Product details
Overview
SMB10J16HE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on power 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 and industrial motor drives to protect MOSFETs and microcontrollers from inductive switching transients.
For engineers reviewing the SMB10J16HE3/52 datasheet, SMB10J16HE3/52 pinout, SMB10J16HE3/52 application, or SMB10J16HE3/52 equivalent, key selection criteria include clamping performance under 10/1000 μs surges, AEC-Q101 qualification for automotive use, RoHS-compliant HE3 suffix with JESD 201 Class 2 whisker resistance, and thermal resistance (RθJA = 72 °C/W) for surface-mount thermal management on 5.0 mm × 5.0 mm copper pads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (17.8–19.7 V), it avalanches to limit transient energy across protected circuit nodes. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response (<1 ns), while low incremental surge resistance enables effective clamping during 8.3 ms half-sine surges up to 100 A IFSM.
The device is rated for -55 °C to +150 °C junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards - confirming suitability for automated SMT assembly in high-reliability automotive and industrial PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC/AC working margin for protected line. |
| VBR (min/max) | 17.8 V / 19.7 V - breakdown threshold range at 1.0 mA test current; ensures reliable turn-on above VWM with process tolerance. |
| VC @ IPPM | 26.0 V at 38.5 A - clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream ICs like MCUs or gate drivers. |
| PPPM | 1000 W - peak pulse power handling with 10/1000 μs waveform; quantifies single-event surge energy absorption capability. |
| RθJA | 72 °C/W - junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; guides PCB copper area requirements for thermal reliability. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for under-hood and body-control modules. |
| RoHS / Whisker | RoHS-compliant HE3 suffix with JESD 201 Class 2 whisker resistance - ensures long-term solder joint integrity in high-humidity environments. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, molded plastic case with cathode band marking; dimensions 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration; conducts during forward surge events. |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail or sensor input); avalanches into conduction when reverse voltage exceeds VBR to clamp transients. |
Key Features
| Feature | Design Value |

Use Value: Fast <1 ns response and 26.0 V clamping ensure sensor output stays within ADC input range during transient events, avoiding firmware resets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/52 | Same DO-214AA package and 16 V VWM, but not AEC-Q101 qualified; RθJA = 75 °C/W vs. 72 °C/W; no JESD 201 Class 2 whisker rating. | Approved for commercial/industrial use only; unsuitable for automotive production due to missing AEC-Q101 validation. | Select SMBJ16A-E3/52 only for cost-sensitive non-automotive designs where qualification is not mandated. |
| 1.5SMC16A | Higher-power SMC package (1500 W PPPM), larger footprint (7.11 mm × 6.22 mm); VBR 17.8–19.7 V same, but VC = 26.5 V at 42.5 A. | Requires PCB layout change; better suited for high-energy industrial mains protection where space allows. | Choose 1.5SMC16A when surge energy exceeds 1000 W or thermal budget permits larger pad area for lower RθJA (40 °C/W). |
Compared with SMBJ16A-E3/52, SMB10J16HE3/52 adds AEC-Q101 qualification and enhanced whisker resistance for automotive deployment; versus 1.5SMC16A, it trades power headroom for compact DO-214AA footprint and tighter thermal design in space-constrained modules.

FAQ
What is the clamping voltage of SMB10J16HE3/52 and how is it measured?
The SMB10J16HE3/52 has a maximum clamping voltage (VC) of 26.0 V, measured at a peak pulse current (IPPM) of 38.5 A using the standardized 10/1000 μs double-exponential surge waveform. This value represents the highest voltage that appears across the SMB10J16HE3/52 during such a transient event, directly limiting stress on downstream components like microcontrollers or gate drivers.
Is SMB10J16HE3/52 suitable for automotive applications?
Yes, SMB10J16HE3/52 is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS compliance plus JESD 201 Class 2 whisker resistance - making it approved for under-hood and body-control module use in production automotive systems. Its -55 °C to +150 °C operating range and validated surge performance align with ISO 7637-2 requirements.
How does the HE3 suffix differ from E3 in SMB10J16HE3/52?
The HE3 suffix in SMB10J16HE3/52 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS compliance only (no automotive qualification). Both share the same DO-214AA package and electrical specs, but SMB10J16HE3/52 is certified for automotive production, while SMB10J16E3/52 is limited to commercial/industrial use.
What is the thermal resistance of SMB10J16HE3/52 and why does it matter?
SMB10J16HE3/52 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 determines how much the junction temperature rises under power dissipation - critical for ensuring SMB10J16HE3/52 remains within its 150 °C max TJ limit during repeated surge events in enclosed enclosures.
Can SMB10J16HE3/52 be used for bidirectional protection?
No, SMB10J16HE3/52 is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection, Vishay offers the SMB8J16CA variant (same VWM and clamping but symmetrical breakdown). Using SMB10J16HE3/52 in reverse-biased configurations risks failure during positive transients on the anode side.
