient range. |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), surface-mount, 3-terminal plastic package with 1.0 mm × 1.3 mm footprint and 0.55 mm terminal pitch. Compatible with standard reflow profiles and high-speed pick-and-place assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding required. |
| 2 | Anode | Connected to lower-potential side of bias network; current enters here in reverse breakdown mode. |
| 3 | Cathode | Connected to higher-potential side; zener voltage appears between Cathode and Anode when reverse biased. |
Key Features
| Feature | Design Value |
|---|---|
| Grade B1 voltage tolerance | ±2.1% (10.44–10.88 V) - enables tighter system-level reference accuracy without trimming. |
| Low dynamic impedance | ≤30 Ω - maintains regulation stability under ±1 mA load transients in analog front-ends. |
| MPAK surface-mount package | 0.55 mm pin pitch, 1.0 mm × 1.3 mm body - supports >3000 components/in² board density. |
| High junction temperature rating | 150°C max - allows placement near heat-generating ICs without derating concerns. |
| Low leakage current | ≤2 μA at 7.0 V - preserves battery life and minimizes error in high-impedance voltage dividers. |
Applications
| Industrial Sensor Reference | Microcontroller ADC Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | Zener voltage 9.4–10.6 V (±5%), rd ≤30 Ω, SOT-23 package, Pd = 300 mW | Wider VZ tolerance; higher power rating but larger footprint (SOT-23 vs. MPAK) | Preferred where higher power margin is needed and board space permits larger package. |
| MMSZ4689T1G | Zener voltage 10.0–11.2 V (±5%), rd ≤30 Ω, SOD-123 package, Pd = 500 mW | Looser grading, higher Pd, different thermal profile; not MPAK-compatible | Selected when cost sensitivity outweighs voltage precision and ultra-compact layout requirements. |
Compared with BZX84-C10LT1G and MMSZ4689T1G, the HZM10NB1TR-E offers superior voltage accuracy (±2.1% vs. ±5%) and smallest footprint (MPAK), making it optimal for space-constrained, high-precision analog designs - though its 200 mW rating requires careful thermal management in sustained-load scenarios.

FAQ
What is the exact zener voltage range for HZM10NB1TR-E at 5 mA?
The HZM10NB1TR-E has a guaranteed zener voltage range of 10.44 V to 10.88 V when tested at IZ = 5 mA and Ta = 25°C. This corresponds to Grade B1 binning per Renesas R07DS0358EJ0600 Rev.6.00, with a nominal value of 10.66 V. The tolerance is ±2.1%, tighter than standard Grade B or B2 variants of the same series.
Is pin 1 of HZM10NB1TR-E electrically connected?
No - pin 1 of the HZM10NB1TR-E is designated NC (No Connect) and is internally unconnected. Per the official pin arrangement diagram in the Renesas datasheet, only pins 2 (Anode) and 3 (Cathode) are functional. Pin 1 must remain unconnected on the PCB; routing or grounding it may compromise reliability or violate package mechanical integrity.
What is the maximum reverse current specification for HZM10NB1TR-E?
The maximum reverse current (IR) for HZM10NB1TR-E is 2 μA, measured at VR = 7.0 V and Ta = 25°C. This low leakage supports high-impedance bias networks and extends battery life in always-on monitoring circuits. The value is confirmed in the Electrical Characteristics table on page 3 of the Renesas preliminary datasheet R07DS0358EJ0600.
Can HZM10NB1TR-E be used in place of a TL431 shunt regulator?
The HZM10NB1TR-E cannot directly replace a TL431 because it lacks active feedback, adjustable reference, or current-sinking capability - it is a passive two-terminal zener. However, it serves as a simpler, lower-cost, lower-quiescent alternative where fixed 10.66 V regulation suffices and external current limiting is acceptable. System redesign is required to accommodate its non-adjustable, non-amplified behavior.
What is the thermal derating behavior of HZM10NB1TR-E above 25°C ambient?
HZM10NB1TR-E follows linear thermal derating from 200 mW at Ta = 25°C down to 0 mW at Ta = 150°C, as shown in Figure 3 of the Renesas datasheet. The derating slope is –1.82 mW/°C. At 85°C ambient, maximum allowable power drops to approximately 91 mW - requiring corresponding reduction in bias current to avoid exceeding junction temperature limits.
