Product details
Overview
SMB10J13AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range (VBR), and 1000 W peak pulse power (10/1000 µs). It delivers 46.5 A peak pulse current (IPPM) and clamps transients to ≤21.5 V, making it suitable for automotive power line and sensor interface protection.
For engineers reviewing the SMB10J13AHE3/5B datasheet, SMB10J13AHE3/5B pinout, SMB10J13AHE3/5B application, or SMB10J13AHE3/5B equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity, 1000 W surge rating, low clamping ratio (VC/VBR ≈ 1.45), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuitry, activating when reverse voltage exceeds its breakdown threshold (VBR = 14.4–15.9 V at IT = 1.0 mA). Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM = 13 V) and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion during 10/1000 µs transients.
Thermally, it features RθJA = 72 °C/W and RθJL = 20 °C/W, supporting operation from –55 °C to +150 °C junction temperature. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification-critical for automotive ECUs, body control modules, and ADAS sensor interfaces requiring long-term reliability under load dump and ISO 7637-2 pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR min/max | 14.4 V / 15.9 V - Breakdown occurs within this range at 1.0 mA test current; ensures consistent turn-on across production lots. |
| VC @ IPPM | ≤21.5 V - Clamped voltage during 46.5 A 10/1000 µs surge; limits stress on downstream ICs like microcontrollers or CAN transceivers. |
| PPPM | 1000 W - Peak pulse power handling per 10/1000 µs waveform; supports robust protection against ISO 16750-2 load dump events. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at 13 V; negligible power loss and no signal integrity impact in high-impedance sensor lines. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments without derating. |
| 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. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Same VWM (13 V), VBR (14.4–15.9 V), and PPPM (1000 W), but commercial-grade (non-AEC-Q101) and E3 suffix only. | Lacks automotive qualification; suitable for industrial or consumer designs where AEC-Q101 is not mandated. | Select SMBJ13A-E3/52 for cost-sensitive non-automotive applications with identical electrical performance. |
| 1.5SMC13AHE3/A | Higher package thermal resistance (RθJA = 11°C/W vs. 72°C/W), same VWM/VBR, but SMC (DO-214AB) package with larger footprint (7.11 mm × 6.22 mm). | Lower power density; requires more PCB area and may need layout revision due to different pad dimensions. | Choose 1.5SMC13AHE3/A only if higher single-pulse energy handling is needed and board space permits larger SMC package. |
Compared with SMBJ13A-E3/52 and 1.5SMC13AHE3/A, SMB10J13AHE3/5B uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and full 1000 W capability-making it the optimal choice for space-constrained automotive electronics requiring certified reliability.

FAQ
What is the clamping voltage of SMB10J13AHE3/5B under maximum surge conditions?
The SMB10J13AHE3/5B clamps to a maximum of 21.5 V when subjected to its rated 46.5 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This clamping voltage is measured at the device terminals under defined test conditions and ensures protected circuits remain below critical overvoltage thresholds. The SMB10J13AHE3/5B maintains this performance across its full operating temperature range.
Is SMB10J13AHE3/5B suitable for automotive applications?
Yes, SMB10J13AHE3/5B is AEC-Q101 qualified and explicitly intended for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its construction-including glass-passivated junction, matte tin-plated leads, and MSL Level 1 rating-meets stringent automotive reliability requirements. The HE3 suffix confirms both RoHS compliance and AEC-Q101 qualification for the SMB10J13AHE3/5B.
What is the standoff voltage (VWM) and why does it matter for SMB10J13AHE3/5B?
The standoff voltage (VWM) of SMB10J13AHE3/5B is 13 V, representing the maximum continuous reverse voltage the device can block without significant conduction. This value establishes the design margin between normal operating voltage and breakdown onset, ensuring reliable operation during nominal 12 V automotive system conditions while allowing headroom for ripple and transients. Exceeding VWM risks premature conduction and power loss in the SMB10J13AHE3/5B.
How does the SMB10J13AHE3/5B package compare to DO-214AB (SMC)?
The SMB10J13AHE3/5B uses the smaller SMB (DO-214AA) package-5.59 mm × 4.06 mm-versus the larger SMC (DO-214AB) at 7.11 mm × 6.22 mm. While both handle 1000 W, the SMB offers higher power density and fits tighter layouts. Thermal resistance differs significantly: SMB10J13AHE3/5B has RθJA = 72 °C/W, whereas SMC variants typically achieve ~11 °C/W due to greater copper exposure-so layout and heatsinking must be optimized per package for the SMB10J13AHE3/5B.
What is the peak pulse current rating for SMB10J13AHE3/5B and how is it tested?
The SMB10J13AHE3/5B is rated for 46.5 A peak pulse current (IPPM) using the standardized 10/1000 µs double-exponential waveform per ANSI/IEEE C62.35. This test applies a single surge pulse with 10 µs rise time and 1000 µs decay to 50% of peak, mounted on 5.0 mm × 5.0 mm copper pads per terminal. The SMB10J13AHE3/5B sustains this current without parametric shift or failure, validating its robustness against real-world transients like ISO 7637-2 pulses.
