Product details
Overview
SMB10J16AHE3_B/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive ECUs, industrial sensor interfaces, and power supply input stages.
For engineers reviewing the SMB10J16AHE3_B/H datasheet, SMB10J16AHE3_B/H pinout, SMB10J16AHE3_B/H application, or SMB10J16AHE3_B/H equivalent, key selection criteria include AEC-Q101 qualification, low clamping ratio (VC/VWM ≈ 1.625), unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents <1.0 µA leakage at 16 V (VWM), then rapidly avalanches when transient voltage exceeds 17.8 V (min VBR), limiting downstream voltage to ≤26.0 V at 38.5 A surge. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Thermally, it sustains operation from –55 °C to +150 °C junction temperature, with RθJA = 72 °C/W (typ.) and RθJL = 20 °C/W (typ.), enabling reliable performance in engine bay or industrial control enclosures. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin. |
| VBR (min/max) | 17.8 V / 19.7 V - breakdown threshold range at 1 mA test current; ensures consistent avalanche initiation across production lot. |
| VC @ IPPM | 26.0 V at 38.5 A - clamped voltage during 10/1000 µs surge; determines maximum stress on protected IC or MOSFET. |
| PPPM | 1000 W - peak pulse power handling with 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity. |
| ID @ VWM | ≤1.0 µA - reverse leakage at rated stand-off voltage; negligible power loss and no thermal runaway risk in standby. |
| TJ max. | +150 °C - maximum junction temperature; enables deployment near heat sources without derating in automotive under-hood designs. |
| Package | SMB (DO-214AA) - surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with standard reflow profiles and J-STD-020 MSL Level 1. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated. Cathode indicated by color band on one end; anode is opposite terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line (e.g., 12 V rail); conducts avalanche current to ground during overvoltage event. |
| Anode | Reference/ground return path | Typically tied to system ground plane; completes shunt path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor modules. |
| Glass passivated junction | Ensures stable VBR over temperature and lifetime; eliminates parameter drift due to moisture or contamination. |
| Low clamping ratio (VC/VWM = 1.625) | Minimizes voltage overshoot on protected circuitry - critical for 16 V-rated microcontrollers and CAN transceivers. |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow assembly without popcorn cracking or delamination risk. |
| 1000 W peak pulse power | Withstands repeated 4 kV IEC 61000-4-5 surges on 12 V/24 V systems without degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/52 | Same VWM (16 V), VBR (17.8–19.7 V), VC (26.0 V), but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy surges (e.g., IEC 61000-4-5 Level 2); not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification or 1000 W surge requirement. |
| 1.5SMC16A | Same electrical specs but in larger SMC (DO-214AB) package; RθJA = 40 °C/W (vs. 72 °C/W), higher thermal mass. | Better thermal robustness in high-ambient environments, but requires larger PCB area and may not fit space-constrained layouts. | Choose when board layout allows SMC footprint and sustained surge duty cycle demands lower junction temperature rise. |
Compared with SMBJ16A-E3/52 and 1.5SMC16A, SMB10J16AHE3_B/H delivers higher surge power rating in a smaller SMB package while maintaining AEC-Q101 compliance - making it optimal for space-limited, high-reliability automotive and industrial power rail protection where 1000 W capability is required.

FAQ
What is the clamping voltage of SMB10J16AHE3_B/H at its rated peak pulse current?
The SMB10J16AHE3_B/H has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current (IPPM) of 38.5 A with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events. The SMB10J16AHE3_B/H maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is SMB10J16AHE3_B/H qualified for automotive applications?
Yes, SMB10J16AHE3_B/H is AEC-Q101 qualified and manufactured with automotive-grade process controls and testing. Its HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified status. The SMB10J16AHE3_B/H is widely used in engine control units, body control modules, and ADAS sensor interfaces where automotive reliability standards apply.
What is the reverse leakage current of SMB10J16AHE3_B/H at its stand-off voltage?
At its 16 V stand-off voltage (VWM), the SMB10J16AHE3_B/H exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C. This ultra-low leakage ensures minimal power loss in always-on circuits and avoids false triggering in high-impedance sensing paths. The SMB10J16AHE3_B/H maintains leakage below 5 µA up to +125 °C ambient.
Does SMB10J16AHE3_B/H have a defined polarity, and how is it marked?
Yes, SMB10J16AHE3_B/H is a unidirectional TVS diode with clearly defined polarity: the cathode is marked by a visible color band on the SMB (DO-214AA) package body. During surge events, current flows from anode to cathode, shunting excess energy to ground. The SMB10J16AHE3_B/H must be oriented correctly in-circuit - reverse installation prevents proper clamping and risks device failure.
What is the thermal resistance of SMB10J16AHE3_B/H, and how does it affect layout?
The SMB10J16AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay specification. To maintain safe junction temperatures under repeated surges, PCB layout must provide adequate copper area and avoid thermal bottlenecks - the SMB10J16AHE3_B/H relies on conduction through leads and pads rather than air convection.
