Product details
Overview
SMBJ100AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 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 - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom infrastructure.
For engineers reviewing the SMBJ100AHE3_B/H datasheet, SMBJ100AHE3_B/H pinout, SMBJ100AHE3_B/H application, or SMBJ100AHE3_B/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 to +150 °C), and RoHS-compliant packaging details for rapid ESD/surge protection design-in.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, optimized for fast response (<1 ns) to voltage spikes induced by inductive switching or lightning surges. Its glass-passivated junction ensures stable leakage performance (ID ≤ 1.0 µA at VWM) and low incremental surge resistance under repetitive 0.01% duty cycle conditions.
The SMBJ100AHE3_B/H is rated for 5.0 W steady-state power dissipation at TA = 50 °C and supports 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine). Thermal design requires attention to pad layout: derating applies above 25 °C ambient per Fig. 2, and RθJL = 20 °C/W enables effective lead-to-board heat transfer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 12 V–48 V DC bus protection. |
| VBR (min/max) | 111 V / 123 V at IT = 1 mA - guaranteed breakdown threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 162 V at 3.7 A - clamping voltage limits downstream component stress during 600 W transient energy absorption. |
| PPPM | 600 W with 10/1000 µs waveform - specifies single-pulse surge handling capability compliant with IEC 61000-4-5 Level 4. |
| TJ max. | +150 °C - enables operation in high-temperature environments such as automotive engine control units or industrial motor drives. |
| RθJA | 100 °C/W - thermal resistance value used to calculate junction temperature rise above ambient for PCB layout validation. |
| AEC-Q101 | Qualified - confirms reliability for automotive electronics applications including body control modules and infotainment power rails. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Polarity marked by cathode band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during forward surge (e.g., reverse-bias fault). |
| Cathode | Clamping terminal | Connected to higher-potential side (e.g., VCC rail); initiates avalanche breakdown when reverse voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables robust protection against IEC 61000-4-5 combined wave surges up to 4 kV without degradation. |
| Glass passivated junction | Ensures long-term stability of leakage current and breakdown voltage across temperature and humidity cycles. |
| MSL Level 1 (260 °C) | Supports standard SMT reflow profiles without moisture-related popcorning or delamination risk. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, and UHAST testing per AEC specification. |
| Low profile SMB package | Reduces board space vs. SMA/SMB alternatives while maintaining thermal performance via copper pad layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100AHM3_B/H | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification. | No functional difference; selected where halogen-free material compliance is mandated (e.g., EU automotive Tier 1 programs). | Choose SMBJ100AHM3_B/H when halogen-free bill-of-materials is required; otherwise SMBJ100AHE3_B/H suffices. |
| SMCJ100AHE3_A/H | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package with higher RθJA (60 °C/W) and 1500 W PPPM rating. | Used where higher surge energy handling (>600 W) or improved thermal margin is needed, e.g., outdoor telecom cabinets. | Select SMCJ100AHE3_A/H only if system-level surge testing exceeds 600 W or board layout allows larger footprint. |
Compared with SMBJ100AHE3_B/H, the HM3 variant offers identical protection performance with halogen-free construction, while the SMCJ100AHE3_A/H provides higher surge capacity in a physically larger package - neither is pin-compatible, requiring PCB redesign for substitution.

FAQ
What is the maximum clamping voltage of SMBJ100AHE3_B/H under specified test conditions?
The SMBJ100AHE3_B/H has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak pulse current (IPPM) of 3.7 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components experience no more than 162 V during standardized surge events - critical for safeguarding 100 V-rated capacitors and logic-level interfaces in SMBJ100AHE3_B/H-based designs.
Is SMBJ100AHE3_B/H qualified for automotive applications?
Yes, SMBJ100AHE3_B/H is AEC-Q101 qualified, confirming its suitability for automotive electronics including body control modules, lighting drivers, and infotainment power rails. The qualification covers stress tests such as high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress testing (UHAST), all performed per the AEC-Q101 standard - making SMBJ100AHE3_B/H appropriate for under-hood and cabin applications where reliability is mandatory.
What does the "HE3" suffix indicate in SMBJ100AHE3_B/H?
The "HE3" suffix in SMBJ100AHE3_B/H denotes a RoHS-compliant, commercial-grade version that is also AEC-Q101 qualified. The "H" indicates the packaging configuration (7″ tape and reel, 750 units), while "E3" specifies the environmental compliance level - distinct from "HM3" (halogen-free + RoHS + AEC-Q101) or "E3/52" (same compliance, different reel size). This coding ensures traceability and correct material declaration for SMBJ100AHE3_B/H in regulated supply chains.
How does SMBJ100AHE3_B/H compare to bidirectional TVS diodes like SMBJ100CA?
SMBJ100AHE3_B/H is unidirectional and intended for DC line protection where polarity is fixed, offering lower leakage (≤1.0 µA at 100 V) and tighter VBR tolerance than bidirectional variants. In contrast, SMBJ100CA provides symmetrical clamping for AC or floating signal lines but exhibits higher ID (≤2.0 µA) and reduced precision in breakdown symmetry. Use SMBJ100AHE3_B/H for VCC/GND rail protection and SMBJ100CA only when bidirectional surge immunity is explicitly required - they are not interchangeable without circuit review.
What PCB layout considerations apply to SMBJ100AHE3_B/H for optimal thermal performance?
For optimal thermal performance, SMBJ100AHE3_B/H must be mounted on minimum recommended copper pads: 0.2″ × 0.2″ (5.0 mm × 5.0 mm) per terminal, per Vishay's datasheet Fig. 2 derating curve. Smaller pads increase RθJA beyond the rated 100 °C/W, risking junction overheating during repeated surges. Additionally, avoid thermal relief on pads and ensure solid copper connections to internal ground/power planes - these practices maintain SMBJ100AHE3_B/H's ability to dissipate 5.0 W continuously at TA = 50 °C.
