Product details
Overview
SMBG100HE3/52 from Vishay General Semiconductor is a uni-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR), 162 V maximum clamping voltage (VC) at 3.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBG100HE3/52 datasheet, SMBG100HE3/52 pinout, SMBG100HE3/52 application, or SMBG100HE3/52 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, IFSM surge robustness for automotive load-dump immunity, AEC-Q101 qualification status, and thermal resistance (RθJA = 100 °C/W) for PCB layout derating.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias it presents <1.0 µA reverse leakage at 100 V; during transient overvoltage exceeding VBR (min 111 V), it avalanches to limit voltage across the protected node to ≤162 V. Its glass-passivated junction ensures stable breakdown and low dynamic impedance.
Designed for surface-mount automated placement, SMBG100HE3/52 uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 111 V / 123 V at 1 mA - Confirmed avalanche onset range for reliable turn-on threshold |
| VC @ IPPM | 162 V at 3.7 A - Clamped voltage during 10/1000 µs surge, defining protection window margin |
| PPPM | 600 W - Peak pulse power handling capability with standard 10/1000 µs waveform |
| IFSM | 100 A - Single half-sine surge current rating (8.3 ms), critical for automotive load-dump survival |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance, used to calculate max ambient temperature for 150 °C TJ limit |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
DO-215AA (SMBG) surface-mount package: 2-terminal gull-wing leaded outline, 0.235–0.255 inch body length, cathode band marking on one end. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated PPPM performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-impedance return path; defines polarity for uni-directional clamping |
| Cathode (banded end) | High-side transient input | Connected to protected line (e.g., 12 V rail); avalanche conduction occurs from cathode to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against ISO 7637-2 Pulse 1/2a/5a transients without derating on standard PCB pads |
| AEC-Q101 qualification | Validates suitability for automotive powertrain and body electronics where reliability under thermal stress is mandatory |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without popcorn cracking or delamination |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time), improving clamping fidelity |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Shunt clamping device placed between power rail and chassis ground, activated within <1 ns of overvoltage onset. Use Value: Withstands 100 A IFSM and clamps to ≤162 V, preserving downstream DC-DC converters and microcontrollers rated for 40 V absolute max. |
Use Scenario: Safeguarding analog outputs (e.g., 4–20 mA loops) and digital I/O (CAN, LIN) from ESD and inductive kickback in factory automation PLCs. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF) parallel-connected protector on signal traces, minimizing signal integrity impact. Use Value: 162 V clamping voltage prevents latch-up in op-amps and transceivers while maintaining <1 µA leakage at 100 V operating bias. |
| Telecom Power Feeds | Consumer Power Adapters |
Use Scenario: Input-stage surge suppression on PoE-powered equipment (IEEE 802.3af/at) exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Primary-level uni-directional clamp on DC input, coordinated with upstream GDT or MOV for staged protection. Use Value: 600 W PPPM handles repetitive surges per ITU-T K.20/K.21, and AEC-Q101 grade ensures long-term stability in unventilated enclosures. |
Use Scenario: Secondary-side overvoltage protection in AC/DC adapters for USB-C PD and laptop chargers. IC Role / Device Role / Timing Role: Final-stage TVS on regulated 20 V output, guarding against feedback loop failure or synchronous rectifier shoot-through. Use Value: 100 V VWM aligns with 20 V nominal × 5× safety margin; 162 V VC ensures MOSFETs and controllers remain below their 200 V breakdown limit. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-E3/52 | Same VWM (100 V), identical DO-214AA (SMB) package but 1.6 mm taller; RθJA = 85 °C/W vs. 100 °C/W | Higher power density and slightly better thermal performance; not AEC-Q101 qualified | Select when automotive qualification is unnecessary and board space allows taller profile |
| 1.5KE100A | Through-hole DO-201 package; same VWM/VBR/VC specs but higher IFSM (200 A) and PPPM (1500 W) | Used in legacy industrial power supplies where manual assembly or high-energy surges dominate | Select for non-SMT designs requiring >600 W surge headroom or compatibility with existing through-hole layouts |
Compared with SMBJ100A-E3/52 and 1.5KE100A, SMBG100HE3/52 uniquely combines AEC-Q101 qualification, SMBG's low-profile gull-wing footprint, and optimized thermal design for dense automotive PCBs-making it the preferred choice where space, reliability, and reflow compatibility are jointly constrained.

FAQ
What is the clamping voltage of SMBG100HE3/52 and how is it measured?
The SMBG100HE3/52 has a maximum clamping voltage (VC) of 162 V, measured at a peak pulse current (IPPM) of 3.7 A using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed per the Vishay datasheet (Document Number 88456, page 2) and reflects the voltage across the device terminals during worst-case surge conditions, directly determining protection margin for downstream components.
Is SMBG100HE3/52 suitable for automotive applications?
Yes, SMBG100HE3/52 is AEC-Q101 qualified (per datasheet note on page 3 and ordering table), making it suitable for automotive powertrain, body control, and infotainment systems. Its 100 A IFSM rating supports load-dump immunity, and its MSL Level 1 rating ensures compatibility with lead-free reflow processes used in automotive manufacturing.
What does the "HE3" suffix indicate in SMBG100HE3/52?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this grade from commercial "E3" variants (e.g., SMBG100A-E3/52), which lack automotive qualification and use Class 1A whisker testing. The HE3 version is intended for mission-critical automotive and industrial deployments.
How does SMBG100HE3/52 differ from SMBJ100A in practical design?
SMBG100HE3/52 uses the DO-215AA (SMBG) package with gull-wing leads and is AEC-Q101 qualified, whereas SMBJ100A uses DO-214AA (SMB) with J-bend leads and lacks automotive qualification. The SMBG variant offers lower profile height and tighter thermal resistance control (RθJA = 100 °C/W), while SMBJ provides higher power density (RθJA = 85 °C/W) but less stringent reliability validation.
What is the maximum operating temperature for SMBG100HE3/52?
The SMBG100HE3/52 has a maximum junction temperature (TJ) of +150 °C and an operating junction/storage temperature range of -55 °C to +150 °C. At elevated ambient temperatures, derating applies: per Figure 2 in the datasheet, pulse power must be reduced linearly above TA = 25 °C, reaching ~50 % of rated PPPM at TA ≈ 75 °C with standard pad layout.
